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

This works if you're using an instrumentationTestRunner:

./gradlew test -Pandroid.testInstrumentationRunnerArguments.class=.YourClassName

Using gradle 2.10 and android gradle plugin 2.0.0-beta2.

Since you know what test(s) you want to run, you probably know which module / flavor to use too. You can help Gradle out by specifying the exact module and Gradle task. So if your test is in the app module and you want to test the debug flavor:

./gradlew app:connectedDebugAndroidTest -Pandroid.testInstrumentationRunnerArguments.class=.YourClassName

You can get even more fancy with the tests_regex argument instead:

./gradlew app:connectedDebugAndroidTest -Pandroid.testInstrumentationRunnerArguments.tests_regex=PartialClassName*
./gradlew app:connectedDebugAndroidTest -Pandroid.testInstrumentationRunnerArguments.tests_regex=partialMethodName*
