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* 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'
当我检查这条路径时，它是空的。

当我检查这条路径时： /Users/aaa.bbb/Documents/myApp-android/myAppApplication/build/reports/coverage/mock/debug 在我的本地机器上（我有 Android Studio）
它是空的。所以，我认为，这条路径中没有数据来处理覆盖率。
但是，当我在上面的调试片段中看到设备 (ddms) 日志时，我可以看到 coverageFilePath = /data/data/com.chn.myApp/coverage_data/ ，当我检查设备上的这条路径时，它确实不存在。 （com.chn.myApp 文件夹不存在）。此外，我看不到该文件夹的删除命令，因此该文件夹不可能作为退出过程的一部分从设备中删除。所以，我想，这应该是设备上未生成覆盖率报告的问题。但不确定为什么未创建此文件夹（覆盖率信息存储在设备上的位置）。我正在使用 Android 模拟器。
任何指导表示赞赏！
我知道来晚了。但我遇到了同样的问题，我相信其他人可能会看到同样的问题。
我想你正在关注谷歌的文档并使用
ANDROIDX_TEST_ORCHESTRATORhttps://developer.android.com/training/testing/junit-runner.html#using-android-test-orchestrator
如果你是，那么 IOException 是
ANDROIDX_TEST_ORCHESTRATORhttps://issuetracker.google.com/issues/72758547
我所做的只是评论
//execution 'ANDROIDX_TEST_ORCHESTRATOR'它应该能够生成代码覆盖率。
希望这有帮助

谷歌似乎在 Android Gradle 插件 3.2.0-alpha17 中修复了这个问题。

与
com.android.tools.build:gradle:4.1.1distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zipANDROIDX_TEST_ORCHESTRATOR 有效。
我发现将 Gradle 版本降级到 6.3 可以解决这个问题。
而不是
createMockDebugAndroidTestCoverageReportconnectedMockDebugAndroidTestjacocoTestReport$ ./gradlew :myAppApplication:connectedMockDebugAndroidTest
$ ./gradlew :myAppApplication:jacocoTestReport
确实如之前的答案所暗示的那样，问题是由
ANDROIDX_TEST_ORCHESTRATOR发生这种情况是因为以下内容删除了覆盖率数据：
testInstrumentationRunnerArguments clearPackageData: 'true'
这可以通过添加来解决：
android {
..
defaultConfig {
testInstrumentationRunnerArguments useTestStorageService: 'true'
..
}
}
dependencies {
androidTestUtil "androidx.test.services:test-services:$android_test_services_version"
..
}
