Hi guys, I am investigating code-coverage for our Android app. built with Gradle and Android Studio.
I need code-coverage reports in two situations: during manual tests, and during automated tests built with our Appium suite. I need to get a proof-of-concept that JaCoCo can indeed do code coverage in this case. Given that we need coverage for Appium and manual tests, I believe offline-instrumentation with JaCoCo is what I need. I have succeeded in creating an instrumented APK. But when I run the app manually, I keep seeing errors in the logcat W/System.err: java.io.FileNotFoundException: /jacoco.exec: open failed: EROFS (Read-only file system) >From JaCoCo docs as well as general Googling, I understand that Jacoco needs >to know where to store the jacoco.exec file - and that I need to package a >jacoco-agent.properties (containing a destfile property) with the APK. I have tried putting jacoco-agent.properties in the "assets" folder of my app - it was packaged into the APK properly, but did not seem to have any effect (i.e Jacoco failed as usual) I tried putting it inside res - it did not get packaged into the APK. I tried res/raw and hit the error about a dash in the filename. I am at my wit's end, and would really appreciate help. How do I package jacoco-agent.properties using my Gradle build into the APK, so that JaCoCo will read it? -- You received this message because you are subscribed to the Google Groups "JaCoCo and EclEmma Users" group.
