PowerMockRule

Using AI Code Generation

1I have a class that I want to test, but it has a static method. I want to use PowerMock to mock the static method, but I can't get PowerMock to work with JUnit 5. I've tried using the PowerMockRunner and PowerMockRunnerDelegate annotations, but they don't work. I've also tried using the PowerMockRule, but I can't get that to work either. I've also tried using the PowerMockito.mockStatic() method, but I can't get that to work either. Here's the code I'm using:2@RunWith(PowerMockRunner.class)3@PowerMockRunnerDelegate(JUnit4.class)4public class LargeMethodTest {5    public PowerMockRule rule = new PowerMockRule();6    public void testLargeMethod() {7        PowerMockito.mockStatic(LargeMethod.class);8        PowerMockito.when(LargeMethod.largeMethod()).thenReturn(1);9        assertEquals(1, LargeMethod.largeMethod());10    }11}
