mockito 3.0.0

A mock framework inspired by Mockito.

3.0.0

• Deprecate the typed API; instead of wrapping other Mockito API calls, like any, argThat, captureAny, and captureArgThat, with a call to typed, the regular API calls are to be used by themselves. Passing any and captureAny as named arguments must be replaced with anyNamed() and captureAnyNamed, respectively. Passing argThat and captureThat as named arguments must include the named parameter.

• Introduce a backward-and-forward compatible API to help users migrate to Mockito 3. See more details in the upgrading-to-mockito-3 doc.

• thenReturn now throws an ArgumentError if either a Future or Stream is provided. thenReturn calls with futures and streams should be changed to thenAnswer. See the README for more information.

• Support stubbing of void methods in Dart 2.

• thenReturn and thenAnswer now support generics and infer the correct types from the when call.

• Completely remove the mirrors implementation of Mockito (mirrors.dart).

• Fix compatibility with new noSuchMethod Forwarding feature of Dart 2. This is thankfully a mostly backwards-compatible change. This means that this version of Mockito should continue to work:

  • with Dart >=2.0.0-dev.16.0,
  • with Dart 2 runtime semantics (i.e. with dart --preview-dart-2, or with Flutter Beta 3), and
  • with the new noSuchMethod Forwarding feature, when it lands in CFE, and when it lands in DDC.

  This change, when combined with noSuchMethod Forwarding, will break a few code paths which do not seem to be frequently used. Two examples:

  class A {
    int fn(int a, [int b]) => 7;
  }
  class MockA extends Mock implements A {}
  
  var a = new MockA();
  when(a.fn(typed(any), typed(any))).thenReturn(0);
  print(a.fn(1));
  

  This used to print null, because only one argument was passed, which did not match the two-argument stub. Now it will print 0, as the real call contains a value for both the required argument, and the optional argument.

  a.fn(1);
  a.fn(2, 3);
  print(verify(a.fn(typed(captureAny), typed(captureAny))).captured);
  

  This used to print [2, 3], because only the second call matched the verify call. Now, it will print [1, null, 2, 3], as both real calls contain a value for both the required argument, and the optional argument.

• Upgrade package dependencies.

• Throw an exception when attempting to stub a method on a Mock object that already exists.

2.2.0

• Add new feature to wait for an interaction: untilCalled. See the README for documentation.
• capture* calls outside of a verify* call no longer capture arguments.
• Some collections require stricter argument matching. For example, a stub like: mock.methodWithListArgs([1,2,3].map((e) => e*2)) (note the Iterable argument) will no longer match the following stub: when(mock.methodWithListArgs([42])).thenReturn(7);.

2.1.0

• Add documentation for when, verify, verifyNever, resetMockitoState.
• Expose throwOnMissingStub, resetMockitoState.
• Improve failure message for verify.
• SDK version ceiling bumped to <2.0.0-dev.infinity to support Dart 2.0 development testing.
• Add a Mockito + test package example at test/example/iss.

2.0.2

• Start using the new InvocationMatcher instead of the old matcher.
• Change throwOnMissingStub back to invoking Object.noSuchMethod:
  • It was never documented what the thrown type should be expected as.
  • You can now just rely on throwsNoSuchMethodError if you want to catch it.

2.0.1

• Add a new throwOnMissingStub method to the API.

2.0.0

• Removed mockito_no_mirrors.dart

2.0.0-dev

• Remove export of spy and any dart:mirrors based API from mockito.dart. Users may import as package:mockito/mirrors.dart going forward.
• Deprecated mockito_no_mirrors.dart; replace with mockito.dart.
• Require Dart SDK >=1.21.0 <2.0.0 to use generic methods.

1.0.1

• Add a new thenThrow method to the API.
• Document thenAnswer in the README.
• Add more dartdoc.

1.0.0

• Add a new typed API that is compatible with Dart Dev Compiler; documented in README.md.

0.11.1

• Move the reflection-based spy code into a private source file. Now package:mockito/mockito.dart includes this reflection-based API, and a new package:mockito/mockito_no_mirrors.dart doesn't require mirrors.

0.11.0

• Equality matcher used by default to simplify matching collections as arguments. Should be non-breaking change in most cases, otherwise consider using argThat(identical(arg)).

0.10.0

• Added support for spy.

0.9.0

• Migrate from the unittest package to use the new test package.
• Format code using dartformat
