测试类模板

@RunWith(PowerMockRunner.class)
@PrepareForTest({CollaboratorWithStaticMethods.class})
public class CollaboratorWithStaticMethodsTest {
    @Test
    public void testFirstMethod() {
    }
}

静态方式调用当前类的其他静态方法时，如何写单元测试

public static String forthMethod() {
        String str = firstMethod("John");
        return str + "Good morning!";
    }

@Test
public void testForthMethod() {
    PowerMockito.spy(CollaboratorWithStaticMethods.class);
    PowerMockito.when(CollaboratorWithStaticMethods.firstMethod(anyString())).thenReturn("test");
    String result = CollaboratorWithStaticMethods.forthMethod();
    Assert.assertEquals("testGood morning!", result);
}
