I try to run a instrumentation test via "gradlew connectedAndroidTest". I get following error:
Tests on GT-I9305 - 4.3 failed: Instrumentation run failed due to 'java.lang.ClassNotFoundException'
com.android.builder.testing.ConnectedDevice > hasTests[GT-I9305 - 4.3] FAILED
No tests found.
:mobile:connectedAndroidTest FAILED
This is the output with --stacktrace option:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':mobile:connectedAndroidTest'.

Any idea?
I just found myself with the same problem, and resolved it by updating to espresso 2.0
Replace the testInstrumentationRunner in your build.gradle file
testInstrumentationRunner "com.google.android.apps.common.testing.testrunner.GoogleInstrumentationTestRunner
to
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
and update the new dependencies to 2.0
androidTestCompile files('lib/espresso-1.1.jar', 'lib/testrunner-1.1.jar', 'lib/testrunner-runtime-1.1.jar')
to
androidTestCompile 'com.android.support.test:testing-support-lib:0.1'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.0'
You also have to change the namespace in your tests, but you will notice when running them.
Full explanation: https://code.google.com/p/android-test-kit/wiki/EspressoSetupInstructions
Edit:
Seems I was too soon in answering, the answer I posted only fixed it on 5.0 devices. Below is what fixed it on older devices:
Exclude javax.inject from the new dependency by changing:
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.0'
to
androidTestCompile('com.android.support.test.espresso:espresso-core:2.0') {
exclude group: 'javax.inject'
}
source: Dagger code giving NoClassDefFoundError when Espresso Tests are run, normal run works fine
