Run as test suite ......

Create the other unit test files (test cases) in same package as image be shown below

You need to create all test cases in same package after that you need to create a runner class for run the all test cases as test suit. Now we think how to run the separate junit files .... :-/

we can create a runner file for run all test case .

The runner java file be shown below 

package search.test;

import org.junit.internal.TextListener;

import org.junit.runner.JUnitCore;

public class Runner {

  public static void main(String[] args) {

    JUnitCore runner = new JUnitCore();

    System.out.println("test Suite results..");

    runner.addListener(new TextListener(System.out));

    runner.run(search.class,searchFB.class);

  }

}

The image be shown below ..

After that you export the project as Runnable JAR file. Right click your project and click the export link to create below images are shown 

Make sure launch configuration and Export Destination.

After creating the jar file run the selenium RC server in command prompt and run the export jar file in another command prompt , 

command :

java -jar <test suite name>.jar

Enhancement 

Create a properties file for Server Name , Browser, Base URL and Port No.it should be easy for change the server name and other things. Properties file be shown below 

config.properties

server= localhost

browser= *firefox

Url= http://www.google.lk/

And change the each and every test cases /junit file 

public void setUp() throws Exception {

try {

            File file = new File("config.properties");

            FileInputStream fileInput = new FileInputStream(file);

            Properties properties = new Properties();

            properties.load(fileInput);

            fileInput.close();

            serv=properties.getProperty("server");

            brow=properties.getProperty("browser");

            url=properties.getProperty("Url");

            

        }

     catch (Exception e1) {

        e1.printStackTrace();

    }

selenium = new DefaultSelenium(serv, 4444, brow, url);

selenium.start();

}

Just because something doesn't do what you planned it to do doesn't mean it's useless.
