推荐答案

解决方案

这似乎是 Android测试Codelab示例应用中记录的问题.

Solution

This appears to be an issue documented in the Android Testing Codelab sample app.

在Codelab示例 build.gradle 中，这被称为已知问题.

Within the Codelab sample build.gradle this is referred to as a known issue.

// Once https://issuetracker.google.com/127986458 is fixed this can be testImplementation
implementation "androidx.test:core:$androidXTestCoreVersion"

我将应用程序的依赖关系重构为testImplementation而不是androidTestImplementation.

I refactored my app's dependency to testImplementation instead of androidTestImplementation.

testImplementation 'androidx.test:core:1.2.0'
testImplementation 'androidx.test.ext:truth:1.2.0'
testImplementation 'com.google.truth:truth:0.44'

注意-Google文档 AndroidX Test的设置项目，以反映此问题，因为它目前指示开发人员使用androidTestImplementation.我已提交文档问题来解决此问题.

Note - The Google documentation Set up project for AndroidX Test should be updated to reflect this issue as it currently instructs the developer to use androidTestImplementation. I have filed a documentation issue to resolve this.
