matcher 0.12.1+1

Support for specifying test expectations, such as for unit tests.

The matcher library provides a third-generation assertion mechanism, drawing inspiration from Hamcrest.

For more information, see Unit Testing with Dart.

0.12.1+1

  • Produce a better error message when a CustomMatcher's feature throws.

0.12.1

  • Add containsAllInOrder matcher for Iterables

0.12.0+2

  • Fix all strong-mode warnings.

0.12.0+1

  • Fix test files to use test instead of unittest pkg.

0.12.0

  • Moved a number of members to the unittest package.

    • TestFailure, ErrorFormatter, expect, fail, and 'wrapAsync'.
    • completes, completion, throws, and throwsA Matchers.
    • The Throws class.
    • All of the throws...Error Matchers.
  • Removed FailureHandler, DefaultFailureHandler, configureExpectFailureHandler, and getOrCreateExpectFailureHandler. Now that expect is in the unittest package, these are no longer needed.

  • Removed the name parameter for isInstanceOf. This was previously deprecated, and is no longer necessary since all language implementations now support converting the type parameter to a string directly.

0.11.4+6

  • Fix a bug introduced in 0.11.4+5 in which operator matchers broke when taking lists of matchers.

0.11.4+5

  • Fix all strong-mode warnings.

0.11.4+4

  • Deprecate the name parameter to isInstanceOf. All language implementations now support converting the type parameter to a string directly.

0.11.4+3

  • Fix the examples for equalsIgnoringWhitespace.

0.11.4+2

  • Improve the formatting of strings that contain unprintable ASCII characters.

0.11.4+1

  • Correctly match and print Strings containing characters that must be represented as escape sequences.

0.11.4

  • Remove the type checks in the isEmpty and isNotEmpty matchers and simply access the isEmpty respectively isNotEmpty fields. This allows them to work with custom collections. See Issue 21792 and Issue 21562

0.11.3+1

  • Fix the prints matcher test on dart2js.

0.11.3

  • Add a prints matcher that matches output a callback emits via print.

0.11.2

  • Add an isNotEmpty matcher.

0.11.1+1

  • Refactored libraries and tests.

  • Fixed spelling mistake.

0.11.1

  • Added isNaN and isNotNaN matchers.

0.11.0

  • Removed deprecated matchers.

0.10.1+1

  • Get the tests passing when run on dart2js in minified mode.

0.10.1

  • Compare sets order-independently when using equals().

0.10.0+3

  • Removed @deprecated annotation on matchers due to Issue 19173

0.10.0+2

  • Added types to a number of constants.

0.10.0+1

  • Matchers related to bad language use have been removed. These represent code structure that should rarely or never be validated in tests.

    • isAbstractClassInstantiationError
    • throwsAbstractClassInstantiationError
    • isFallThroughError
    • throwsFallThroughError
  • Added types to a number of method arguments.

  • The structure of the library and test code has been updated.

1. Depend on it

Add this to your package's pubspec.yaml file:

dependencies:
  matcher: "^0.12.1+1"

2. Install it

You can install packages from the command line:

$ pub get

Alternatively, your editor might support 'pub get'. Check the docs for your editor to learn more.

3. Import it

Now in your Dart code, you can use:

import 'package:matcher/matcher.dart';
