Android浓缩咖啡测试：java.lang.TypeNotPresentException:类型org/powermock/modules/junit4/PowerMockRunner不存在

我试图在Android Espresso测试用例上使用Powermock来模拟静态方法，但我收到了这个错误

我的测试使用AndroidJUnit4.class Runner运行良好，我可以使用PowerMockRunner编译它们，此错误仅在运行时发生。我的应用程序是多索引的

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(AndroidJUnit4.class)
@PrepareForTest(RestClientFactory.class)
public class IgorLoginGoogleDemaisTest extends ActivityInstrumentationTestCase2<MainCacs>
{
...
    @Test
    public void test1_ErroDeConexaoAoLogar() throws NoSuchFieldException, IllegalAccessException
    {
        ....
        PowerMockito.mockStatic(RestClientFactory.class);
        PowerMockito.when(RestClientFactory.makeClient(UsuarioServicesClient.class, Mockito.any(Context.class))).thenThrow(new IOException("Erro de rede"));
        ....
    }
}

我试图将类名放入multidex.keep文件中，但没有成功

我该怎么修呢？

你好，我。。。你能让它工作吗？还没有：-（我不得不使用其他方法进行测试，而没有PowerMock@IgorRegis你能分享一下你的方法吗？
