Putting UIAutomator tests together to a test suite is a quick thing:
package de.androidtest.myapplication;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
@RunWith(Suite.class)
@Suite.SuiteClasses({InterAppTest1.class, InterAppTest2.class})
public class AppTestSuite {}
Execute similar to a single test by clicking right and run the suite.
