Separating tests from integration tests with Gradle

test.gradle

// Usage: gradlew [-Dtest.type=all|unit|integration] test

test {
    String testType = System.properties['test.type']
    if (testType == 'integration') {
        include '**/*IntegrationTest.*'
        include '**/*IntegrationSpec.*'
    } else if (testType == 'unit') {
        include '**/*Test.*'
        include '**/*Spec.*'
        exclude '**/*IntegrationTest.*'
        exclude '**/*IntegrationSpec.*'
    } else if (testType == 'all') {
        include '**/*Test.*'
        include '**/*Spec.*'
    } else {
        //Default to unit
        include '**/*Test.*'
        include '**/*Spec.*'
        exclude '**/*IntegrationTest.*'
        exclude '**/*IntegrationSpec.*'
    }
}

// Usage: gradlew integrationTest
task integrationTest(type: Test, description: 'Runs the integration tests', group: 'Verification') {
    include '**/*IntegrationTest.*'
    include '**/*IntegrationSpec.*'
}
