Separating integration tests from unit tests in Android Studio

Question

I\'m trying to separate out integration tests in Android Studio 0.9.

I have added the following to the build file:

sourceSets {
    integrationTest {
            


        

Answer 1

I've done exactly this kind of separation in Gradle, but for a pure Java project, not Android. You are not specifying the classpath in source sets, which I think is the issue. Here's the relevant part of the build.gradle:

sourceSets {
    integration {
        java {
            compileClasspath += main.output + test.output
            runtimeClasspath += main.output + test.output
            srcDir file('src/integration/java')
        }
        resources {
            srcDir 'src/integration/resources'
        }
    }
}

configurations {
    integrationCompile.extendsFrom testCompile
    integrationRuntime.extendsFrom testRuntime
}

task integrationTest(group: "verification", type: Test) {
    testClassesDir = sourceSets.integration.output.classesDir
    classpath = sourceSets.integration.runtimeClasspath
}
integrationTest.dependsOn testClasses

IntelliJ idea picks up the folders under src/integration if they have the standard names (java, resources).

Answer 2

@sm4's answer works indeed for a Java module (with apply plugin: 'java'), but unfortunately not for Android application (apply plugin: 'com.android.application') nor Android library modules (apply plugin: com.android.library).

But I have found a workaround:
Create the folders for your integration tests:

src/integrationTest/java
src/integrationTest/res

Add the sourceSets for your new folders:

sourceSets {
    integrationTest {
        java {
            srcDir file('src/integrationTest/java')
        }
        res {
            srcDir file('src/integrationTest/res')
        }
    }
}

In a pure Java module the java folder would now turn green and the res folder icon would change. In an Android application/library module it does not.

Now create a product flavor identically named as the folder configured in the sourceSet, and it works!

productFlavors {
    integrationTest {
    }
}

And to put a cherry on top:

configurations {
    integrationTestCompile.extendsFrom testCompile
}
