A library for writing dart unit tests.

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 Futures and Streams 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.

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

• 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 package to use ASCII glyphs when the test runner is running on Windows.

• 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 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.

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.

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.

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.

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

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.

• Skipped groups now properly print skip messages.

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.

• Improve the display of syntax errors in VM tests.

• Work around a Firefox bug. Computed styles now work in tests on Firefox.

• 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.

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.
