android - 测试在 Android 6.0 上通过但在 Android 8.0 上失败 - androidx.test.espresso.PerformException : Error performing 'single click

Question

安卓工作室 3.3

我有两个编辑字段和一个按钮。如果单击按钮但未填写所有字段而不是带有错误消息的 toast - Please, input all fields

这里是 app/build.gradle:

    ext.ESPRESSO_VERSION = '3.2.0-alpha02'
    androidTestCompile 'com.azimolabs.conditionwatcher:conditionwatcher:0.2'

    androidTestImplementation "androidx.test.espresso:espresso-core:$ESPRESSO_VERSION"
    androidTestImplementation "androidx.test.espresso:espresso-intents:$ESPRESSO_VERSION"
    androidTestImplementation "androidx.test.espresso:espresso-contrib:$ESPRESSO_VERSION"
    androidTestImplementation "androidx.test:rules:$ANDROIDX_TEST"
    androidTestImplementation "androidx.test:runner:$ANDROIDX_TEST"
    androidTestImplementation 'com.squareup.okhttp3:mockwebserver:3.8.0'

    testImplementation 'junit:junit:4.12'

此处布局:

            layout="@layout/progress_bar_layout"
            android:visibility="gone" />

    </androidx.constraintlayout.widget.ConstraintLayout>

</layout>

这里是 Espresso 的测试:

@Test
    fun onlyQuoteFill_buttonStart_click() {
        onView(withId(baseTextInputEditText)).perform(clearText())
        onView(withId(quoteTextInputEditText)).perform(typeText(QUOTE_TEST))
        onView(withId(startButton))
                .perform(click())
        onView(withText(please_input_all_fields)).inRoot(ToastMatcher())
                .check(matches(isDisplayed()))
    }

并且此测试成功通过 模拟器 Android 5.0、6.0、7.0

不错。

但是当我在模拟器 Android 8.0 上开始这个测试时，它失败并显示错误消息:

Answer 1

Indicates that an exception occurred while performing a ViewAction onthe UI thread.

A description of the ViewAction, the view being performed on and thecause are included in the error. Note: FailureHandlers can mutate theexception later to make it more user friendly.

This is generally not recoverable so it is thrown on theinstrumentation thread.
