Mocking an object in Scala using PowerMock
I'm trying to unit test one of my methods. Inside this method it has a line:
val dynamicFrame = DynamicFrame(dataFrame, glueContext)
The issue is that DynamicFrame is an object:
object DynamicFrame
... methods()
and I'm trying to use PowerMock to mock the call to DynamicFrame(dataFrame, glueContext). I know that PowerMock can mock classes, but how can I mock an object? I've seen similar questions here and here but it doesn't seem straightforward.
In my test code I've tried
PowerMockito.whenNew(classOf[DynamicFrame])
.withAnyArguments().thenReturn(mockDynamicFrame)
but I get a NullPointerException on the line where DynamicFrame is created. My guess is that it's because I used syntax for mocking classes but DynamicFrame is an object.
Does PowerMock (from Mockito) support this functionality out of the gate? If not how would I go about making my test succeed?
