SSH架构开发流程3

Hibernate第三步：

开发测试用例AddressDAOTest.java测试AddressDAO.java

 

通常开发完DAO层的代码 都需要辨析JUnit测试用例来进行数据层测试 下面我们就来编写一个测试用例类来测试AddressDAO.java 包括

[1]编写单元测试类AddressDAOTest.java

[2]编写测试套件类AllTest.java

 

 

[1]编写单元测试类AddressDAOTest.java

通常测试用例类都以“*Test”形式命名 该类必须继承TestCase 并包含一个addressDAO对象 该对象在setUp()中通过FileSystemXmlApplicationContext类来读取Bean的配置文件 然后使用getBean()取得。

package com.demo.hibernate.test;

import java.util.Iterator;
import java.util.List;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

import com.demo.hibernate.beans.Address;
import com.demo.hibernate.dao.IAddressDAO;
import com.demo.hibernate.dao.AddressDAO;

import junit.framework.TestCase;

public class AddressDAOTest extends TestCase {

    public IAddressDAO addressDAO;

    public AddressDAOTest(String name) {
        super(name);
    }

    protected void setUp() throws Exception {
        super.setUp();
        addressDAO = new AddressDAO();
        ApplicationContext ctx = new FileSystemXmlApplicationContext(
                "WebRoot/WEB-INF/applicationContext.xml");
        addressDAO = (IAddressDAO) ctx.getBean("addressDAO");
    }

    protected void tearDown() throws Exception {
        super.tearDown();
    }

    public void testFindAllByUsername() throws Exception {
        List list = addressDAO.findAllByUsername("admin");
        assertTrue(list.size() == 0);
        Iterator it = list.iterator();
        while (it.hasNext()) {
            Address address = (Address) it.next();
            assertNotNull(address);
        }
    }

    public void testFindById() throws Exception {
        Address address = addressDAO.findById("1");
        assertNotNull(address);
    }

    public void testI***ist() throws Exception {
        boolean b = addressDAO.i***ist("admin", "lzb");
        assertTrue(b);
    }

    public void testInsert() throws Exception {
        Address address = new Address();
        address.setUsername("admin");
        address.setName("andy");
        address.set***("2");
        address.setMobile("13888886666");
        address.setEmail("[e-mail]");
        address.setQq("12345678");
        address.setCompany("Intel");
        address.setAddress("上海市");
        address.setPostcode("200089");
        addressDAO.insert(address);

        address = addressDAO.findById("2");
        assertNotNull(address);
    }

    public void testUpdate() throws Exception {
        Address address = new Address();
        address.setId(new Integer(2));
        address.setUsername("admin");
        address.setName("andy");
        address.set***("2");
        address.setMobile("13888886666");
        address.setEmail("[e-mail]");
        address.setQq("12345678");
        address.setCompany("Microsoft");
        address.setAddress("上海市");
        address.setPostcode("200089");
        addressDAO.update(address);

        Address address2 = addressDAO.findById("2");
        assertTrue(address2.getCompany().equals("Microsoft"));
    }

    public void testDelete() throws Exception {
        addressDAO.delete("2");

        Address address = addressDAO.findById("2");
        assertNull(address);
    }

}

 

[2]编写测试套件类AllTest.java

编写一个测试套件类AllTest.java 用来启动addressDAOTest.java的测试代码 该类必须继承TestCase 并编写一个测试入口函数suite() 在该函数中创建一个TestSuite类型的变量 并使用addTest()函数增加addressDAOTest.class的测试类 然后返回该套件变量suite。

然后编写一个主函数main() 使用TestRunner来运行suite()函数

package com.demo.hibernate.test;

import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;

public class AllTest extends TestCase {

    public static void main(String[] args) {
        junit.textui.TestRunner.run(suite());
    }

    public static Test suite() {
        TestSuite suite = new TestSuite("Test for test");

        suite.addTest(new TestSuite(AddressDAOTest.class));
        return suite;
    }
}

用鼠标右键单击测试套件类AllTest.java 在弹出的快捷菜单中选择运行-JUnit命令 即开始测试以上六个函数。

如果现实的绿色的进度条 说明6个任务都测试成功了 这样就可以放心食用AddressDAO.java中的函数了
