I’m trying to setup JUnit to test my activities for an android project.

The Android Project runs ok on both an AVD and a device (there are still a few bugs left, which is why I want to add a few unit tests)

I followed the steps from these websites (they are more or less the same, but I still checked all of them just to make sure I did everything correctly)
http://mobile.tutsplus.com/tutorials/android/android-sdk-junit-testing/
http://developer.android.com/tools/testing/testing_eclipse.html

I created a test project using the same workspace as my project, and created my first test case. When I tried to run the test, I got the following:

[2012-12-09 19:42:56 – AssassinTest] Android Launch!
[2012-12-09 19:42:56 – AssassinTest] adb is running normally.

[2012-12-09 19:43:04 – AssassinTest] Test run failed: Instrumentation run failed due to ‘java.lang.ClassNotFoundException’

And here is what I get from LogCat:

While searching on a few forums, I read that this might be caused by a bad manifest file, but I don’t see what is wrong with mine

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="udes.assassin.test"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="10" />

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

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <uses-library android:name="android.test.runner" />
</application>
</manifest>

And finally, this is the code in my only JUnit class (so far)

package udes.assassin.test;
import static org.junit.Assert.*;
import org.junit.Before;
import org.junit.Test;
import udes.assassin.InGameActivity;
import android.test.ActivityInstrumentationTestCase2;

public class InGameActivityTest 
        extends ActivityInstrumentationTestCase2<InGameActivity> {

    public InGameActivityTest() {
        super("udes.assassin", InGameActivity.class);
    }

    public InGameActivityTest(Class<InGameActivity> activityClass) {
        super(activityClass);
    }

    @Before
    protected void setUp() throws Exception {
        super.setUp();
    }

    @Test
    public void testSetItemPosition() {
        fail("Not yet implemented");
    }
}

Thank you

    It is probably because JUnit is not in your classpath. Go to Project -> Properties -> Java Build Path -> Order and Export and check if the JUnit box is unchecked.
