Running android unit tests from the command line?

Question

I'm trying to run unit tests on the android platform in accordance with tutorial. Say, for example, I want to run tests for Email application. I open /apps/Email/tests/AndroidManifest.xml file, look for the <manifest> element, and look at the package attribute, which is com.android.email.tests, and in the <instrumentation> element I look at the android:name attribute, which is android.test.InstrumentationTestRunner. Now I open the console, and run

$ . build/envsetup.sh
$ lunch 1
$ adb shell am instrument -w com.android.email.tests/android.test.InstrumentationTestRunner

But that fails:

INSTRUMENTATION_STATUS: id=ActivityManagerService
android.util.AndroidException: INSTRUMENTATION_FAILED: com.android.email.tests/android.test.InstrumentationTestRunner
INSTRUMENTATION_STATUS: Error=Unable to find instrumentation info for: ComponentInfo{com.android.email.tests/android.test.InstrumentationTestRunner}

So.. What am I doing wrong?

Answer 1

Please run python development/testrunner/runtest.py email

and then you will see it works :).

Basically you do not have com.android.email.tests package installed.

You can see what is available for instrumentation

pm list instrumentation

And you should see

instrumentation:com.android.email.tests/android.test.InstrumentationTestRunner (target=com.android.email)

And when doing

pm list packages

package:com.android.email

package:com.android.email.tests

You may need to setup a test project with the android create test-project command first. Check this page on the Android Dev site: Testing In Other IDE's for more info. I've used this method to enable command line testing with ant.
