Android 测试getter方法失败

我想测试的类发布在下面的代码部分。我正在尝试测试“getSubscriberName”方法。 我编码的测试在下面的测试部分发布。但是在运行时，测试失败了，我收到了下面发布的错误

我在build.gradle中使用的依赖项发布在下面

请让我知道如何纠正错误以及为什么我会得到它

代码

public class ListViewModel {

private String mSubscriberName = null;

public ListViewModel(String subscriberName) {
    mSubscriberName = subscriberName;
}

public String getSubscriberName() {
    return mSubscriberName;
}

public void setSubscriberName(String name) {
    mSubscriberName = name;
}

}

}

测试：

public class ListViewModelTest {

@Mock
private ListViewModel mListViewModel = null;
@Rule
public MockitoRule mockitoRule = MockitoJUnit.rule();

@Before
public void setUp() throws Exception {
    mListViewModel = new ListViewModel("");
}

@Test
public void getSubscriberName() {
    ListViewModel spyListViewModel = spy(mListViewModel);
    when(spyListViewModel.getSubscriberName()).thenReturn("YXZ");

    String expectedSubscriberName = spyListViewModel.getSubscriberName();
    Assert.assertEquals(expectedSubscriberName, spyListViewModel.getSubscriberName());
}

}

尽量避免使用spy，因为它通过调用所有依赖类方法来进行实际调用，并使您的测试用例闻起来更香，请为下面的问题找到解决方案（我仍然按照您的代码使用spy）
