* Fix dart2wasm tests on windows.
* Increase SDK constraint to ^3.5.0.
* Allow passing additional arguments to `dart compile wasm`.

## 0.6.5

* Increase SDK constraint to ^3.4.0.
* Ensure we don't create files ending in a `.`, this breaks windows.

## 0.6.4

* Enable asserts for `dart2wasm` tests.

## 0.6.3

* Update min SDK constraint to 3.2.0.
* Fix testing with `dart2wasm` - use `dart compile wasm` instead of depending on
  SDK internals

## 0.6.2

* Add `@doNotSubmit` to more declarations of the `solo` parameter.

## 0.6.1

* Handle missing package configs.
* Document the silent reporter in CLI help output.
* Support enabling experiments with the dart2wasm compiler.

## 0.6.0

* Handle paths with leading `/` when spawning test isolates.
* Added `dart2wasm` as a supported compiler for the `chrome` runtime.
* **BREAKING**: Removed the `experimentalChromeWasm` runtime.
* **BREAKING**: Removed `Runtime.isJS` and `Runtime.isWasm`, as this is now
  based on the compiler and not the runtime.
* **BREAKING**: Removed `Configuration.pubServeUrl` and support for it.
* Fix running of tests defined under `lib/` with relative imports to other
  libraries in the package.
* Update the `package:frontend_server_client` constraint to allow version
  `4.0.0`.
* Update the `package:vm_service` constraint to allow version `14.x`.

## 0.5.9

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

## 0.5.8

* Move scaffolding definitions to a non-deprecated library.
* Allow omitting the `Compiler` argument to `currentPlatform`.

## 0.5.7

* Pass --disable-program-split to dart2js to fix tests which use deferred
  loading.
* Add a 'silent' reporter option. Keep it hidden in the CLI args help since it
  is not useful in the general case, but can be useful for tests of the test
  runner.
* Update to `package:vm_service` `12.0.0`

## 0.5.6

* Add support for discontinuing after the first failing test with `--fail-fast`.

## 0.5.5

* Change "compiling <path>" to "loading <path>" message in all cases. Surface
  the "loading" messages in the situations where previously only "compiling"
  message would be used.

## 0.5.4

* Drop support for null unsafe Dart, bump SDK constraint to `3.0.0`.
* Add `final` modifier on some implementation classes: `Configuration`,
  `CustomRuntime`,`RuntimeSettings`, `SuiteConfiguration`.
* Fix the `root_` fields in the JSON reporter when running a test on Windows
  with an absolute path.
* Allow the latest analyzer (6.x.x).

## 0.5.3

* Fix compatibility with wasm number semantics.

## 0.5.2

* Use the version `0.5.2` of `packge:test_api`.

## 0.5.1

* Start adding experimental support for native_assets.yaml, when
  `--enable-experiment=native_assets` is passed.

## 0.5.0

* 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 `-c exe` (the native executable compiler) to the vm platform.
* Add `Compiler` class, exposed through `backend.dart`.
* 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.
* **BREAKING** Add required `defaultCompiler` and `supportedCompilers` fields
  to `Runtime`.
* **BREAKING** Add required `compiler` field to `SuitePlatform`.
* **BREAKING** Add required `compilerSelections` argument to some
  `Configuration` and `SuiteConfiguration` constructors.
* **BREAKING** Custom platform plugins need to respect the compiler option
  given through the `SuitePlatform` argument to `PlatformPlugin.load`. This is
  not statically breaking but it will be confusing for users if it isn't
  supported.
* **BREAKING** Remove `useDataIsolateStrategy` field from `Configuration`.
* **BREAKING** Stop exporting APIs from `package:matcher/expect.dart`.

## 0.4.24

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

## 0.4.23

* Don't run `tearDown` until the test body and outstanding work is complete,
  even if the test has already failed.
* Update `vm_service` constraint to `>=6.0.0 <11.0.0`.

## 0.4.21

* Move `includeTags` and `excludeTags` from `SuiteConfiguration` to
  `Configuration`.

  time with all the test cases across the different arguments.

  reporter.
* Fix the package config path used when running pre-compiled vm tests.

## 0.4.15

  multiple platforms are used.

  for all tests.

  configures VM platform tests to pause for debugging after tests are run,
  before the test isolates are killed.

## 0.4.9

* Wait for paused VM platform isolates before shutdown.

## 0.4.8

* Add logging about enabling stack trace chaining to the compact and expanded
  reporters (moved from the invoker). This will now only be logged once after
  all tests have ran.

## 0.4.7

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

## 0.4.6

* 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).
* Support the latest `test_api`.

## 0.4.5

* Use newer analyzer APIs.

## 0.4.4

* Support the latest `test_api`.

## 0.4.3

## 0.4.1

* Use the latest `package:matcher`.

  constructors are now required. Some specialized constructors have been added
  for the common cases where a subset are intended to be provided.

* Report incomplete tests as errors in the JSON reporter when the run is
  canceled early.
* Don't log the --test-randomization-ordering-seed if using the json reporter.
* Add a new exit code, 79, which is used when no tests were ran.
  * Previously you would have gotten either exit code 1 or 65 (65 if you had
    provided a test name regex).
* When no tests were ran but tags were provided, list the tag configuration.
* Update `analyzer` constraint to `>=1.0.0 <3.0.0`.

## 0.3.29

* Fix a bug where a tag level configuration would cause test suites with that
  tag to ignore the `--test-randomize-ordering-seed` argument.

## 0.3.28

* Add `time` field to the json reporters `allSuites` event type so that all
  event types can be unified.

## 0.3.27

* Restore the `Configuration.loadFromString` constructor.

## 0.3.26

* Give a better error when `printOnFailure` is called from outside a test
  zone.

  unsound null safety modes.

## 0.3.20

* Change the default way VM tests are launched and ran to greatly speed up
  loading performance.

* Improve the error message for `hybridMain` functions with an incompatible
  StreamChannel parameter type.
* Change the `message` argument to `PlatformPlugin.load` to `Map<String,
  Object?>`. In an upcoming release this will be required as the type for this
  argument when passed through to `deserializeSuite`.

  * The loading and running of a test are now done with the same resource, and
    the concurrency setting uniformly affects each. With `-j1` only a single
    test will ever be loaded at a time.
  * Previously the loading pool was 2x larger than the actual concurrency

  and depend on them from `test_api`.

## 0.1.0
