Kotlin Plugin

Improves pitest's support for Kotlin

This is a work in progress looking for someone to take over and progress it.

UPDATE - This plugin is not maintained. If you are interested in mutating kotlin a commercial plugin is now available from arcmutate.

https://docs.arcmutate.com/docs/kotlin.html

This offers a significantly better exeperience when mutating Kotlin than the plugin here, with support for inline functions and many other language features.

Usage

The plugin requires pitest 1.4.1 or later.

To activate the plugin it must be placed on the classpath of the pitest tool (not on the classpath of the project being mutated).

e.g for maven

    <plugins>
      <plugin>
        <groupId>org.pitest</groupId>
        <artifactId>pitest-maven</artifactId>
        <version>1.2.5</version>
        <dependencies>
          <dependency>
            <groupId>org.pitest</groupId>
            <artifactId>pitest-kotlin-plugin</artifactId>
            <version>0.1-SNAPSHOT</version>
          </dependency>
        </dependencies>

        <configuration>
blah
        </configuration>
      </plugin>
   </pluginsugin>

or for gradle

buildscript {
   repositories {
       mavenCentral()
   }
   configurations.maybeCreate("pitest")
   dependencies {
       classpath 'info.solidsoft.gradle.pitest:gradle-pitest-plugin:1.2.4'
       pitest 'org.pitest:pitest-kotlin-plugin:0.1-SNAPSHOT'
   }
}

apply plugin: "info.solidsoft.pitest"

pitest {
    pitestVersion = "1.3.2"
    targetClasses = ['our.base.package.*']  // by default "${project.group}.*"
}

See gradle-pitest-plugin documentation for more configuration options.

About

When the plugin is enabled pitest will avoid creating junk mutations in code that uses

• de structuring code
• null casts
• safe casts
• elvis operator
