In order to mock static methods for unit testing in Java we can either use PowerMock or we Can use mockStatic of Mockito. I already know that need to mock static method means code smell and I should refactor the original code but that is not possible as of now.
Sample Class to be Tested
public class classToBeTested{
//Some Code
public static String methodToBeTested() {
// Some Code
}
}
Testing Using Mockito-Inline (Mockito MockStatic)
public class TestClassToBeTested{
private MockedStatic<classToBeTested> mockedClassToBeTested;
@Test
public void testmethodToBeTested() {
mockedClassToBeTested =
Mockito.mockStatic(classToBeTested.class);
mockedClassToBeTested.when(classToBeTested::methodToBeTested)
.thenReturn("Some Value");
// extra code for testing
}
}
Testing Using PowerMock
public class TestClassToBeTested{
@Test
public void testmethodToBeTested() {
PowerMockito.mockStatic(classToBeTested.class);
when(classToBeTested.methodToBeTested())
.thenReturn("Some Value");
// extra code for testing
}
}
So which mocking technique is better mockito-inline one or power mockito. what is the difference between them? what do they do behind the scene to achieve this?
