PowerMockito: got InvalidUseOfMatchersException when use matchers mocking static method

Question

When I\'m testing this static method

public class SomeClass {
    public static long someMethod(Map map, String string, Long l, Log log) {
        ...
    }
         


        

Answer 1

Better late than never, the line below:

Mockito.when(SomeClass.someMethod(anyMap(), anyString(), anyLong(),
    isA(Log.class))).thenReturn(1L);

should be:

PowerMockito.when(SomeClass.someMethod(anyMap(), anyString(), anyLong(),
    isA(Log.class))).thenReturn(1L);

So, instead of invoking Mockito.when, one should invoke PowerMockito.when
