If defaultAnswer is set to throw exception, then equals does not cause exception to be thrown

[aSemy]

I wanted to make a mock that would never be called. I set defaultAnswer to throw an exception for everything. This works for most methods, but not for equals()

Maybe this is an underlying Mockito or Kotlin issue?

In this example, it is mockedUUID.timestamp() that throws an exception (which is good), but mockedUUID.equals("false") does not (which is unexpected).

  @Test
  fun testDefaultAnswer() {
    val mockedUUID : UUID = mock(
        defaultAnswer = ThrowsException(IllegalStateException("default answer"))
    )

    assertFalse(mockedUUID.equals("false"))
    mockedUUID.timestamp()
  }

java.lang.IllegalStateException: default answer

@aSemy This might be intended behavior. This issue should probably be reported to the main Mockito project, as the implementation is delegated to Mockito.

Mostly likely - thanks for taking a look.

I've moved on to a different bit of work so I'll close this issue.
