Android test code coverage, Eclipse

Is there a way to run unit tests for Android from Eclipse in a way that will instrument the code and measure test code coverage?

I'm looking for a simple way to find out which parts of my application aren't tested yet, fix the test cases and see if that helped.

I've been used EMMA (android already support it) for code coverage (and android-junit-report for test reports), here is a summary:

  • Create android project (or library)

android.bat update project -p project -n my_project -t android-16

cd project

ant emma clean debug

  • create a test project (linked to previous library)

android.bat update project --library ..\project -p project_Test -n project_Test -t

  • in case the main project is not a library

android.bat update project -m ..\project -p project_Test -n project_Test -t

ant emma clean debug install I ddidn't use 'test' since I want to run my own instrument

adb shell am instrument -e coverage true -e coverageFile sdcard/coverage.ec -w com..myproject.test/com.zutubi.android.junitreport.JUnitReportTestRunner

  • Pull files from device (emulator)

adb pull sdcard/junit-report.xml

adb pull sdcard/coverage.ec

  • Generate XML report (can also generate html report)

java -cp emma.jar emma report -r xml -in bin/coverage.em,coverage.ec

  • Generate HTML report (can also generate html report)

java -cp emma.jar emma report -r html -in bin/coverage.em,coverage.ec

  • Using Post-builds (Jenkins):

    • JUnit report XML
    • Emma Coverage report (give the coverage.xml as input)

Don't need the emma.jar into libs
