How can I run a single test with gradle android

问题

I'm trying to run the tests with this line... but this launches all tests:

./gradlew -DconnectedAndroidTest.single=LandingActivityTests connectedAndroidTest

How can I launch a single test?

回答1:

you can run the single android test in two steps:

1. ./gradlew installDebugAndroidTest
2. adb shell am instrument -w -e class com.example.MyInstrumentationTest#testFoo com.example.test/android.support.test.runner.AndroidJUnitRunner

回答2:

Since Android Gradle plugin version 1.3.0 you can use

./gradlew -Pandroid.testInstrumentationRunnerArguments.class=your.package.LandingActivityTests connectedAndroidTest

回答3:

if you want to run just one test inside the class do something like

./gradlew -Pandroid.testInstrumentationRunnerArguments.class=my.app.package.register.RegisterEmailTest#can_register connectedAndroidTest

can_register is a method in a class RegisterEmailTest

NOTE: the package needs to reference where the class is otherwise it will not work.

Visit Testing
Sadly, gradle connectedAndroidTest task is not supporting all the arguments.
There is feature request for gradle team.
If you are using Android Studio, you can create Run Configuration that launches specific test via adb shell am instrument
