gradle-scoverage

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

This has now been deployed to maven central.

Getting started

buildscript {
    repositories {
        mavenCentral()
        maven { url "https://oss.sonatype.org/content/groups/public" }
    }
    dependencies {
        classpath 'org.scoverage:gradle-scoverage:0.4.1-SNAPSHOT'
    }
}

apply plugin: org.scoverage.ScoveragePlugin

dependencies {
    scoverage 'org.scoverage:scalac-scoverage-plugin_2.11:0.99.5'
    compile 'org.scala-lang:scala-library:2.11.0'
}

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

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
}
