How to return Array of Objects using Powermock and mockito

Question

I have a method which return array of object.

public IConfigurationElement[] getConfigurationElementsFor(String extensionPointId);

I am not sure how can I mock this call using mockito and powermock.

I have tried

mockConfigurationElements = (IConfigurationElement[]) Mockito.anyListOf( IConfigurationElement.class ).toArray();

but this is ending in ClassCastException.

Answer 1

Mocking (stubbing) calls with Mockito is done in a following way (for example):

Mockito.when(mockObject.getConfigurationElementsFor(Mockito.anyString()).thenReturn(new IConfigurationElement[]{})

or

Mockito.doReturn(new IConfigurationElement[]{}).when(mockObject).getConfigurationElementsFor(Mockito.anyString());

Mockito.anyListOf() is a use of a matcher. Matchers are passed instead of real arguments when stubbing meaning that the behavior is to be applied if the method is called with arguments satisfying those matchers.
