'createDebugAndroidTestCoverageReport'引发错误-未找到测试

Question

我正在尝试运行'createDebugAndroidTestCoverageReport'，但是当我在build.gradle中更改以下选项时，它会向我抛出错误

defaultConfig{
//from
testInstrumentationRunner 'android.support.test.runner.AndroidJUnitRunner'
//to
testInstrumentationRunner 'com.test.modules.runner.JunitTestSuite'
}

错误： com.android.builder.testing.ConnectedDevice>找不到测试。[rooted-device（AVD）-4.4.2]失败 找不到测试。这通常意味着您的测试类的格式不符合测试跑步者期望的形式（例如，不要从TestCase继承或缺少@Test批注）。

  

任务：app：connectedDebugAndroidTest失败

JunitTestSuite如下：

@RunWith(Suite.class)

@Suite.SuiteClasses({
        Test1.class,
        Test2.class

})

public class JunitTestSuite {
}

Test1.class

@LargeTest
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
@RunWith(AndroidJUnit4.class)
public class Test1 {

    public static ViewInteraction replacePassword;
    public static ViewInteraction clickLoginButton;
    public static ViewInteraction clickCountOnHomePage;
    public static ViewInteraction clickOnCounts;
    public static ViewInteraction clickOnFixture;

    @Rule
    public ActivityTestRule<LoginActivity> mActivityTestRule = new ActivityTestRule<>(LoginActivity.class);

    @Test
    public void a_amcount() {

        CommonUtil.amTime();

        WaitForUIUpdate.waifForWithId(R.id.username, null);
        WaitForUIUpdate.waifForWithId(R.id.username_input_layout, null);
        onView(withId(R.id.username)).check(ViewAssertions.matches(isDisplayed()));
        onView(withId(R.id.username_input_layout)).check(ViewAssertions.matches(isDisplayed()));
}}
