测试覆盖率报告不是使用java.io.IOException生成的 [英] Test coverage report is not generated with java.io.IOException
本文介绍了测试覆盖率报告不是使用java.io.IOException生成的的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在Android应用程序上运行覆盖任务.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:
I am running a coverage task on Android app. I have added the necessary command testCoverageEnabled = true in build.gradle file. I can see the task createMockDebugAndroidTestCoverageReport in ./gradlew task list. I executed the tasks createMockDebugAndroidTestCoverageReport and got the following error on the console:
* 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.
When I checked this path, its empty.

23:42:34.713 [DEBUG] [org.gradle.launcher.daemon.client.DaemonClientConnection] thread 1: connection stop
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)登录上述调试代码段时，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，我看不到该文件夹的删除命令，因此在退出过程中没有机会从设备中删除该文件夹.因此，我想这应该是在设备上未生成覆盖率报告的问题，但是不确定为什么不创建此文件夹(在设备上存储覆盖率信息的文件夹).我正在使用Android模拟器.
When I checked this path: /Users/aaa.bbb/Documents/myApp-android/myAppApplication/build/reports/coverage/mock/debug on my local machine (where i have Android Studio)
Its empty. So, i think, there is no data in this path to process the coverage.
But, when i see the device (ddms) logs in the above debug snippet, i can see that the coverageFilePath = /data/data/com.chn.myApp/coverage_data/ , and when i check this path on the device, it does not exists. (the com.chn.myApp folder does not exists). Also, i could not see a remove command for this folder, so there is no chance that the folder is removed from device as part of the exit process. So, i guess, this should be an issue where the coverage report is not generated on the device.But not sure why this folder (where the coverage info is stored on the device) is not created. I am using Android emulator.
任何指导表示赞赏！
推荐答案
我知道来晚了.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.
I know it's late. But I encountered this same problem and I believe others might see the same problem.
我想您正在关注Google的文档，并使用 ANDROIDX_TEST_ORCHESTRATOR :
I suppose you're following google's document and use 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
If you are, the IOException is a google's bug in the ANDROIDX_TEST_ORCHESTRATOR
https://issuetracker.google.com/issues/72758547
我所做的只是发表评论
//执行'ANDROIDX_TEST_ORCHESTRATOR'
它应该能够生成代码覆盖率.
It should be able to generate code coverage.
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.
It seems google fixed the issue at Android Gradle plugin 3.2.0-alpha17.

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.
ANDROIDX_TEST_ORCHESTRATOR works.
这篇关于测试覆盖率报告不是使用java.io.IOException生成的的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
