所有睾丸开始时省略灰色仪器测试

Question

我发生了一个烦人的问题，其中一个工具测试类显示为灰色，当我开始所有测试（包androidTest）时，这个被省略（其他人开始就好了）。任何想法可能是什么原因？

@RunWith(AndroidJUnit4.class)
public class LoginActivityTest extends ActivityInstrumentationTestCase2<LoginActivity> {
@Rule
public ActivityTestRule<LoginActivity> mActivityRule =
        new ActivityTestRule<>(LoginActivity.class, true, false);

private MockWebServer server;

private LoginActivity loginActivity;

private SharedPreferences loginDetails;

public LoginActivityTest() {
    super(LoginActivity.class);
}

Instrumentation.ActivityMonitor giftListActivityMonitor;


@Before
public void setUp() throws Exception {
    super.setUp();

    // Create a MockWebServer. These are lean enough that you can create a new
    // instance for every unit test.
    server = new MockWebServer();
    // Start the server.
    server.start();

    injectInstrumentation(InstrumentationRegistry.getInstrumentation());


    loginDetails = getInstrumentation().getTargetContext().getSharedPreferences("login_details",
            Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = loginDetails.edit();
    editor.clear();
    editor.commit();

    KupMiConstans.BASE_URL = server.url("/").toString();

    loginActivity = this.getActivity();

    Instrumentation instrumentation = getInstrumentation();

    giftListActivityMonitor = instrumentation.addMonitor(GiftListActivity.class.getName(), null, false);

    new PrepareSingletons(getInstrumentation().getContext());
}

@Test
...

@Test
...


@After
public void tearDown() throws Exception {
    SharedPreferences loginDetails = getInstrumentation().getTargetContext().getSharedPreferences("login_details",
            Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = loginDetails.edit();
    editor.clear();
    editor.commit();
    try {
        server.shutdown();
    } catch (Exception e) {
    }
}

提前致谢！

那是愚蠢的。

显示灰色图标，因为类中的第一件事必须是默认构造函数。在第一次测试完全基于浓缩咖啡并且至少需要一个断言*之前，测试中省略了类。奇怪的是订单如此重要......
