Display Coverage % in Gitlab

[ybentlili]

Hello
I want to display the % of coverage in Gitlab.
I can get it by
grep -Eo "[0-9]+([.][0-9]+)%" path/to/report//index.html | head -1

But I don't know to display it in Gitlab as Coverage must be regular expression.

Thanks

In the script tag block of your job (Inside .gitlab-ci.yml) you can add one line after executing kover:
- cat path/to/report/index.html

Then you can add the regex in a coverage tagcoverage tag for the same job.

Until Kover provides an easy integration, here is particularly fragile way of doing this:

values=$(cat build/reports/kover/project-xml/report.xml | tail -7 | head -5 | grep 'INSTRUCTION' | cut -d ' ' -f 3,4 | sed 's/missed="//;s/" covered="/ /;s/"\/>//')
missed=$(<<<$values cut -d ' ' -f 1)
covered=$(<<<$values cut -d ' ' -f 2)
echo "Coverage $(($covered * 100 / ($covered + $missed)))%"

A simple way for Kover to make all of this unnecessary would be to provide a Gradle task similar to this:

$ ./gradlew koverStats
Instruction: 12%
Branch: 32%
Line: 15%
Method: 35%
Class: 80%

This command would also be useful for CLI users.

I liked the idea of CLOVIS-AI and integrated it as a gradle task

Still a bit hacky gradle task, maybe someone could improve on that

After that I'm using this gitlab coverage config
coverage: '/Type: INSTRUCTION .*?([\d\.]+)%/'

In case anyone interested in a Kotlin version of gradle task above(#229)

tasks.register("koverPrintMergedXmlCoverage") {
    val koverMergedXmlReport = tasks.named("koverMergedXmlReport")
    dependsOn(koverMergedXmlReport)
    doLast {
        //language=RegExp
        val regexp = """<counter type="INSTRUCTION" missed="(\d+)" covered="(\d+)"/>""".toRegex()
        koverMergedXmlReport.get().outputs.files.forEach { file ->
            // Read file by lines
            file.useLines { lines ->
                // Last line in file that matches regexp is the total coverage
                lines.last(regexp::containsMatchIn).let { line ->
                    // Found the match
                    regexp.find(line)?.let {
                        val missed = it.groupValues[1].toInt()
                        val covered = it.groupValues[2].toInt()
                        println("Total Code Coverage: ${covered * 100 / (missed + covered)}%")
                    }
                }
            }
        }
    }
}
