How Can I Mock Final Classes and Methods with Mockito?

Mocking Private or Final Methods/Classes with Mockito

When working with testing, mocking final classes or methods is a common challenge. Mockito, a popular mocking framework, traditionally faced limitations in this aspect. However, with the release of Mockito v2, this obstacle has been overcome.

To mock a final class with Mockito v2, follow these steps:

  1. Include Mockito v2 in Gradle:

    testImplementation 'org.mockito:mockito-inline:2.13.0'
  2. Mock the Class Directly:

    // Given
    FinalClass finalClass = mock(FinalClass.class);

    Note that you do not need to declare the @Mock annotation, as in older Mockito versions.
