It looks like it's not working in newer version of Mockito. Mockito forbids mocking types which have complex contracts or easy to construct by other means. It throws the exception `'context' is mocking 'class android.content.Context'. Don't mock android components, as they have lots of state and complex behavior - use the real thing. A Context can be obtained from ApplicationProvider.getApplicationContext() in Robolectric tests, or from InstrumentationRegistry in emulator tests..` – Farruh Habibullaev Jul 02 '21 at 04:36

If you want to get the context with Kotlin and Mockito, you can do it in the following way:

mock(Context::class.java)

Don't mock types you don't own. But why? let's say you are mocking a third-party library, if the maintainers of that library made changes, then your tests will be executed because it is a mock and you think everything is okay, but it is not because there are changes that you are not aware of, and things can go badly.
