test 0.12.8

A library for writing dart unit tests.

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.

##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.
