How can Kotlin operator functions be covered in test reports

Question

How can Kotlin operator functions be covered in test reports Since `kotlinx kover` does <https github com Kotlin kotlinx kover features|not support> instrumentation tests executed on Android device I am still using a Jacoco gradle task for generating code coverages In this case `operator fun` s signature is marked uncovered by Jacoco although the method body is being covered see screenshot How can I cover the method signature Would there be any workaround to cover it

Did you add unit tests for the suspend function afaik when running the jacoco report it takes the coverage for unit tests and not for the instrumented ones

Yes it is configured to merge execution data for both unit and instrumented tests More Info <https github com trustedshops public etrusted android trustbadge library blob 4893b6a6000f8873c0b9cfb6e93a0c315088be37 library build gradle kts L129|https github com trustedshops public etrusted android trustbadge library blob 48 93b6a6000f8873c0b9cfb6e93a0c315088be37 library build gradle kts>

I guess coverage is just for unit test

Ali Kabiri · Answer

< chanjungskim> Good point but that doesn t seem to be the case since the existing coverage is also coming from instrumented tests If it helps feel free to view clone the project here You can run all the tests with coverage from commandline using ```bundle exec fastlane test``` The HTML coverage file will be under following path ```library build mergedReportDir jacocoTestReport html index html```

Problems are Jacoco doesn t understand Kotlin magic giving an incorrect coverage for Kotlin classes Kover does understand Kotlin magic giving a correct coverage for Kotlin classes and Jacoco can parse Android execution tests end to end ui Espresso Barista younameit tests Kover cannot yet it s their target for 1 0 release parse Android execution tests

Thank you so much for clarifying the problem I wish there could also be a workaround for it slightly smiling face
