Espresso UI 测试已取消且没有错误消息

Question

这是我运行 UI 测试时的问题。

但 ExampleInstrumentedTest 正在运行。

这是我的测试文件，我已经注释掉所有内容，留下一个空函数

@RunWith(AndroidJUnit4ClassRunner::class)
class ExploreFragmentTest {

    @get: Rule
    val activityRule = ActivityScenarioRule(MainActivity::class.java)

    @Test
    fun test_isSearchButtonDisplayed() {
        //onView(withId(R.id.btn_search)).check(matches(isDisplayed()))
    }
}

这是我在 app/gradle 中的依赖项

    // AndroidX Test - Instrumented testing
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
    androidTestImplementation 'androidx.test:rules:1.4.0'
    androidTestImplementation 'androidx.test.espresso:espresso-contrib:3.4.0'

仍在寻找答案：如何查看实际的错误信息？？？

我们可以在错误反馈上做得更好吗？

Answer 1

我有同样的错误。

我用adb和logcat查看日志：adb logcat

我在日志中发现了这个错误：

java.lang.NoSuchMethodError: No static method registerDefaultInstance(Ljava/lang/Class;Lcom/google/protobuf/GeneratedMessageLite;)V in class Lcom/google/protobuf/GeneratedMessageLite; or its super classes (declaration of 'com.google.protobuf.GeneratedMessageLite' appears in /data/app/~~BuZ1RxiHRJybZNpyUcjGIw==/-xuI8WeeYUojtsn-ncVI-aw==/base.apk)

为了解决这个问题，我在我的build.gradle 文件中从androidx.test.espresso:espresso-contrib:3.4.0 中排除了protobuf-lite：

androidTestImplementation ("androidx.test.espresso:espresso-contrib:3.4.0") {
    exclude module: "protobuf-lite"
}

现在我的测试成功了！
