Question

我只是想开始使用Android Studio 3.2.1版中的“ Record Espresso测试”集成我的APP的一些基础测试。我可以记录测试。之后，Studio提示我，某些依赖项丢失了，是否应该添加它们。在这里，我选择是。 Gradle希望再次同步，并且该过程没有任何问题。如果我现在想运行其中一项测试，则构建过程开始并开始。失败了

Conflict with dependency 'androidx.annotation:annotation' in project ':app'. Resolved versions for app (1.0.0-rc01) and test app (1.0.0) differ. See https://d.android.com/r/tools/test-apk-dependency-conflicts.html for details.

我查看了提供的链接，但并没有真正让我更进一步。

有人能指导我正确的方向，我做错了什么吗？

由于30000个字符的限制，“ androidDependencies”的结果太长了，无法附加到我的问题中。

“ androidDependencies”的输出很大，因此这里是其链接。 Link to the file on my webserver

按照建议删除了“'com.google.gms：google-services：4.1.0'”，保持不变。

Answer 1

删除for(int i=0; i<ar.length; i++) { if(ar[i] % 2 == 0) continue; for(int j=i; j<ar.length; j++) { if(ar[j] % 2 == 0) continue; if(ar[i] > ar[j]) { int temp = ar[i]; ar[i] = ar[j]; ar[j] = temp; } }，这是完全错误的。

问题可能是您将implementation 'com.google.gms:google-services:4.1.0'与com.android.support一起使用并且androidx.test是testInstrumentationRunner = "android.support.test.runner.AndroidJUnitRunner"的错误测试运行程序。

app没有单一的androidx.test依赖关系-除了androidx目录中的某些.jar之外。运行libs来查看不合算的./gradlew app:dependencies > ./dependencies.txt && gedit ./dependencies.txt的来源。

Answer 2

就这样，我可以将其标记为完成：

我已经在Studio中使用重构到androidx了。只需让它再次运行，它又发现了11个要转换的零件，现在就开始测试。我假设Studio中的Recording Espresso Test功能没有通过喷射转换为androidx，因此会产生冲突的配置。

所以现在我可以记录Espresso测试并进行编译。

感谢您的帮助。

Espresso测试失败的原因是“与依赖项冲突”
