Find out if an object is a mock or spy in Mockito

The need for it

[wp_ad_camp_5]

Finding out if an object is a mock or spy in Mockito may not (or never) be part of your usual automated unit tests but in some cases (advanced usage of JUnit/Mockito) you may need to determine its type.

Is Mock or Spy?

Below is a sample code to determine if an object is mock or spy in Mockito.

@Test
    public void test_dependencies_mock_or_spy() {

        // dependency1 is a mock object
        Assert.assertTrue(Mockito.mockingDetails(dependency1).isMock());

        // dependency1 is not a spy object
        Assert.assertFalse(Mockito.mockingDetails(dependency1).isSpy());

        // dependency2 is not a mock object
        Assert.assertTrue(Mockito.mockingDetails(dependency2).isMock());

        // dependency2 is a spy object
        Assert.assertTrue(Mockito.mockingDetails(dependency2).isSpy());

    }
