Jacoco with Robolectric and Gradle?

[Andreas]

Hey guys.

Thanks for the efforts in bringing Robolectric to Gradle!
It's all working well and I have Jacoco generating code coverage for Android, but having some issues with configuring Jacoco. This may or may not be related to Robolectric itself, but I suspect someone might know the answer.

I don't seem to be able to configure Jacoco for the Android module as I do for my Java modules. I need to define exclude patterns.

In a Java module, I simply define,
    test {
        jacoco {
            toolVersion = "0.6.3.201306030806"
            excludes = codeCoverageExclude.tokenize(',')
        }
    }

and Jacoco will exclude based on my exclude patterns.

However, for the Android module with Robolectric tests, it seems to ignore my attempts to configure Jacoco.

I have tried putting the jacoco closure both under "androidTest" and just "test", but neither works. As Jacoco actually is running and generating Jacoco exec files for the Android tests, it seems like it should be possible to configure it as well?

Any ideas?

(I'm using Gradle 1.11, Android Gradle plugin 0.9.2 and Robolectric Gradle plugin 0.9.4, running Gradle from command line)

Thanks, Andreas

Any success with this? I am trying to do the same thing, with no luck! :(

This is how we make it work at the moment (Gradle 1.11, Android Gradle plugin 0.10.0, Robolectric Gradle plugin 0.10.0):

apply plugin: 'jacoco'

// get class dirs for project dependencies

FileTree getJacocoClassDirs(List projects) {

    def classDirs = fileTree(dir: "${buildDir}/classes/debug", exclude: '**/R*.class')

    projects.each {

        def projBuildDir = project(it).buildDir

        classDirs += fileTree(dir: "${projBuildDir}/classes/release", exclude: '**/R*.class')

    }

    return classDirs

}

// get source dirs for project dependencies

FileCollection getJacocoSrcDirs(List projects) {

    Set srcDirs = android.sourceSets.main.java.srcDirs

    projects.each {

        def projDir = project(it).projectDir

        srcDirs.add("${projDir}/src") // assume that android main sourceSets is here

    }

    return files(srcDirs)

}

// generate coverage report for this project and all its project dependencies

task jacocoTestReport(type: JacocoReport, dependsOn: test) {

    reports {

        xml.enabled false

        csv.enabled false

        html.destination "${buildDir}/reports/coverage"

    }

    // TODO: automatically get project dependencies recursively

    def dependencies = [] // your gradle project dependencies go here

    classDirectories = getJacocoClassDirs(dependencies)

    sourceDirectories = getJacocoSrcDirs(dependencies)

    executionData = files("${buildDir}/jacoco/testDebug.exec")

}
