Kover Gate Report

koverGate Report Skill

After writing or modifying tests in a module, check coverage gaps and close them.

Steps

1. Run the coverage gate task for the module you changed:

   ./gradlew :<module-name>:koverGateReport
   

   Replace <module-name> with the Gradle module path (e.g., :app, :core:data).

2. Read the JSON gap report:

   <module-name>/build/reports/kover/gap-report.json
   

3. Interpret results:

   • If "passed": true — coverage requirements are met. Done.
   • If "passed": false — examine the files array. Each entry lists:
     • uncoveredLines: line numbers with no coverage (mi > 0)
     • missedBranchLines: line numbers with partial branch coverage (mb > 0)

4. Write targeted tests to cover the identified lines and branches. Focus on:

   • The specific line numbers listed in uncoveredLines
   • The conditional paths at lines listed in missedBranchLines

5. Re-run the task to confirm gaps are closed:

   ./gradlew :<module-name>:koverGateReport
   

   Repeat until "passed": true.

Notes

• Adjust thresholds in your module's build.gradle.kts via the koverGate {} block if 100% is not the right target for a specific metric.
• Disable metrics that don't apply with disabledMetrics.set(setOf(CoverageMetric.BRANCH)).
• The JSON report is always written (even on pass) at build/reports/kover/gap-report.json.
