OEPE_009：Trouble Ticket System 项目实战开发之JPA：JUnit测试

开发运行环境：OEPE 12c（12.1.1.1.0）+ WebLogic Server 12c（12.1.1.1.0）+ Oracle Database 10g Express Edition 10.2.0.1

至此，JPA的开发工作已基本完成，下面使用JUnit进行单元测试。

1. 安装JUnit Library

2. LoginDaoTest.java 

package com.oracle.ticketsystem.dao.tests;

import static org.junit.Assert.assertNotNull;

import static org.junit.Assert.assertNull;

import org.junit.Before;

import org.junit.Test;

import com.oracle.ticketsystem.beans.Technician;

import com.oracle.ticketsystem.dao.ILoginDao;

import com.oracle.ticketsystem.dao.impl.LoginJPADao;

public class LoginDaoTest {

private ILoginDao loginDao = null;

@Before

public void setUp() throws Exception {

loginDao = new LoginJPADao();

}

@Test

public void testLogin() {

// testing valid technician

String id = "peter";

String pwd = "peter";

Technician technician = loginDao.login(id, pwd);

assertNotNull("No technician found for the ID " + id + " and password "

+ pwd, technician);

// testing in-valid technician with junk parameters

id = "junk";

pwd = "junk";

technician = loginDao.login(id, pwd);

assertNull(

"Technician found for the ID " + id + " and password " + pwd,

technician);

}

}

3. ProductDaoTest.java 

package com.oracle.ticketsystem.dao.tests;

import static org.junit.Assert.assertNotNull;

import static org.junit.Assert.assertTrue;

import java.util.List;

import org.junit.Before;

import org.junit.Test;

import com.oracle.ticketsystem.beans.Product;

import com.oracle.ticketsystem.dao.IProductDao;

import com.oracle.ticketsystem.dao.impl.ProductJPADao;

public class ProductDaoTest {

private IProductDao productDao = null;

@Before

public void setUp() throws Exception {

productDao = new ProductJPADao();

}

@Test

public void testGetAllProducts() {

List allProducts = productDao.getAllProducts();

assertTrue("No results found", allProducts.size() > 0);

}

@Test

public void testGetProduct() {

long productId = 1001;

Product product = productDao.getProduct(productId);

assertNotNull("No product found for the ID " + productId, product);

}

}

4. ProductDaoTest.java 

package com.oracle.ticketsystem.dao.tests;

import static org.junit.Assert.assertNotNull;

import static org.junit.Assert.assertTrue;

import java.util.List;

import org.junit.Before;

import org.junit.Test;

import com.oracle.ticketsystem.beans.Ticket;

import com.oracle.ticketsystem.dao.ITicketDao;

import com.oracle.ticketsystem.dao.impl.TicketJPADao;

public class TicketDaoTest {

private ITicketDao ticketDao = null;

private static long testTicketId = 0;

@Before

public void setUp() throws Exception {

ticketDao = new TicketJPADao();

}

@Test

public void testAdd() {

// adding a test ticket

Ticket ticket = ticketDao.add(1001, "Mark", "mark@gmail.com",

"TestTicket", "Ticket about the test");

assertTrue("Could not add test ticket.", (ticket.getId() > 0));

testTicketId = ticket.getId();

}

@Test

public void testGet() {

// finding a test ticket

Ticket ticket = ticketDao.get(testTicketId);

assertNotNull("Could not find test ticket.", ticket);

}

@Test

public void testUpdate() {

// finding a test ticket

Ticket ticket = ticketDao.update(testTicketId, "peter",

"Getting the test ticket", "ASSIGNED");

assertNotNull("Could not update the test ticket.",

ticket.getTechnician());

assertTrue("Could not add history to test ticket.", (ticket

.getTicketHistory().size() > 0));

}

@Test

public void testGetTicketsOwnedByTechnician() {

// finding a test ticket

List tickets = ticketDao.getTicketsOwnedByTechnician("peter");

assertTrue("Could not find tickets assigned to technician 'peter'",

(tickets.size() > 0));

}

@Test

public void testGetOpenTickets() {

// finding a test ticket

List tickets = ticketDao.getOpenTickets();

assertTrue("Could not find open tickets.", (tickets.size() > 0));

}

@Test

public void testRemove() {

// finding a test ticket

ticketDao.remove(testTicketId);

// the ticket has been removed

assertTrue(true);

}

}

4. 测试

分别右键点击三个测试类，选择Run As，选择JUnit Test。

看到绿色的颜色条，说明测试通过。

说明：测试时，Console中总是会报出警告：[EL Warning]: 2012-10-01 21:12:50.858--java.lang.ClassNotFoundException: weblogic.version。

但JUnit测试是全部通过了。
