    }
}

And when I tried to call the AppTest using main method of another class, it's giving me error as : java.lang.ClassNotFoundException: user.login.creation.UserValidation.AppTest

public class App 
{
    public static void main( String[] args )
    {
        System.out.println( "setup!" );
        AppTest app = new AppTest();
        app.run();
    }
}

Error

Exception in thread "main" java.lang.NoClassDefFoundError: user/login/creation/UserValidation/AppTest
    at user.login.creation.UserValidation.App.main(App.java:12)

I want to run that test cases from the main method, any suggestions ?
