A plugin to enable the use of Scoverage in a gradle Scala project.

This has now been deployed to maven central.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'org.scoverage:gradle-scoverage:0.4.1'
    }
}

apply plugin: scoverage.ScoveragePlugin

dependencies {
    scoverage 'org.scoverage:scalac-scoverage-plugin_2.10:0.98.4'
    compile 'org.scala-lang:scala-library:2.10.1'
}

This creates an additional task testCoverage which will run tests against instrumented code

• instrumenting main scala code
• running JUnit tests against instrumented scala code
• failing the build on lack of coverage

Then launch command : gradle testScoverage or gradle checkScoverage

By default, when you launch gradle checkScoverage build fail if only 75% of project is covered by tests.

To configure it as you want, add this configuration :

checkScoverage {
    minimumLineRate = 0.5
}
