Normally, you can't. Welcome to the world of Android, where all tests must run on a device(except Robolectric).

The main reason is that you don't actually have the framework's sources - even if you convince the IDE to run the test locally, you will immediately get a "Stub! Not implemented" exception.
"Why?" you might wonder? Because the <code>android.jar</code> that the SDK gives you is actually all stubbed out - all the classes and methods are there but they all just throw an exception. It's there to provide an API but not there to give you any actual implementation.

There's a wonderful project called <a href="http://robolectric.org/">Robolectric</a> which implements a lot of the framework just so you can run meaningful tests. Coupled with a good mock framework (e.g., Mockito), it makes your job manageable.

By the way, you should note that the scope of the dependencies for simple JUnit test should be "testCompile".

I am using <code>Android Studio/IntelliJ</code> to build on an existing <code>Android</code> project and would like to add some simple <code>JUnit</code> unit tests. What is the right folder to add such tests on?

The android <code>Gradle</code> plug-in defines a directory structure with <code>src/main/java</code> for the main source code and <code>src/instrumentTest/java</code> for <code>Android</code> tests. 

Trying to add my JUnit tests in instrumentTest didn't work for me. I can run it as an <code>Android</code> test (that's what that directory seems for) but that's not what I'm looking for - I just want to run a simple <code>JUnit</code> test.
I tried creating a JUnit run configuration for this Class but that also didn't work - I'm supposing because I'm using a directory that is flagged as <code>Android</code> Test instead of Source.

If I create a new source folder and marki it as such in Project Structure, this will get wiped next time <code>IntelliJ</code> refreshes the project configuration from the gradle build files.

What is the more appropriate way of configuring JUnit tests in an gradle-based android project on <code>IntelliJ</code>? Which directory structure to use for this?
