Running a specific instrumentation unit test with Gradle

Question

Is there a way to run a specific Android instrumentation unit test using Gradle? I\'ve tried

gradle -Dtest.single=UnitTestName connectedInstrumentTest
         


        

Answer 1

Erdi's answer didn't work for me but I have a single parent for all my test classes so I was able to do this:

public abstract class BaseEspressoTest extends ActivityInstrumentationTestCase2 {
    //...
    @Override
    protected void runTest() throws Throwable {
        if(getClass().getSimpleName().equals("MyTestClassName")) {
            super.runTest();
        }
    }
    //...
}

This executes only MyTestClassName. We can extend it further to execute only specific test method (or methods):

public abstract class BaseEspressoTest extends ActivityInstrumentationTestCase2 {
    //...
    @Override
    protected void runTest() throws Throwable {
        if("MyTestClassName".equals(getClass().getSimpleName()) 
           && "testMethodName".equals(getName())) {
            super.runTest();
        }
    }
    //...
}
