PowerMock抛出java.lang.ExceptionInInitializerError

131

HomJie：

我正在使用Powermock + Mockito2 + JUnit4对一个类进行单元测试。

当我尝试跑步时ApiCreatorFacadeImplTest.java，它不起作用并抛出java.lang.ExceptionInInitializerError。我不知道该如何解决。谁能指出我在犯什么错误？

import static org.powermock.api.mockito.PowerMockito.mock;

@RunWith(PowerMockRunner.class)
@PrepareForTest({HttpUtil.class})
public class ApiCreatorFacadeImplTest {

    private ServiceVersionFacade serviceVersionFacade;
    private ServiceFacade serviceFacade;

    private ApiCreatorFacadeImpl apiCreatorService;

    @Before
    public void setUp() {
        apiCreatorService = new ApiCreatorFacadeImpl();
        // mock ApiCreatorFacadeImpl fields
        serviceVersionFacade = mock(ServiceVersionFacade.class);
        serviceFacade = mock(ServiceFacade.class);
        // inject fields to apiCreatorService
        Whitebox.setInternalState(apiCreatorService, "serviceVersionFacade", serviceVersionFacade);
        Whitebox.setInternalState(apiCreatorService, "serviceFacade", serviceFacade);
    }

    @Test
    public void createHsfTypeApi() {
        // do nothing
    }

    @Test
    public void getApiTestParam() {
        // do nothing
    }
}

可能的原因是Mockito的版本Powermockito发生冲突。您能否检查一下mockito的受支持版本Powermockito。您可以查看此页面。
