即使在添加 @PrepareForTest 之后，Mockito 也会要求为该类添加 @PrepareForTest

The class ExternalClass not prepared for test. To prepare this class, add class to the '@PrepareForTest' annotation. In case if you don't use this annotation, add the annotation on class or method level.

请帮我指出我使用 @PrepareForTest

@RunWith(PowerMockRunner.class)
@PrepareForTest(ExternalClass.class)
public class xyzTest {  
    @Mock
    private RestTemplate restTemplate;

    @Mock
    private TestClass testClass;

    @BeforeClass
    private void setUpBeforeClass() {
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void testSuccessCase() {
        Boolean mockResponse = true;
        ResponseEntity<Boolean> response = new ResponseEntity<Boolean>(mockResponse, HttpStatus.OK);
        SomeClass someClass = new SomeClass("test", "1.0.0", "someUrl", "someMetaData");

        PowerMockito.mockStatic(ExternalClass.class);

        Mockito.when(restTemplate.postForEntity(any(String.class), any(String.class), eq(Boolean.class))).thenReturn(response);
        Mockito.when(ExternalClass.getSomeClass(any(String.class))).thenReturn(someClass);

        Boolean result = testClass.someMethod("test");

        Assert.isTrue(result);
        Mockito.verify(restTemplate, times(1)).postForObject(any(String.class), any(String.class), any());
    }
}

推荐答案

确保将 @RunWith(PowerMockRunner.class) 也添加到类的顶部.
