ScalaTest + MockitoThe ScalaTest + Mockito integration library makes it fun and easy to use Mockito with ScalaTest. To use ScalaTest + Mockito, please add the following to your SBT project dependency: libraryDependencies += "org.scalatestplus" %% "mockito-5-12" % "3.2.19.0" % "test" For maven you can use: <dependency> <groupId>org.scalatestplus</groupId> <artifactId>mockito-5-12_3</artifactId> <version>3.2.19.0</version> <scope>test</scope> </dependency> Mockito 5 requires JDK 11, if you are on JDK 8, you'll need to use mockito-4-11 instead.
Using the Mockito API directly, you create a mock with: val mockCollaborator = mock(classOf[Collaborator]) Using this trait, you can shorten that to: val mockCollaborator = mock[Collaborator]
Here is how the example used in the previous EasyMock and JMock sections would look with Mockito and // First, create the mock object val mockCollaborator = mock[Collaborator] // Create the class under test and pass the mock to it classUnderTest = new ClassUnderTest classUnderTest.addListener(mockCollaborator) // Use the class under test classUnderTest.addDocument("Document", new Array[Byte](0)) classUnderTest.addDocument("Document", new Array[Byte](0)) classUnderTest.addDocument("Document", new Array[Byte](0)) classUnderTest.addDocument("Document", new Array[Byte](0)) // Then verify the class under test used the mock object as expected verify(mockCollaborator).documentAdded("Document") verify(mockCollaborator, times(3)).documentChanged("Document") |
