android jacoco coverage empty with gradle

Question

I\'m trying to make jacoco create a code coverage report for my android test project. I have the following in build.gradle:

apply plugin: \'com.android.appli         


        

Answer 1

I found a solution to same problem from Jacoco code coverage in Android Studio with flavors. It has example what to do in case coverage.ec is generated instead of testDebug.exec.

1. I created the jacocoTestReport task.

2. I executed $./gradlew createDebugCoverageReport which generates the coverage.ec file

3. After that I executed $./gradlew jacocoTestReport and that creates the HTML.
