Convenient extensions to the scala-test library.

common-scala-test

Contains code for testing your Scala code, building on ScalaTest and Mockito.

Using Mockito Syrup

The AnswerSugar trait makes it easier to work with Mockito Answers in Scala. Instead of creating an Answer[T] object and overriding answer(), you can pass in a closure to the method. In other words, instead of writing:

when(myMock.method()).thenAnswer(new Answer[ReturnType] {
  override def answer(invocation: InvocationOnMock): ReturnType = "My result"
}

you can write:

when(myMock.method()).thenAnswer(() => { "My result" })

The MatcherSugar trait allows you to write Matchers as anonymous functions in Scala. Instead of creating a Matcher[T] object and overriding matches/describeTo, you can pass in a closure to the method. In other words, instead of writing:

verify(myMock).method(argThat(new Matcher[String] {
  override def matches(item: Any): Boolean = item == "test string"
  override def describeTo(description: Description): Unit = description.appendText("test string")
}))

you can write:

verify(myMock).method(argThat{ arg: String => arg == "test string" })
