I am using Android Studio 0.2.4, but I assume this question can pertain to IntelliJ in general. My tests are under src/instrumentTest/java and all extend AndroidTestCase. When I run all the tests (say by right clicking on the source folder and clicking "Run...") the tests run just fine on the Android emulator as Android Tests (as seen under the Run/Debug Configurations).
But if I try to run a single test method or test class the same way (right click on the method and click "Run..."), the test runs as a normal JUnit test not on the emulator, which of course fails (stack trace below). Even if I try to create a new Run Configuration, I see no way a creating anything other than a JUnit configuration.
From the IDE, how do run a test method or test class as an Android Test?

To run all the tests in a default group, choose the Run icon and then choose the group on the menu. Select the individual tests that you want to run, open the right-click menu for a selected test and then choose Run Selected Tests (or press Ctrl + R, T).
Create Test Runner Class It imports the JUnitCore class and uses the runClasses() method that takes the test class name as its parameter. Compile the Test case and Test Runner classes using javac. Now run the Test Runner, which will run the test case defined in the provided Test Case class. Verify the output.
To get started, select a method, a type, or a namespace in the code editor in the project you want to test, right-click, and then choose Create Unit Tests. The Create Unit Tests dialog opens where you can configure how you want the tests to be created.
For anyone still following, this works in Android Studio 0.2.8. There are three states you need to be aware of though.
If you've never run the test method or class before, there will be no saved run configuration. So right click on the method or class and there should be a right arrow next to Run which displays the name of your test. Choose the one that has the Android symbol.
If you've run the test method or class as a regular JUnit test before, then Android Studio will have saved that configuration and there will be no right arrow or options under Run in the context menu. In that case, in the file menu go to Run->Edit Configurations..., find your test under the JUnit section, and delete it. Then you should be in state (1).
If you've run the test method or class as an Android test before, then Android Studio will have saved that configuration and there will be no right arrow or options under Run in the context menu. Just selecting Run should work.

Did you set up your test code correctly in Android Studio? Gradle's latest convention in Android Studio is to call your tests directory 'androidTest'. Then in your build.gradle file you need to put:
androidTest.setRoot('androidTest') androidTest.java.srcDirs = ['androidTest/java'] Then you can right-click on any test class individually and run it.
EDIT: These instructions are for espresso tests only.
