Powermockito doNothing for method with arguments

Question

I\'ve developed an application in Java and I\'m trying to create unit tests using Powermockito (I should add that I\'m new to unit testing).

I have a class called Re

You can find a fully functional example below. Since you didn't post the complete example, I can only assume that you did not annotate the test class with @RunWith or @PrepareForTest because the rest seems fine.

@RunWith(PowerMockRunner.class)
@PrepareForTest({Resource.class})
public class MockingTest{

    @Test
    public void shouldMockVoidStaticMethod() throws Exception {
        PowerMockito.spy(Resource.class);
        PowerMockito.doNothing().when(Resource.class, "readResources", Mockito.any(String.class));

        //no exception heeeeere!
        Resource.readResources("whatever");

        PowerMockito.verifyStatic();
        Resource.readResources("whatever");
    }

}

class Resource {
    public static void readResources(String someArgument) {
        throw new UnsupportedOperationException("meh!");
    }
}
