First you must have TestOptimal installed in your IDE by following Installation.

To execute MBT model or execute a specific test case (mCase), create the test java class inheriting from test case as you normally do to create JUnit class. Add a static initializer as the following to start up TestOptimal server and to open the MBT model.

Now you are ready to write your test case to execute MBT model or a specific test case (mCase) in the model. See example below.

Make sure you do not have any instance of TestOptimal running as JUnit class will try to start TestOptimal server as part of the startup process.

 import junit.framework.TestCase;
 import com.webmbt.TestOptimalClient;
 public class JUnitWebStore extends TestCase {
   /**
    * Example to run a specific mCase.  It is assumed that sequencer/mode has been set to mCaseSequencer and
    * appropriate plugin/browser settings have been set appropriately.
    * @throws Exception
    */
    public void testRemoveItemScenario() throws Exception {
       TestOptimalClient.executeModel("RemoveItemScenario", "Junit testing RemoveItemScenario");
    }
   /**
    * Example to run the model.  It is assumed that sequencer/mode has been set to mCaseSequencer and
    * appropriate plugin/browser settings have been set appropriately.
    * @throws Exception
    */
    public void testQuickPurchaseScenario() throws Exception {
       TestOptimalClient.executeModel(null, "Junit testing complete model");
    }
   /**
    * starts up **//TestOptimal//** server and opens the mbt model.
    */
    static {
   	try {
	   TestOptimalClient.startTestOptimalServer(new String[]{});
           TestOptimalClient.openModel("WebStore.scxml");
        }
	catch (Exception e) {
	   e.printStackTrace();
	}
    }
  }
