Duplicate class definition when try to use KotlinTestRunner #14

Closed stepango closed 8 years ago

stepango commented 8 years ago

This error appears even if I adding open modifier to class full stacktrace:

Mockito cannot mock this class: class com.ninetyseconds.auckland.navigation.AppNavigationActions

Mockito can only mock visible & non-final classes.
If you're not sure why you're getting this error, please report to the mailing list.

I see bytebuddy in the stacktrace. what version of mocktito are you using?

We've seen a similar issue with early beta of mockito2

I tried with 1.10.19 and 2.0.106-beta

stepango commented 8 years ago

Issue related to 2.0.52-beta, caused by kotlin-mockito dependency
