How to run a single unit test using gradle wrapper 2.2.1 from command line

Question

Using Android studio with gradle wrapper version 2.2.1, I am trying to run all the tests in one single test class, as well as a specific test inside that class and have tried using:

./gradlew  test --tests DownloadsActivityTest

like the documentation suggests, as well as

-DandroidTest.single=DownloadsActivityTest

But neither of these versions work.

How do I run a single test class, and a single test from the command line using the gradle wrapper?

 ./gradlew --version

It's not clear if you are running _local_ or _instrumentation_ tests. If you are talking about instrumentation tests then this may be a duplicate of https://stackoverflow.com/q/19565857/1650674 — tir38, Feb 06 '20 at 00:12

To only run instrumentation tests (androidTests) in a specific test class, execute:

./gradlew app:connectedAndroidTest -Pandroid.testInstrumentationRunnerArguments.class=com.example.android.testing.blueprint.ui.espresso.EspressoTest

To only run local tests ("unit", JVM tests) in a specific test class or package execute:

./gradlew :app:testDebugUnitTest --tests "com.example.android.testing.blueprint.unit.integrationTests.*"

./gradlew :<module name>:test<CapitalCasedBuildVariant> --tests "<Test name pattern>"

It is important to specify the module name where the test lives, otherwise, when gradle builds dependent modules, it will attempt to test them, and might fail because none of the tests fit the test pattern:

No tests found for given includes: [FooTest]

Also, unless you specify the fully-qualified-name (FQN) of the test, your test name pattern should start with a *.

In my case, I have a module named app and a variant named localDebug, and I wanted to test FooTest, so I ran:

./gradlew :app:testLocalDebug --tests "*FooTest"

This works for unit tests, not instrumentation tests. – Jose Alcérreca Dec 06 '16 at 12:59 — Jose Alcérreca, Dec 06 '16 at 12:59

This is supported in Android Studio 1.1, using the Android Gradle plugin v1.1.0.

The Android Gradle plugin, as of 1.0.0, doesn't have support for running single Android tests. The feature request for it is filed at https://code.google.com/p/android/issues/detail?id=74196.

I know that better test support in general is very high on the post-1.0 priority list, but I can't say with any certainty when this will be implemented.
