## 1.29.0

* Add `--coverage-package` flag, which filters the coverage report to specific
  packages using RegExps.
* Require a function definition named `main` directly in a test suite and
  provide a more direct error message than a failing compiler output.
* Suppress skip reason messages in the compact and failures-only reporters.
* Allow `analyzer` major version 10.

## 1.28.0

* Add `isSorted` and related matchers for iterables.
* Consider `NaN` to be equal to itself in `equals`.
* Bump `test_core` to 0.6.14
* Removed unused `js` dependency

## 1.26.1

* Set a debug name for test isolates.
* Fix an assertion failure when using `setUpAll` or `tearDownAll` and running
  with asserts enabled.

## 1.26.0

* `test()` and `group()` functions now take an optional `TestLocation` that will
  be used as the location of the test in JSON reporters instead of being parsed
  from the call stack.

## 1.25.15

* Allow the latest version of `package:shelf_web_socket`.

## 1.25.14

* Use secure random for url secrets.

## 1.25.13

## 1.25.12

* Fix hang when running multiple precompiled browser tests.

## 1.25.11

* Update to be forward compatible with `package:shelf_web_socket` version `3.x`.

## 1.25.10

* Update the `package:vm_service` constraint to allow version `15.x`.

## 1.25.9

* Allow `analyzer: '>=6.0.0 <8.0.0'`
* Fix dart2wasm tests on windows.

* Added [`@doNotSubmit`](https://pub.dev/documentation/meta/latest/meta/doNotSubmit-constant.html) to `test(solo: ...)` and `group(solo: ...)`. In
  practice, this means that code that was relying on ignoring deprecation
  warnings and using `solo` or `group` with a `skip` parameter will now fail if
  `dart analyze --fatal-infos` (or similar) is enabled.

## 1.25.2

* Fix a bug running browser tests with paths containing windows directory
  separator follow by a character which is an invalid Dart string escape
  sequence.

## 1.25.1

* Fix a bug where in precompiled mode, html files for tests were no longer
  created.
* Support the latest version of `package:js`.
* Document the silent reporter in CLI help output.

## 1.25.0

* Handle paths with leading `/` when spawning test isolates.
* Add support for the `dart2wasm` compiler in chrome and firefox.
* **BREAKING**: Remove the `experimental-chrome-wasm` platform, you can now use
  `-p chrome -c dart2wasm` instead.
  * Note that this has always been advertised as a change that would happen in a
    future non-breaking release.
* **BREAKING**:Dropped support for `--pub-serve` which has long not been tested
  or supported.
  * We do not anticipate much if any actual breakage or existing usage of this
    feature, which is why we are making this change in a non-breaking release.
  * If you do require this feature, file an issue and we can look at adding it
    back.
* **BREAKING**: Fully remove support for Internet Explorer.
* Fix running of tests defined under `lib/` with relative imports to other
  libraries in the package.

## 1.24.9

* Update the vm_service constraint to allow version `13.x`.

## 1.24.8

* Remove spurious deprecation during autocomplete for `setUp` and `tearDown`.

  tests. See https://github.com/dart-lang/test/issues/2065
* Add a timeout to browser test suite loads.
* Fix running of browser tests that use deferred loaded libraries.

## 1.24.6

* Fix communication failures between minified test apps and the non-minified
  host app.
* Add support for discontinuing after the first failing test with `--fail-fast`.

## 1.24.5

* Change `compiling <path>` to `loading <path>` message in all cases. Surface
  the "loading" messages in the situations where previously only the
  "compiling" message would be used.
* Support browser tests where the frame creates the message channel.

## 1.24.4

* Drop support for null unsafe Dart, bump SDK constraint to `3.0.0`.
* Make some annotation classes `final`: `OnPlatform`, `Retry`, `Skip`, `Tags`,
  `TestOn`, `Timeout`.
* Fix the `root_` fields in the JSON reporter when running a test on Windows
  with an absolute path.
* Add support for `SAFARI_EXECUTABLE`, `FIREFOX_EXECUTABLE` and
  `MS_EDGE_EXECUTABLE` for custom browser installations.
* Allow the latest analyzer (6.x.x).
* Add `MOZ_AUTOMATION=1` environmental variable to Firefox runner, to make
  launcher process on Windows wait for browser exit.

## 1.24.3

* Fix compatibility with wasm number semantics.

## 1.24.2

* Copy an existing nonce from a script on the test HTML page to the script
  created by the test runner host javascript. This only impacts environments
  testing with custom HTML that includes a nonce.
* Support the Microsoft Edge browser (use the `edge` platform in your test
  configuration file or `-p edge` on the command line).

## 1.24.1

* Handle a missing `'compiler'` value when running a test compiled against a
  newer `test_api` than the runner back end is using. The expectation was that
  the json protocol is only used across packages compatible with the same major
  version of the `test_api` package, but `flutter test` does not check the
  version of packages in the pub solve for user test code.

## 1.24.0

* Support the `--compiler` flag, which can be used to configure which compiler
  to use.
  * To specify a compiler by platform, the argument supports platform selectors
    through this syntax `[<platform>:]<compiler>`. For example the command line
    argument `--compiler vm:source` would run all vm tests from source instead
    of compiling to kernel first.
  * If no given compiler is compatible for a platform, it will use its default
    compiler instead.
* Add support for running tests as native executables (vm platform only).
  * You can run tests this way with `--compiler exe`.
* Support compiler identifiers in platform selectors.
* List the supported compilers for each platform in the usage text.
* Update all reporters to print the compiler along with the platform name
  when configured to print the platform. Extend the logic for printing platofrm
  information to do so if any compilers are explicitly configured.
* Deprecate `--use-data-isolate-strategy`. It is now an alias for `-c vm:source`
  which is roughly equivalent. If this is breaking for you please file an issue.

## 1.23.1

* Fix running paths by absolute path (with drive letter) on windows.

## 1.23.0

* Avoid empty expandable groups for tests without extra output in Github
  reporter.
* Add support for CHROME_EXECUTABLE environment variable. This overrides any
  config file settings.
* Support running tests by absolute file uri.

## 1.22.2

* Don't run `tearDown` until the test body and outstanding work is complete,
  even if the test has already failed.
* Change URL secrets for browser tests to always be alphanumeric characters.

## 1.22.1

* Add documentation for the `--ignore-timeouts` argument.
* Merge command lines args repeating the same test path to run the suite one
  time with all the test cases across the different arguments.
* Fix VM tests which run after some test has changed the working directory.
  There are still issues with browser tests after changing directory.
* Deprecate `throwsNullThrownError`, use `throwsA(isA<TypeError>())` instead. The
  implementation has been changed to ease migrations.
* Deprecate `throwsCyclicInitializationError` and replace the implementation
  with `Throws(TypeMatcher<Error>())`. The specific exception no longer exists
  and there is no guarantee about what type of error will be thrown.

## 1.22.0

* Fix an issue with the github reporter where tests that fail asynchronously
  after they've completed would show up as succeeded tests.
* Add the `experimental-chrome-wasm` platform. This is very unstable and will
  eventually be deleted, to be replaced by a `--compiler` flag. See
  https://github.com/dart-lang/test/issues/1776 for more information on future
  plans.

## 1.21.7

  reporters, use gray instead of black.
* Print a command to re-run the failed test after each failure in the compact
  reporter.
* Fix the package config path used when running pre-compiled vm tests.

## 1.21.3

* Support the latest `package:test_api` and `package:test_core`.

## 1.21.2

* Add `Target` to restrict `TestOn` annotation to library level.
* Update the github reporter to output the platform in the test names when
  multiple platforms are used.
* Fix `spawnHybridUri` support for `package:` uris.

## 1.21.1

* Fix a bug loading JS sources with non-utf8 content while parsing coverage
  information from chrome.

## 1.21.0

* Allow analyzer version `4.x`.
* Add a `github` reporter option for use with GitHub Actions.

  GitHub Actions.

## 1.20.2

* Allow loading tests under a path with the directory named `packages`.
* Add retry for launching browsers. Reduce timeout back to 30 seconds.

## 1.20.1

* Allow the latest `vm_service` package.

## 1.20.0

* Update `analyzer` constraint to `>=2.0.0 <4.0.0`.
* Add an `--ignore-timeouts` command line flag, which disables all timeouts
  for all tests. This can be useful when debugging, so tests don't time out
  during debug sessions.
* Create a trusted types policy when available for assigning the script URL for
  web tests.

## 1.19.5

* Try to get more logging from `chrome` on windows to diagnose intermittent
  failures.

## 1.19.4

* Wait for paused VM platform isolates before shutdown.
* `TestFailure` implements `Exception` for compatibility with
  `only_throw_exceptions`.

## 1.19.3

* Remove duplicate logging of suggestion to enable the `chain-stack-traces`
  flag, a single log will now appear at the end.

## 1.19.2

* Republish with missing JS file for browser tests.

## 1.19.1

* Fix parsing of file paths into a URI on windows.

## 1.19.0

* Support query parameters `name`, `full-name`, `line`, and `col` on test paths,
  which will apply the filters to only those test suites.
  * All specified filters must match for a test to run.
  * Global filters (ie: `--name`) are also still respected and must match.
  * The `line` and `col` will match if any frame from the test trace matches
    (the test trace is the current stack trace where `test` is invoked).
* Give a better exception when using `markTestSkipped` outside of a test.

## 1.18.2

* Publish with the `host.dart.js` file.

## 1.18.1

* Add defaulting for older test backends that don't pass a configuration for
  the `allow_duplicate_test_names` parameter to the remote listener.

* Re-use the cached dill file from previous runs on subsequent runs.

## 1.17.11

* Use the latest `package:matcher`.
  * Change many argument types from `dynamic` to `Object?`.
  * Fix `stringContainsInOrder` to account for repetitions and empty strings.
    * **Note**: This may break some existing tests, as the behavior does change.

## 1.17.10

* Report incomplete tests as errors in the JSON reporter when the run is
  canceled early.
* Update `analyzer` constraint to `>=1.0.0 <3.0.0`.

## 1.17.9

  tag to ignore the `--test-randomize-ordering-seed` argument.

## 1.17.8

* Update json reporter docs with updated nullability annotations and
  descriptions.

* Fix an issue where you couldn't have tests compiled in both sound and
  unsound null safety modes.

## 1.17.0

* Change the default way VM tests are launched and ran to greatly speed up
  loading performance.
  * You can force the old strategy with `--use-data-isolate-strategy` flag if
    you run into issues, but please also file a bug.
* Disable stack trace chaining by default. It can be re-enabled by explicitly
  passing the `--chain-stack-traces` flag.

## 1.16.0-nullsafety.12

* Fix `spawnHybridUri` on windows.
* Fix failures running tests on the `node` platform.
* Allow `package:yaml` version `3.x.x`.

## 1.16.0-nullsafety.11

* Set up a stack trace mapper in precompiled mode if source maps exist. If
  the stack traces are already mapped then this has no effect, otherwise it
  will try to map any JS lines it sees.

## 1.16.0-nullsafety.10

* Allow injecting a test channel for browser tests.
* Allow `package:analyzer` version `0.41.x`.

## 1.16.0-nullsafety.9

## 1.16.0-nullsafety

* Support running tests with null safety.
  * Note that the test runner itself is not fully migrated yet.
* Add the `Fake` class, available through `package:test_api/fake.dart`.  This
  was previously part of the Mockito package, but with null safety it is useful
  enough that we decided to make it available through `package:test`.  In a
  future release it will be made available directly through
  `package:test_api/test_api.dart` (and hence through
  `package:test_core/test_core.dart` and `package:test/test.dart`).

  the same language version as the test.
* The Node platform will now communicate over only IPv6 if it is available.

## 1.14.7

* Support the latest `package:coverage`.


## 1.14.6

  no tests defined.
* Fix the stack trace labels in SDK code for `dart2js` compiled tests.

  is done matching.
  * This fixes a bug where using a matcher on a custom stream controller and
    then awaiting the `close()` method on that controller would hang.
* Avoid causing the test runner to hang if there is a timeout during a
  `tearDown` callback following a failing test case.

## 1.12.0

* Bump minimum SDK to `2.4.0` for safer usage of for-loop elements.
* Deprecate `PhantomJS` and provide warning when used. Support for `PhantomJS`
  will be removed in version `2.0.0`.
* Support coverage collection for the Chrome platform. See `README.md` for usage
  details.

## 1.11.1

* Allow `test_api` `0.2.13` to work around a bug in the SDK version `2.3.0`.

## 1.11.0

* Add `file_reporters` configuration option and `--file-reporter` CLI option to
  allow specifying a separate reporter that writes to a file instead of stdout.

## 1.10.0

* Add `customHtmlTemplateFile` configuration option to allow sharing an
  html template between tests

## 1.8.0

* Expose the previously hidden sharding arguments
  * `--total-shards` specifies how many shards the suite should
    be split into
  * `--shard-index` specifies which shard should be run

## 1.7.0

## 1.6.11

* Depend on the latest `test_core` and `test_api`.

## 1.6.10

* Internal cleanup - fix lints.

## 1.6.3

* Depend on latest `package:test_core`.
  * This fixes an issue where non-completed tests were considered passing.

## 1.6.2

* Avoid `dart:isolate` imports on code loaded in tests.

## 1.6.1

* Allow `stream_channel` version `2.0.0`.

## 1.6.0

* Allow `analyzer` version `0.36.x`.
* Matcher changes:
  * Add `isA()` to create `TypeMatcher` instances in a more fluent way.
  * Add `isCastError`.
  * **Potentially breaking bug fix**. Ordering matchers no longer treat objects
    with a partial ordering (such as NaN for double values) as if they had a
    complete ordering. For instance `greaterThan` now compares with the `>`
    operator rather not `<` and not `=`. This could cause tests which relied on
    this bug to start failing.

## 1.5.3

* Allow `analyzer` version `0.35.x`.

## 1.5.2

* Require Dart SDK `>=2.1.0`.
* Depend on latest `test_core` and `test_api`.

## 1.5.1

* Depend on latest `test_core` and `test_api`.

## 1.5.0

* Depend on `package:test_core` for core functionality.

## 1.4.0

* Depend on `package:test_api` for core functionality.

## 1.3.4

* Allow remote_listener to be closed and sent an event on close.

## 1.3.3

* Add conditional imports so that `dart:io` is not imported from the main
  `test.dart` entrypoint unless it is available.
* Fix an issue with dartdevc in precompiled mode and the json reporter.
* Fix an issue parsing test metadata annotations without explicit `const`.

## 1.3.2

* Widen the constraints on the analyzer package.

## 1.3.1

* Handle parsing annotations which omit `const` on collection literals.
* Fix an issue where `root_line`, `root_column`, and `root_url` in the
  JSON reported may not be populated correctly on Windows.
* Removed requirement for the test/pub_serve transformer in --pub-serve mode.

## 1.3.0

* When using `--precompiled`, the test runner now allows symlinks to reach
  outside the precompiled directory. This allows more efficient creation of
  precompiled directories (using symlinks instead of copies).
* Updated max sdk range to `<3.0.0`.

## 1.2.0

* Added support for using precompiled kernel files when running vm tests.
  * When using the `--precompiled` flag we will now first check for a
    `<original-test-path>.vm_test.vm.app.dill` file, and if present load that
    directly in the isolate. Otherwise the `<original-test-path>.vm_test.dart`
    file will be used.

## 1.1.0

* Added a new `pid` field to the StartEvent in the json runner containing the
  pid of the VM process running the tests.

## 1.0.0

* No change from `0.12.42`. We are simply signalling to users that this is a
  well supported package and is the preferred way to write Dart tests.

## 0.12.42

* Add support for `solo` test and group. When the argument is `true` only tests
  and groups marked as solo will be run. It is still recommended that users
  instead filter their tests by using the runner argument `-n`.

* Updated exported `package:matcher` to `0.12.3` which includes these updates:

  - Many improvements to `TypeMatcher`
    - Can now be used directly as `const TypeMatcher<MyType>()`.
    - Added a type parameter to specify the target `Type`.
      - Made the `name` constructor parameter optional and marked it deprecated.
        It's redundant to the type parameter.
    - Migrated all `isType` matchers to `TypeMatcher`.
    - Added a `having` function that allows chained validations of specific
      features of the target type.

      ```dart
      /// Validates that the object is a [RangeError] with a message containing
      /// the string 'details' and `start` and `end` properties that are `null`.
      final _rangeMatcher = isRangeError
         .having((e) => e.message, 'message', contains('details'))
         .having((e) => e.start, 'start', isNull)
         .having((e) => e.end, 'end', isNull);
      ```

  - Deprecated the `isInstanceOf` class. Use `TypeMatcher` instead.

  - Improved the output of `Matcher` instances that fail due to type errors.

## 0.12.41

* Add support for debugging VM tests.
* Tweak default reporter and color logic again so that they are always enabled
  on all non-windows platforms.

## 0.12.40

* Added some new optional fields to the json reporter, `root_line`,
  `root_column`, and `root_url`. These will be present if `url` is not the same
  as the suite url, and will represent the location in the original test suite
  from which the call to `test` originated.

## 0.12.39

* Change the default reporter and color defaults to be based on
  `stdout.supportsAnsiEscapes` instead of based on platform (previously both
  were disabled on windows).

## 0.12.38+3

* Fix Dart 2 runtime errors around communicating with browsers.


## 0.12.38+2

* Fix more Dart 2 runtime type errors.

## 0.12.38+1

* Fix several Dart 2 runtime type errors.

## 0.12.38

* Give `neverCalled` a type that works in Dart 2 semantics.
* Support `package:analyzer` `0.32.0`.

## 0.12.37

* Removed the transformer, and the `pub_serve.dart` entrypoint. This is not
  being treated as a breaking change because the minimum sdk constraint now
  points to an sdk which does not support pub serve or barback any more anyways.
* Drop the dependency on `barback`.

## 0.12.36

* Expose the test bootstrapping methods, so that build systems can precompile
  tests without relying on internal apis.

## 0.12.35

* Dropped support for Dart 1. Going forward only Dart 2 will be supported.
  * If you experience blocking issues and are still on the Dart 1 sdk, we will
    consider bug fixes on a per-case basis based on severity and impact.
  * Drop support for `dartium` and `content-shell` platforms since those are
    removed from the Dart 2 SDK.
* Fixed an issue `--precompiled` node tests in subdirectories.
* Fixed some dart2 issues with node test bootstrapping code so that dartdevc
  tests can run.
* Fixed default custom html handler so it correctly includes the
  packages/test/dart.js file. This allows you to get proper errors instead of
  timeouts if there are load exceptions in the browser.
* Upgrade to package:matcher 0.12.2

## 0.12.34

* Requires at least Dart 1.24.0.
* The `--precompiled` flag is now supported for the vm platform and the node
  platform.
* On browser platforms the `--precompiled` flag now serves all sources directly
  from the precompiled directory, and will never attempt to do its own
  compilation.

## 0.12.33

* Pass `--categories=Server` to `dart2js` when compiling tests for Node.js. This
  tells it that `dart:html` is unavailable.

* Don't crash when attempting to format stack traces when running via
  `dart path/to/test.dart`.

## 0.12.32+2

* Work around an SDK bug that caused timeouts in asynchronous code.

## 0.12.32+1

* Fix a bug that broke content shell on Dart 1.24.

## 0.12.32

* Add an `include` configuration field which specifies the path to another
  configuration file whose configuration should be used.

* Add a `google` platform selector variable that's only true on Google's
  internal infrastructure.

## 0.12.31

* Add a `headless` configuration option for Chrome.

* Re-enable headless mode for Chrome by default.

* Don't hang when a Node.js test fails to compile.

## 0.12.30+4

* Stop running Chrome in headless mode temporarily to work around a browser bug.

## 0.12.30+3

* Fix a memory leak when loading browser tests.

## 0.12.30+2

* Avoid loading test suites whose tags are excluded by `--excluded-tags`.

## 0.12.30+1

* Internal changes.

## 0.12.30

* Platform selectors for operating systems now work for Node.js tests
  ([#742][]).

* `fail()` is now typed to return `Null`, so it can be used in the same places
  as a raw `throw`.

* Run Chrome in headless mode unless debugging is enabled.

[#742]: https://github.com/dart-lang/test/issues/742

## 0.12.29+1

* Fix strong mode runtime cast failures.

## 0.12.29

* Node.js tests can now import modules from a top-level `node_modules`
  directory, if one exists.

* Raw `console.log()` calls no longer crash Node.js tests.

* When a browser crashes, include its standard output in the error message.

## 0.12.28+1

* Add a `pumpEventQueue()` function to make it easy to wait until all
  asynchronous tasks are complete.

* Add a `neverCalled` getter that returns a function that causes the test to
  fail if it's ever called.

## 0.12.27+1

* Increase the timeout for loading tests to 12 minutes.

## 0.12.27

* When `addTearDown()` is called within a call to `setUpAll()`, it runs its
  callback after *all* tests instead of running it after the `setUpAll()`
  callback.

* When running in an interactive terminal, the test runner now prints status
  lines as wide as the terminal and no wider.

## 0.12.26+1

* Fix lower bound on package `stack_trace`. Now 1.6.0.
* Manually close browser process streams to prevent test hangs.

## 0.12.26

* The `spawnHybridUri()` function now allows root-relative URLs, which are
  interpreted as relative to the root of the package.

## 0.12.25

* Add a `override_platforms` configuration field which allows test platforms'
  settings (such as browsers' executables) to be overridden by the user.

* Add a `define_platforms` configuration field which makes it possible to define
  new platforms that use the same logic as existing ones but have different
  settings.

## 0.12.24+8

* `spawnHybridUri()` now interprets relative URIs correctly in browser tests.

## 0.12.24+7

* Declare support for `async` 2.0.0.

## 0.12.24+6

* Small refactoring to make the package compatible with strong-mode compliant Zone API.
  No user-visible change.

## 0.12.24+5

* Expose a way for tests to forward a `loadException` to the server.

## 0.12.24+4

* Drain browser process `stdout` and `stdin`. This resolves test flakiness, especially in Travis
  with the `Precise` image.

## 0.12.24+3

* Extend `deserializeTimeout`.

## 0.12.24+2

* Only force exit if `FORCE_TEST_EXIT` is set in the environment.

## 0.12.24+1

* Widen version constraint on `analyzer`.

## 0.12.24

* Add a `node` platform for compiling tests to JavaScript and running them on
  Node.js.

## 0.12.23+1

* Remove unused imports.

## 0.12.23

* Add a `fold_stack_frames` field for `dart_test.yaml`. This will
  allow users to customize which packages' frames are folded.

## 0.12.22+2

* Properly allocate ports when debugging Chrome and Dartium in an IPv6-only
  environment.

## 0.12.22+1

* Support `args` 1.0.0.

* Run tear-down callbacks in the same error zone as the test function. This
  makes it possible to safely share `Future`s and `Stream`s between tests and
  their tear-downs.

## 0.12.22

* Add a `retry` option to `test()` and `group()` functions, as well
  as `@Retry()`  annotation for test files and a `retry`
  configuration field for `dart_test.yaml`.  A test with reties
  enabled will be re-run if it fails for a reason other than a
  `TestFailure`.

* Add a `--no-retry` runner flag that disables retries of failing tests.

* Fix a "concurrent modification during iteration" error when calling
  `addTearDown()` from within a tear down.

## 0.12.21

* Add a `doesNotComplete` matcher that asserts that a Future never completes.

* `throwsA()` and all related matchers will now match functions that return
  `Future`s that emit exceptions.

* Respect `onPlatform` for groups.

* Only print browser load errors once per browser.

* Gracefully time out when attempting to deserialize a test suite.

## 0.12.20+13

* Upgrade to package:matcher 0.12.1

## 0.12.20+12

* Now support `v0.30.0` of `pkg/analyzer`

* The test executable now does a "hard exit" when complete to ensure lingering
  isolates or async code don't block completion. This may affect users trying
  to use the Dart service protocol or observatory.

## 0.12.20+11

* Refactor bootstrapping to simplify the test/pub_serve transformer.

## 0.12.20+10

* Refactor for internal tools.

## 0.12.20+9

* Introduce new flag `--chain-stack-traces` to conditionally chain stack traces.

## 0.12.20+8

* Fixed more blockers for compiling with `dev_compiler`.
* Dartfmt the entire repo.

* **Note:** 0.12.20+5-0.12.20+7 were tagged but not officially published.

## 0.12.20+4

* Fixed strong-mode errors and other blockers for compiling with `dev_compiler`.

## 0.12.20+3

* `--pause-after-load` no longer deadlocks with recent versions of Chrome.

* Fix Dartified stack traces for JS-compiled tests run through `pub serve`.

## 0.12.20+2

* Print "[E]" after test failures to make them easier to identify visually and
  via automated search.

## 0.12.20+1

* Tighten the dependency on `stream_channel` to reflect the APIs being used.

* Use a 1024 x 768 iframe for browser tests.

## 0.12.20

* **Breaking change:** The `expect()` method no longer returns a `Future`, since
  this broke backwards-compatibility in cases where a void function was
  returning an `expect()` (such as `void foo() => expect(...)`). Instead, a new
  `expectLater()` function has been added that return a `Future` that completes
  when the matcher has finished running.

* The `verbose` parameter to `expect()` and the `formatFailure()` function are
  deprecated.

## 0.12.19+1

* Make sure asynchronous matchers that can fail synchronously, such as
  `throws*()` and `prints()`, can be used with synchronous matcher operators
  like `isNot()`.

## 0.12.19

* Added the `StreamMatcher` class, as well as several built-in stream matchers:
  `emits()`, `emitsError()`, `emitsDone, mayEmit()`, `mayEmitMultiple()`,
  `emitsAnyOf()`, `emitsInOrder()`, `emitsInAnyOrder()`, and `neverEmits()`.

* `expect()` now returns a Future for the asynchronous matchers `completes`,
  `completion()`, `throws*()`, and `prints()`.

* Add a `printOnFailure()` method for providing debugging information that's
  only printed when a test fails.

* Automatically configure the [`term_glyph`][term_glyph] package to use ASCII
  glyphs when the test runner is running on Windows.

[term_glyph]: https://pub.dev/packages/term_glyph

* Deprecate the `throws` matcher in favor of `throwsA()`.

* Deprecate the `Throws` class. These matchers should only be constructed via
  `throwsA()`.

## 0.12.18+1

* Fix the deprecated `expectAsync()` function. The deprecation caused it to
  fail to support functions that take arguments.

## 0.12.18

* Add an `addTearDown()` function, which allows tests to register additional
  tear-down callbacks as they're running.

* Add the `spawnHybridUri()` and `spawnHybridCode()` functions, which allow
  browser tests to run code on the VM.

* Fix the new `expectAsync` functions so that they don't produce analysis errors
  when passed callbacks with optional arguments.

## 0.12.17+3

* Internal changes only.

## 0.12.17+2

* Fix Dartium debugging on Windows.

## 0.12.17+1

* Fix a bug where tags couldn't be marked as skipped.

## 0.12.17

* Deprecate `expectAsync` and `expectAsyncUntil`, since they currently can't be
  made to work cleanly in strong mode. They are replaced with separate methods
  for each number of callback arguments:
  * `expectAsync0`, `expectAsync1`, ... `expectAsync6`, and
  * `expectAsyncUntil0`, `expectAsyncUntil1`, ... `expectAsyncUntil6`.

## 0.12.16

* Allow tools to interact with browser debuggers using the JSON reporter.

## 0.12.15+12

* Fix a race condition that could cause the runner to stall for up to three
  seconds after completing.

## 0.12.15+11

* Make test iframes visible when debugging.

## 0.12.15+10

* Throw a better error if a group body is asynchronous.

## 0.12.15+9

* Widen version constraint on `analyzer`.

## 0.12.15+8

* Make test suites with thousands of tests load much faster on the VM (and
  possibly other platforms).

## 0.12.15+7

* Fix a bug where tags would be dropped when `on_platform` was defined in a
  config file.

## 0.12.15+6

* Fix a broken link in the `--help` documentation.

## 0.12.15+5

* Internal-only change.

## 0.12.15+4

* Widen version constraint on `analyzer`.

## 0.12.15+3

* Move `nestingMiddleware` to `lib/src/util/path_handler.dart` to enable a
  cleaner separation between test-runner files and test writing files.

## 0.12.15+2

* Support running without a `packages/` directory.

## 0.12.15+1

* Declare support for version 1.19 of the Dart SDK.

## 0.12.15

* Add a `skip` parameter to `expect()`. Marking a single expect as skipped will
  cause the test itself to be marked as skipped.

* Add a `--run-skipped` parameter and `run_skipped` configuration field that
  cause tests to be run even if they're marked as skipped.

## 0.12.14+1

* Narrow the constraint on `yaml`.

## 0.12.14

* Add test and group location information to the JSON reporter.

## 0.12.13+5

* Declare support for version 1.18 of the Dart SDK.

* Use the latest `collection` package.

## 0.12.13+4

* Compatibility with an upcoming release of the `collection` package.

## 0.12.13+3

* Internal changes only.

## 0.12.13+2

* Fix all strong-mode errors and warnings.

## 0.12.13+1

* Declare support for version 1.17 of the Dart SDK.

## 0.12.13

* Add support for a global configuration file. On Windows, this file defaults to
  `%LOCALAPPDATA%\DartTest.yaml`. On Unix, it defaults to `~/.dart_test.yaml`.
  It can also be explicitly set using the `DART_TEST_CONFIG` environment
  variable. See [the configuration documentation][global config] for details.

* The `--name` and `--plain-name` arguments may be passed more than once, and
  may be passed together. A test must match all name constraints in order to be
  run.

* Add `names` and `plain_names` fields to the package configuration file. These
  allow presets to control which tests are run based on their names.

* Add `include_tags` and `exclude_tags` fields to the package configuration
  file. These allow presets to control which tests are run based on their tags.

* Add a `pause_after_load` field to the package configuration file. This allows
  presets to enable debugging mode.

[global config]: https://github.com/dart-lang/test/blob/master/pkgs/test/doc/configuration.md#global-configuration

## 0.12.12

* Add support for [test presets][]. These are defined using the `presets` field
  in the package configuration file. They can be selected by passing `--preset`
  or `-P`, or by using the `add_presets` field in the package configuration
  file.

* Add an `on_os` field to the package configuration file that allows users to
  select different configuration for different operating systems.

* Add an `on_platform` field to the package configuration file that allows users
  to configure all tests differently depending on which platform they run on.

* Add an `ios` platform selector variable. This variable will only be true when
  the `test` executable itself is running on iOS, not when it's running browser
  tests on an iOS browser.

[test presets]: https://github.com/dart-lang/test/blob/master/pkgs/test/doc/package_config.md#configuration-presets

## 0.12.11+2

* Update to `shelf_web_socket` 0.2.0.

## 0.12.11+1

* Purely internal change.

## 0.12.11

* Add a `tags` field to the package configuration file that allows users to
  provide configuration for specific tags.

* The `--tags` and `--exclude-tags` command-line flags now allow
  [boolean selector syntax][]. For example, you can now pass `--tags "(chrome ||
  firefox) && !slow"` to select quick Chrome or Firefox tests.

[boolean selector syntax]: https://github.com/dart-lang/boolean_selector/blob/master/README.md

## 0.12.10+2

* Re-add help output separators.

* Tighten the constraint on `args`.

## 0.12.10+1

* Temporarily remove separators from the help output. Version 0.12.8 was
  erroneously released without an appropriate `args` constraint for the features
  it used; this version will help ensure that users who can't use `args` 0.13.1
  will get a working version of `test`.

## 0.12.10

* Add support for a package-level configuration file called `dart_test.yaml`.

## 0.12.9

* Add `SuiteEvent` to the JSON reporter, which reports data about the suites in
  which tests are run.

* Add `AllSuitesEvent` to the JSON reporter, which reports the total number of
  suites that will be run.

* Add `Group.testCount` to the JSON reporter, which reports the total number of
  tests in each group.

## 0.12.8

* Organize the `--help` output into sections.

* Add a `--timeout` flag.

## 0.12.7

* Add the ability to re-run tests while debugging. When the browser is paused at
  a breakpoint, the test runner will open an interactive console on the command
  line that can be used to restart the test.

* Add support for passing any object as a description to `test()` and `group()`.
  These objects will be converted to strings.

* Add the ability to tag tests. Tests with specific tags may be run by passing
  the `--tags` command-line argument, or excluded by passing the
  `--exclude-tags` parameter.

  This feature is not yet complete. For now, tags are only intended to be added
  temporarily to enable use-cases like [focusing][] on a specific test or group.
  Further development can be followed on [the issue tracker][issue 16].

* Wait for a test's tear-down logic to run, even if it times out.

[focusing]: https://jasmine.github.io/2.1/focused_specs.html
[issue 16]: https://github.com/dart-lang/test/issues/16

## 0.12.6+2

* Declare compatibility with `http_parser` 2.0.0.

## 0.12.6+1

* Declare compatibility with `http_multi_server` 2.0.0.

## 0.12.6

* Add a machine-readable JSON reporter. For details, see
  [the protocol documentation][json-protocol].

* Skipped groups now properly print skip messages.

[json-protocol]: https://github.com/dart-lang/test/blob/master/pkgs/test/json_reporter.md

## 0.12.5+2

* Declare compatibility with Dart 1.14 and 1.15.

## 0.12.5+1

* Fixed a deadlock bug when using `setUpAll()` and `tearDownAll()`.

## 0.12.5

* Add `setUpAll()` and `tearDownAll()` methods that run callbacks before and
  after all tests in a group or suite. **Note that these methods are for special
  cases and should be avoided**—they make it very easy to accidentally introduce
  dependencies between tests. Use `setUp()` and `tearDown()` instead if
  possible.

* Allow `setUp()` and `tearDown()` to be called multiple times within the same
  group.

* When a `tearDown()` callback runs after a signal has been caught, it can now
  schedule out-of-band asynchronous callbacks normally rather than having them
  throw exceptions.

* Don't show package warnings when compiling tests with dart2js. This was
  accidentally enabled in 0.12.2, but was never intended.

## 0.12.4+9

* If a `tearDown()` callback throws an error, outer `tearDown()` callbacks are
  still executed.

## 0.12.4+8

* Don't compile tests to JavaScript when running via `pub serve` on Dartium or
  content shell.

## 0.12.4+7

* Support `http_parser` 1.0.0.

## 0.12.4+6

* Fix a broken link in the README.

## 0.12.4+5

* Internal changes only.

## 0.12.4+4

* Widen the Dart SDK constraint to include `1.13.0`.

## 0.12.4+3

* Make source maps work properly in the browser when not using `--pub-serve`.

## 0.12.4+2

* Fix a memory leak when running many browser tests where old test suites failed
  to be unloaded when they were supposed to.

## 0.12.4+1

* Require Dart SDK >= `1.11.0` and `shelf` >= `0.6.0`, allowing `test` to remove
  various hacks and workarounds.

## 0.12.4

* Add a `--pause-after-load` flag that pauses the test runner after each suite
  is loaded so that breakpoints and other debugging annotations can be added.
  Currently this is only supported on browsers.

* Add a `Timeout.none` value indicating that a test should never time out.

* The `dart-vm` platform selector variable is now `true` for Dartium and content
  shell.

* The compact reporter no longer prints status lines that only update the clock
  if they would get in the way of messages or errors from a test.

* The expanded reporter no longer double-prints the descriptions of skipped
  tests.

## 0.12.3+9

* Widen the constraint on `analyzer` to include `0.26.0`.

## 0.12.3+8

* Fix an uncaught error that could crop up when killing the test runner process
  at the wrong time.

## 0.12.3+7

* Add a missing dependency on the `collection` package.

## 0.12.3+6

**This version was unpublished due to [issue 287][].**

* Properly report load errors caused by failing to start browsers.

* Substantially increase browser timeouts. These timeouts are the cause of a lot
  of flakiness, and now that they don't block test running there's less harm in
  making them longer.

## 0.12.3+5

**This version was unpublished due to [issue 287][].**

* Fix a crash when skipping tests because their platforms don't match.

## 0.12.3+4

**This version was unpublished due to [issue 287][].**

* The compact reporter will update the timer every second, rather than only
  updating it occasionally.

* The compact reporter will now print the full, untruncated test name before any
  errors or prints emitted by a test.

* The expanded reporter will now *always* print the full, untruncated test name.

## 0.12.3+3

**This version was unpublished due to [issue 287][].**

* Limit the number of test suites loaded at once. This helps ensure that the
  test runner won't run out of memory when running many test suites that each
  load a large amount of code.

## 0.12.3+2

**This version was unpublished due to [issue 287][].**

[issue 287]: https://github.com/dart-lang/test/issues/287

* Improve the display of syntax errors in VM tests.

* Work around a [Firefox bug][]. Computed styles now work in tests on Firefox.

[Firefox bug]: https://bugzilla.mozilla.org/show_bug.cgi?id=548397

* Fix a bug where VM tests would be loaded from the wrong URLs on Windows (or in
  special circumstances on other operating systems).

## 0.12.3+1

* Fix a bug that caused the test runner to crash on Windows because symlink
  resolution failed.

## 0.12.3

* If a future matched against the `completes` or `completion()` matcher throws
  an error, that error is printed directly rather than being wrapped in a
  string. This allows such errors to be captured using the Zone API and improves
  formatting.

* Improve support for Polymer tests. This fixes a flaky time-out error and adds
  support for Dartifying JavaScript stack traces when running Polymer tests via
  `pub serve`.

* In order to be more extensible, all exception handling within tests now uses
  the Zone API.

* Add a heartbeat to reset a test's timeout whenever the test interacts with the
  test infrastructure.

* `expect()`, `expectAsync()`, and `expectAsyncUntil()` throw more useful errors
  if called outside a test body.

## 0.12.2

* Convert JavaScript stack traces into Dart stack traces using source maps. This
  can be disabled with the new `--js-trace` flag.

* Improve the browser test suite timeout logic to avoid timeouts when running
  many browser suites at once.

## 0.12.1

* Add a `--verbose-trace` flag to include core library frames in stack traces.

## 0.12.0

### Test Runner

`0.12.0` adds support for a test runner, which can be run via
`pub run test:test` (or `pub run test` in Dart 1.10). By default it runs all
files recursively in the `test/` directory that end in `_test.dart` and aren't
in a `packages/` directory.

The test runner supports running tests on the Dart VM and many different
browsers. Test files can use the `@TestOn` annotation to declare which platforms
they support. For more information on this and many more new features, see [the
README](README).

[README]: https://github.com/dart-lang/test/blob/master/README.md

### Removed and Changed APIs

As part of moving to a runner-based model, most test configuration is moving out
of the test file and into the runner. As such, many ancillary APIs have been
removed. These APIs include `skip_` and `solo_` functions, `Configuration` and
all its subclasses, `TestCase`, `TestFunction`, `testConfiguration`,
`formatStacks`, `filterStacks`, `groupSep`, `logMessage`, `testCases`,
`BREATH_INTERVAL`, `currentTestCase`, `PASS`, `FAIL`, `ERROR`, `filterTests`,
`runTests`, `ensureInitialized`, `setSoloTest`, `enableTest`, `disableTest`, and
`withTestEnvironment`.

`FailureHandler`, `DefaultFailureHandler`, `configureExpectFailureHandler`, and
`getOrCreateExpectFailureHandler` which used to be exported from the `matcher`
package have also been removed. They existed to enable integration between
`test` and `matcher` that has been streamlined.

A number of APIs from `matcher` have been into `test`, including: `completes`,
`completion`, `ErrorFormatter`, `expect`,`fail`, `prints`, `TestFailure`,
`Throws`, and all of the `throws` methods. Some of these have changed slightly:

* `expect` no longer has a named `failureHandler` argument.

* `expect` added an optional `formatter` argument.

* `completion` argument `id` renamed to `description`.

## 0.11.6+4

* Fix some strong mode warnings we missed in the `vm_config.dart` and

## 0.10.1

* **DEPRECATED**
  * `matcher.dart` and `mirror_matchers.dart` are now in the `matcher`
    package.
  * `mock.dart` is now in the `mock` package.
* `equals` now allows a nested matcher as an expected list element or map value
  when doing deep matching.
* `expectAsync` and `expectAsyncUntil` now support up to 6 positional arguments
  and correctly handle functions with optional positional arguments with default
  values.

## 0.10.0

* Each test is run in a separate `Zone`. This ensures that any exceptions that
  occur is async operations are reported back to the source test case.
* **DEPRECATED** `guardAsync`, `protectAsync0`, `protectAsync1`,
  and `protectAsync2`
  * Running each test in a `Zone` addresses the need for these methods.
* **NEW!** `expectAsync` replaces the now deprecated `expectAsync0`,
  `expectAsync1` and `expectAsync2`
* **NEW!** `expectAsyncUntil` replaces the now deprecated `expectAsyncUntil0`,
  `expectAsyncUntil1` and `expectAsyncUntil2`
* `TestCase`:
  * Removed properties: `setUp`, `tearDown`, `testFunction`
  * `enabled` is now get-only
  * Removed methods: `pass`, `fail`, `error`
* `interactive_html_config.dart` has been removed.
* `runTests`, `tearDown`, `setUp`, `test`, `group`, `solo_test`, and
  `solo_group` now throw a `StateError` if called while tests are running.
* `rerunTests` has been removed.
