测试覆盖率报告不是使用java.io.IOException生成的

时间：2019-02-19 05:26:56

标签： android android-espresso

我正在Android应用上运行覆盖任务。我在build.gradle文件中添加了必要的命令testCoverageEnabled = true。我可以在./gradlew任务列表中看到任务createMockDebugAndroidTestCoverageReport。我执行了createMockDebugAndroidTestCoverageReport任务，并在控制台上收到以下错误：

* What went wrong:
Execution failed for task ':myAppApplication:createMockDebugAndroidTestCoverageReport'.
> java.io.IOException: No coverage data to process in directory '/Users/aaa.bbb/Documents/myApp-android/myAppApplication/build/outputs/code-coverage/connected/flavors/MOCK'

当我检查此路径时，它为空。

调试日志代码段是：

当我检查以下路径时：/Users/aaa.bbb/Documents/myApp-android/myAppApplication/build/reports/coverage/mock/debug在我的本地计算机上（我有Android Studio的地方） 它是空的。因此，我认为，此路径中没有数据可以处理覆盖率。
但是，当我看到设备（ddms）登录上面的调试代码片段时，我可以看到coverageFilePath = /data/data/com.chn.myApp/coverage_data/，并且当我在设备上检查此路径时，它确实不存在。 （com.chn.myApp文件夹不存在）。另外，我看不到此文件夹的删除命令，因此作为退出过程的一部分，该文件夹从设备中删除的可能性不大。因此，我想这应该是设备上未生成覆盖率报告的问题，但不确定为什么不创建此文件夹（设备上存储覆盖率信息的文件夹）。我正在使用Android模拟器。

任何指导表示赞赏！

我知道已经晚了。但是我遇到了同样的问题，我相信其他人也会遇到同样的问题。

我想您正在关注Google的文档并使用ANDROIDX_TEST_ORCHESTRATOR：

https://developer.android.com/training/testing/junit-runner.html#using-android-test-orchestrator

如果是，则IOException是Google在ANDROIDX_TEST_ORCHESTRATOR中的错误

https://issuetracker.google.com/issues/72758547

我所做的只是发表评论

//execution 'ANDROIDX_TEST_ORCHESTRATOR'

它应该能够生成代码覆盖率。

希望这会有所帮助

似乎Google修复了Android Gradle插件3.2.0-alpha17中的问题。

使用com.android.tools.build:gradle:4.1.1 distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip

ANDROIDX_TEST_ORCHESTRATOR起作用。

答案 1 :(得分：4)

我发现将Gradle版本降级为6.3可解决此问题。

答案 2 :(得分：0)

尝试运行createMockDebugAndroidTestCoverageReport，然后运行connectedMockDebugAndroidTest，而不是jacocoTestReport：

$ ./gradlew :myAppApplication:connectedMockDebugAndroidTest
$ ./gradlew :myAppApplication:jacocoTestReport
