## 0.12.3

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

## 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).

### 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`.

##0.11.5+1

* Internal code cleanups and documentation improvements.

##0.11.5

* Bumped the version constraint for `matcher`.

##0.11.4

* Bump the version constraint for `matcher`.

##0.11.3

* Narrow the constraint on matcher to ensure that new features are reflected in
  unittest's version.

##0.11.2

* Prints a warning instead of throwing an error when setting the test
  configuration after it has already been set. The first configuration is always
  used.

##0.11.1+1

* Fix bug in withTestEnvironment where test cases were not reinitialized if
  called multiple times.

##0.11.1

* Add `reason` named argument to `expectAsync` and `expectAsyncUntil`, which has
  the same definition as `expect`'s `reason` argument.
* Added support for private test environments.

##0.11.0+6

* Refactored package tests.

##0.11.0+5

* Release test functions after each test is run.

##0.11.0+4

* Fix for [20153](https://code.google.com/p/dart/issues/detail?id=20153)

##0.11.0+3

* Updated maximum `matcher` version.

##0.11.0+2

*  Removed unused files from tests and standardized remaining test file names.

##0.11.0+1

* Widen the version constraint for `stack_trace`.

##0.11.0

* Deprecated methods have been removed:
    * `expectAsync0`, `expectAsync1`, and `expectAsync2` - use `expectAsync`
      instead
    * `expectAsyncUntil0`, `expectAsyncUntil1`, and `expectAsyncUntil2` - use
      `expectAsyncUntil` instead
    * `guardAsync` - no longer needed
    * `protectAsync0`, `protectAsync1`, and `protectAsync2` - no longer needed
* `matcher.dart` and `mirror_matchers.dart` have been removed. They are now in
  the `matcher` package.
* `mock.dart` has been removed. It is now in the `mock` package.

##0.10.1+2

* Fixed deprecation message for `mock`.

##0.10.1+1

* Fixed CHANGELOG
* Moved to triple-slash for all doc comments.

##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.
