Adding an additional test suite to Gradle

Question

I am attempting to add Gradle (1.4) to an existing project that has multiple test suites. The standard unit test located in src/test/java ran successfully, but I am having trouble setting up a task to run the JUnit test located in src/integration-test/java.

When I run gradle intTest I get several cannot find symbol errors for classes in src/main. This leads me to believe that the dependencies are not set up correctly. How do I setup intTest so that it will run my JUnit integration tests?

build.gradle

apply plugin: 'java'

sourceCompatibility = JavaVersion.VERSION_1_6

sourceSets {
    integration {
        java {
            srcDir 'src/integration-test/java'
        }
        resources {
            srcDir 'src/integration-test/resources'
        }
    }
}

dependencies {
    compile(group: 'org.springframework', name: 'spring', version: '3.0.7')

    testCompile(group: 'junit', name: 'junit', version: '4.+')
    testCompile(group: 'org.hamcrest', name: 'hamcrest-all', version: '1.+')
    testCompile(group: 'org.mockito', name: 'mockito-all', version: '1.+')
    testCompile(group: 'org.springframework', name: 'spring-test', version: '3.0.7.RELEASE')

    integrationCompile(group: 'junit', name: 'junit', version: '4.+')
    integrationCompile(group: 'org.hamcrest', name: 'hamcrest-all', version: '1.+')
    integrationCompile(group: 'org.mockito', name: 'mockito-all', version: '1.+')
    integrationCompile(group: 'org.springframework', name: 'spring-test', version: '3.0.7.RELEASE')
}


task intTest(type: Test) {
    testClassesDir = sourceSets.integration.output.classesDir
    classpath += sourceSets.integration.runtimeClasspath
}

Details: Gradle 1.4

Solution: I had not set the compile classpath for the integration test source set (see below). In my I code I set the compile class path to sourceSets.test.runtimeClasspath so that I don't have the duplicate dependencies for "integrationCompile"

sourceSets {
    integrationTest {
        java {
            srcDir 'src/integration-test/java'
        }
        resources {
            srcDir 'src/integration-test/resources'
        }
        compileClasspath += sourceSets.main.runtimeClasspath
    }
}

Answer 1

the "integration" sourceSet has not configured its compile and runtime classpath. That's why it can't find the classes from your main sourceset. you can configure the compile and runtime classpath in the following way:

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

Answer 2

In most cases you want to use the same dependencies as your unit tests as well as some new ones. This will add the dependencies of your unit tests on top of the existing ones for integration tests (if any).

sourceSets {
    integrationTest {
        compileClasspath += sourceSets.test.compileClasspath
        runtimeClasspath += sourceSets.test.runtimeClasspath
    }
}
