Pitest not running with Kotlintest tests


I'm using kotlintest in my projects and I want to run mutation testing with pitest.

Already tried using pitest alone and with junit5 plugin, but the result is always:

Found  0 tests


================================================================================
- Statistics
================================================================================
>> Generated 610 mutations Killed 0 (0%)
>> Ran 0 tests (0 tests per mutation)

I'm using:

I know kotlintest supports pitest since v3.3.0 (according here) but I don't know how to make it work.

Any ideas how to make it run properly?

Thanks!


Solution

  • I was able to crack it

    For reference see "PIT test-plugins support" section in gradle pitest plugin documentation

    First you need to set up your buildscript like this:

    buildscript {
       repositories {
           mavenCentral()
       }
       configurations.maybeCreate('pitest')
       dependencies {
           classpath 'info.solidsoft.gradle.pitest:gradle-pitest-plugin:1.4.5'
           pitest "io.kotlintest:kotlintest-plugins-pitest:3.4.2"
       }
    }
    

    Then you should set PIT plugin name in pitest block

    pitest {
        testPlugin = 'KotlinTest'
        // rest of your pitest configuration
    }
    

    After that it should work. Hope this helps!
