I am trying to check my code coverage for a test case that I wrote in Kotlin. When I execute ./gradlew createDebugCoverageReport --info
, my coverage.ec file is empty and my reports indicate that I have 0% coverage. Please note, the test cases are 100% successful. Can anyone think of any reasons my coverage.ec file keeps returning 0 bytes?
I have searched everywhere with no luck.
