AndroidX Espresso 测试 : No tests were found and Empty test suite

Question

我正在尝试运行 src/androidTest，这是我使用 AndroidX 库的 Android 项目中的仪器测试，但我得到的是 No tests were found 错误和空测试套件 日志。

我已经检查了所有使用 AndroidX 库的示例和文档都在做同样的事情。

我已尝试根据以下链接设置 Edit Configurations https://stackoverflow.com/a/53715513/1826656但仍然没有运气。

我做错了什么吗？或缺少任何步骤？

请检查此图片是否为 Test Run log

MainActivityTest.java 代码:

import static androidx.test.espresso.Espresso.onView;
import static androidx.test.espresso.action.ViewActions.typeText;
import static androidx.test.espresso.assertion.ViewAssertions.matches;
import static androidx.test.espresso.matcher.ViewMatchers.isDisplayed;
import static androidx.test.espresso.matcher.ViewMatchers.withId;
import static androidx.test.espresso.matcher.ViewMatchers.withText;

@RunWith(AndroidJUnit4.class)
@LargeTest
public class MainActivityTest {

   @Rule
   ActivityTestRule mActivityRule = new ActivityTestRule<>(MainActivity.class, false, false);

   @Test
   public void checkViewsVisibility() {
     // verify the visibility of recycler view on screen
     onView(withId(R.id.record_list_rv)).check(matches(isDisplayed()));

     // verify the visibility of progressbar on screen
     onView(withId(R.id.progressBar)).check(matches(isDisplayed()));

     // verify the visibility of no data TextView on screen By default it should be GONE
     onView(withId(R.id.no_data_tv)).check(matches(isDisplayed()));

     onView(withId(R.id.no_data_tv)).check(matches(withText("No Data")));

     onView(withId(R.id.no_data_tv)).perform(typeText("No Data"));
   }
}

Gradle 文件依赖:

android {
    defaultConfig {
       testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunne"
    }

    testOptions {
        execution 'ANDROIDX_TEST_ORCHESTRATOR'
    }
}

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestUtil 'androidx.test:orchestrator:1.1.1'
    androidTestImplementation 'androidx.test.ext:junit:1.1.0'
    androidTestImplementation 'androidx.test:rules:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-contrib:3.1.1'
}

您的 defaultConfig 中有错字。应该是:

testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
