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?

Solution 1

The correct syntax is:

gradle testTaskName -DtestTaskName.single=...

In this case:

gradle integrationTest -DintegrationTest.single=...

Solution 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

Solution 3

Just incase anyone is coming here looking for answers. This has been removed in gradle 5.0. Look for test.single in https://docs.gradle.org/current/userguide/upgrading_version_4.html

If you still wish to use a command line option in this style you should be able to use the --tests commandline param. See https://docs.gradle.org/current/userguide/java_testing.html#simple_name_pattern

$ ./gradlew integrationTest --tests=MyTest

When I try this, I get something like: $ gradlew -Dtest.single=SingleTest :subproject:test ... :buildSrc:test FAILED FAILURE: Build failed with an exception. What went wrong: Execution failed for task ':test'. Could not find matching test for pattern: SingleTest

[Peter Niederwieser]

Perhaps you don't have a test class with that name?

I found that -Dtest.single='foo' was ok on linux but failed on win due to the use of ' vs " or nothing. So, those choices may have impacts due to the shell used.

Actually, it should be -DintegrationTest.single=... (without the "s")

[Jacques Koorts]

Actually it should be -DintegrationTests.single=... because he named the task 'integrationTests' in his gradle file.

The embedded link nor comment mentions if this works for the integrationTest that the OP was asking about.
