unittest

• 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.

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.
• 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

##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.
