I'm having a strange behaviour while stubbing method that takes case classes as parameters.
I'm still trying to understand why, but in one case I'm getting a
You cannot use argument matchers outside of verification or stubbing.
Examples of correct usage of argument matchers:
when(mock.get(anyInt())).thenReturn(null);
doThrow(new RuntimeException()).when(mock).someVoidMethod(anyObject());
verify(mock).someMethod(contains("foo"))
When stubbing like this
simpleTrait.anotherMethod(any[Param]) returns "Mock String"
and I have to change it like this
simpleTrait.anotherMethod(Param(anyInt)) returns "Mock String"
Where
case class Param(val: Int)
and
trait SimpleTrait {
def anotherMethod(someParam: Param): String
}
Both the behaviour seems equivalent, though.
Any Ideas?
