I have most of the test of my project in the AndroidTest folder instead of Test because they need to use a lot of Db methods and because my colleagues decided to put them there. Now I can't move them because they'll stop working. But I need to get the code coverage of said tests...

Is there any way to enable code coverage for test under AndroidTest folder? I've been looking but none of the solutions I found work for me.

Note that I also have some Espresso tests that I'd like to get coverage to if it is possible.

  • @UrielFrankel Hey thanks for the help, but I got stuck at trying to pull the coverage.ec file. It says it doesn't exist even tho I just copied and pasted the 'generated code coverage data to' filepath Commented Jan 14, 2018 at 13:32
  • you meant adb pull /data/user/0/com.hellojacoco.app/files/coverage.ec ? Commented Jan 14, 2018 at 13:58
  • Yes, it says adb: error: remote object 'data/user/0/com.patan.gimnasio/files/coverage.ec' does not exist Commented Jan 14, 2018 at 14:41
  • @UrielFrankel do you know why? Commented Jan 15, 2018 at 9:33

I got a simple command for you. 

./gradlew createDebugCoverageReport

I just found out about this myself. The one problem is that it won't display anything in the Android Studio IDE, which is annoying, and I'm currently looking for a solution to. Instead, it'll instead create a JaCoCo report in the /app/build/reports/coverage/debug/ folder. I don't know if this'll also pick up espresso tests because I haven't messed with those yet.

Anyway, hope that helped.

The system cannot find the file specified
"gradlew createDebugCoverageReport" worked from the run anything (ctrl-ctrl) window
That folder does not exist after I ran the command
