Unit testing with Seam

23. Apr 2008, 12:56 CET | Link Huy Nguyen Quoc

I just download the mbooking-mavenized example and added a service called LovService.After that, I created a unit test for it : LovServiceTest.

import junit.framework.Assert;

import org.jboss.seam.mock.SeamTest;
import org.jboss.seam.mock.BaseSeamTest.ComponentTest;
import org.testng.annotations.Test;

import com.gvn.platform.lov.entity.LovNode;
import com.gvn.platform.lov.service.LovService;

/**

 */
public class LovServiceTest extends SeamTest{
	
	/*
	 * Test the persistLovNode method in LovService
	 */
	@Test
	public void testPersistLovNode() throws Exception {
		new ComponentTest() {
			@Override
			protected void testComponents() throws Exception {Assert.assertNotNull(getInstance("lovService"));
				LovService lovService = (LovService) getInstance("lovService");
				LovNode newNode = lovService.newLovNode();
				newNode.setName("LOV1");
				lovService.persistLovNode(newNode);
			}
		}.run();
	}
	
	/*
	 * Test the updateLovNode method in LovService
	 */
	@Test
	public void testUpdateLovNode() throws Exception {
		new ComponentTest() {
			@Override
			protected void testComponents() throws Exception {
				LovService lovService = (LovService) getInstance("lovService");
				LovNode newNode = lovService.newLovNode();
				newNode.setName("LOV2");
				lovService.persistLovNode(newNode);
			}
		}.run();
	}
	
	/*
	 * Test the findLovNodeById method in LovService
	 */
	@Test
	public void testFindLovNodeById() throws Exception {
		new ComponentTest() {
			@Override
			protected void testComponents() throws Exception {
				Assert.assertNotNull(getInstance("lovService"));
				LovService lovService = (LovService) getInstance("lovService");
				Assert.assertNotNull(lovService.findLovNodeById(1L));
				Assert.assertEquals(1, lovService.findLovNodeById(1L).getId().longValue());
			}
		}.run();
	}
	
	/*
	 * Test the findLovNodeByName method in LovService
	 */
	@Test
	public void testFindLovNodeByName() throws Exception {
		new ComponentTest() {
			@Override
			protected void testComponents() throws Exception {
				Assert.assertNotNull(getInstance("lovService"));
				LovService lovService = (LovService) getInstance("lovService");
				Assert.assertNotNull(lovService.findLovNodeByName("LOV2"));
			}
		}.run();
	}
	
	/*
	 * Test the findLovNodeByName method in LovService
	 */
	@Test
	public void testDeleteLovNode() throws Exception {
		new ComponentTest() {
			@Override
			protected void testComponents() throws Exception {
				Assert.assertNotNull(getInstance("lovService"));
				LovService lovService = (LovService) getInstance("lovService");
				Assert.assertNotNull(lovService.findLovNodeByName("LOV2"));
				Assert.assertEquals("LOV2", lovService.findLovNodeByName("LOV2").getName());
//				lovService.deleteLovNode(lovService.findLovNodeByName("LOV2-rename"));
			}
		}.run();
	}
	
	/*
	 * Test the findAllLovNode method in LovService
	 */
	@Test
	public void testFindAllLovNodes() throws Exception {
		new ComponentTest() {
			@Override
			protected void testComponents() throws Exception {
				Assert.assertNotNull(getInstance("lovService"));
				LovService lovService = (LovService) getInstance("lovService");
				Assert.assertNotNull(lovService.findAllLovNodes());
				Assert.assertEquals(2, lovService.findAllLovNodes().size());
			}
		}.run();
	}
	
}

But there is a fail test.

Tests run: 6, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 50.076 sec <<< FAILURE!
testFindAllLovNodes(com.gvn.platform.lov.test.LovServiceTest)  Time elapsed: 0.056 sec  <<< FAILURE!
junit.framework.AssertionFailedError: expected:<2> but was:<1>

	at org.jboss.seam.mock.BaseSeamTest$ComponentTest.run(BaseSeamTest.java:169)
	at com.gvn.platform.lov.test.LovServiceTest.testFindAllLovNodes(LovServiceTest.java:139)

I didn't know how can it fail. :(. But when i checked my test database there is 2 LovNode objects.

I think all objects will be persist after the tests end. Before that only 1 object is kept. Or i made mistakes with my test class?
