I'm trying to mock a simple interface in my Kotlin project, but receiving the following error:

Mockito cannot mock this class: interface MyInterface.

Mockito can only mock non-private & non-final classes.

I'm using org.mockito.kotlin:mockito-kotlin:2.2.10 and my interface is indeed in the same package as the test. I have also tried inline mockmaker

@CluEleSsUK Could you post the test also?

Sorry, I ended up switching things to mockK, so no longer have the test - it was fairly mickey mouse though!
Something to the effect of:

val mock = mock(MyInterface::class)
val objectUnderTest = Thing(mock)
given(mock.someFn(any()).thenReturn("1234")
val result = objectUnderTest.start()
assertTrue(result)

Some things I tried:

  • inline mock-maker
  • all-open plugin
  • spring-all-open
  • using a slightly older version of mockito and mockito-kotlin
  • trying different java versions (8 and 14)

Sorry I can't provide you any more info!
