The below code reproduces it:
object CompilerSpec extends BaseSpec {
val tests = Tests {
'default - {
null
}
}
}
I didn't intend to return null in a test. But my last statement in the test was Mockito's verify, which seemed to returns null; and that caused the exception.
I was using the version 0.6.3.
I wonder how we can fix it. Thank you.
