Add provided dependency to test classpath using Gradle

I’ve provided dependency scope configured like below. My problem is, the provided dependencies are not visible during runtime in tests. How can I configure this to keep the dependencies provided but available on the test classpath?

apply plugin: 'java'

configurations {
    provided
}

sourceSets {
    main {
        compileClasspath += configurations.provided
    }
}

dependencies {
    provided 'com.google.guava:guava:18.0'
    provided 'org.apache.commons:commons-lang3:3.3.2'

    // Tests
    testCompile 'junit:junit:4.11'
    testCompile 'org.assertj:assertj-core:1.7.0'

    // Additional test compile dependencies
    testCompile 'joda-time:joda-time:2.2'
}

One solution is to add the dependency like the joda-time library with testCompile scope, but I don’t want to duplicate any entries. I’m sure it can be achieved with proper configuration.

Answer

Two ways to do this. First, have the testRuntime configuration extend from provided.

configurations {
    provided
    testRuntime.extendsFrom(provided)
}

Second, you could add the provided configuration to the classpath of your test task.

test {
    classpath += configurations.provided
}
