Playground Android project to test jacoco-report github action

Running Code Coverage at Module level

• The app module has multiple product flavors, and so it has 8 variants of coverage. To run code coverage for "prod" flavor with env dimension and "normal" flavor with api dimension for "debug" build type, run ./gradlew prodNormalDebugCoverage
• The math and text modules has only buildTypes, and so to get the coverage, run ./gradlew debugCoverage.
• You could run the ./gradlew coverAllVariants to generate code coverage reports for all variants supported in the app.

Running Code Coverage for entire project

• Choose the variants for each module that you want to run code coverage.
• Add them to the variants array in project.gradle.
• Either run the individual Coverage task for each variant, or just run ./gradlew coverAllVariants.
• Run ./gradlew allDebugCoverage.
• The unified report will be generated under ${rootDir}/build/reports/jacoco/
