testing - Gradle Test Dependency

Question

I have two projects, project A and Project B. Both are written in groovy and use gradle as their build system.

Project A requires project B. This holds for both the compile and test code.

How can I configure that the test classes of project A have access to the test classes of project B?

Answer 1

You can expose the test classes via a 'tests' configuration and then define a testCompile dependency on that configuration.

I have this block for all java projects, which jars all test code:

task testJar(type: Jar, dependsOn: testClasses) {
    baseName = "test-${project.archivesBaseName}"
    from sourceSets.test.output
}

configurations {
    tests
}

artifacts {
    tests testJar
}

Then when I have test code I want to access between projects I use

dependencies {
    testCompile project(path: ':aProject', configuration: 'tests')
}

This is for Java; I'm assuming it should work for groovy as well.
