Android: Testing

1) Test

   1.1) Create a new source folder called "Test"
   1.2) Create a subclass that either extends either "TestCase" or "AndroidTestCase"*
   1.3) All method should be named like "public void testX()" where "X" is whatever you want.
   1.4) In the manifest you need to add:
 

<instrumentation
        android:name="android.test.InstrumentationTestRunner"
        android:targetPackage="<application_package" >
    </instrumentation>

If you are going to user "AndroidTestCase" you will also have to add:

<uses-library android:name="android.test.runner" />

*AndroidTestCase is useful when you need to test something that uses the context.

   1.5) Create a class that extends TestSuite as follows:

import android.test.suitebuilder.TestSuiteBuilder;
import junit.framework.Test;
import junit.framework.TestSuite;

public class AllTests extends TestSuite {
    public static Test suite() {
        return new TestSuiteBuilder(AllTests.class).includeAllPackagesUnderHere().build();
    }
}
