Since I migrated a project to Android Studio, I am getting following error when I want to run my tests:

Process finished with exit code 255

My testclass looks like this:

@Config(manifest = C.MANIFEST, emulateSdk = 18, reportSdk = 18)
@RunWith(RobolectricTestRunner.class)
public class JSONDataHelperTest {...}

Any ideas?

to less informations. which android studio version have you? which plugin do you use to support robolectric in andorid studio? how looks you project structure? – nenick
@nenick ok, added more info – stoefln
@stoefln Why do you have so many "hacks" in your build.gradle? – Jared Burrows
@JaredBurrows because I don't know how to include the classes of my main module instead. The test classes are in a separate library module. Usually libraries don't reference the main app. I copied the code, but I really wonder why the whole setup is so damn complicated. I spent hours (almost days) of debugging. Kind of frustrating. – stoefln
@stoefln I just found where you got that build.gradle. I understand that robolectric + latest android gradle build tools is difficult to setup. Google needs to provide either support for Robolectric or their own version of Robolectric. – Jared Burrows

The error message looks like that no resources are found ;) explicit the content from your string.xml

Lets start ..

com.github.jcandksolutions.gradle:android-unit-test:2.1.1

This plugin support explicit to have your tests in the same module

  • app
    • src/main/java
    • src/test/java

For extra test module you must use a different plugin to support robolectric. You can also have extra test modules with the jcandksolutions plugin but this would be more a application->library relationship instead of test->application/library.

testCompile androidModule.android.applicationVariants.toList().first().javaCompile.classpath testCompile androidModule.android.applicationVariants.toList().first().javaCompile.outputs.files testCompile files(androidModule.plugins.findPlugin("com.android.application").getBootClasspath())

Nice try but I guess this will not give you all classes and resources. This lines aren't necessary eval which plugin you will use.

What now ...

Questions is how should you project structure look? Is it important for you to have tests in a separate module?

With separated test module use https://github.com/novoda/gradle-android-test-plugin. For one module stay with jcandksolutions or you could also try the plugin from robolectric team https://github.com/robolectric/robolectric-gradle-plugin

All plugins have examples how to use them:

For 1.0 version from Android Studio I recommend jcandksolutions, because of much better integration into Android Studio.

With Android Studio 1.1 Beta you can avoid any of this plugins, or use the current master from robolectric team.

Here is a example without plugins https://github.com/nenick/AndroidStudioAndRobolectric and a guide how you do it self step by step http://nenick-android.blogspot.de/2015/02/android-studio-110-beta-4-and.html
