run single integration test with gradle

Question

I'm trying to run a single integration tests using gradle's -Dtest.single flag. I have added another source set, src/integrationTest and put the tests in there. I have an integration test task

task integrationTests(type: Test) {
    dependsOn 'assemble', 'integrationTestClasses'    
    testClassesDir = sourceSets.integrationTest.output.classesDir
    classpath = sourceSets.integrationTest.runtimeClasspath
}

This runs fine, but if I try to run a single test it tells me it cannot find a matching test. I don't want to have to run every integration test each time I am writing a new one. Is there a way to do this?

Answer 1

The correct syntax is:

gradle testTaskName -DtestTaskName.single=...

In this case:

gradle integrationTest -DintegrationTest.single=...

Answer 2

Since Gradle 1.10 you can write:

 //select specific test method
gradle test --tests org.gradle.SomeTest.someFeature

//select specific test class
gradle test --tests org.gradle.SomeTest

//select all tests from package
gradle test --tests org.gradle.internal*

//select all ui test methods from integration tests by naming convention
gradle test --tests *IntegTest*ui*

//selecting tests from different test tasks
gradle test --tests *UiTest integTest --tests *WebTest*ui
