使用 NetBeans IDE 测试 Enterprise Beans

设置示例项目

下载示例项目 TestEnterpriseBean 并在 IDE 中打开它。该 bean 有一个会话 bean (AdminBean)，拥有三个简单的业务方法：

    public String getString(String name) {
                return "response:" + name;
                }

                public int getInt(int number1, int number2) {
                return number1 * number2;
                }

                public vo.Person getVO() {
                return new vo.Person("Joe User",13);
                }

生成测试

1. 右键单击项目的 Test Libraries 节点，然后选择 Add JAR/Folder 将应用程序服务器的 lib/j2ee.jar 和 lib/appserv-rt.jar 文件添加到测试类路径。
2. 展开 Enterprise Beans 节点，然后双击 AdminSB 在 Source Editor 中打开 AdminBean.java。
3. 按下 Ctrl-Alt-J 生成测试。单击 OK 使用默认值选项运行测试。
4. 删除基础架构方法的测试：
   • testSetSessionContext
   • testEjbActivate
   • testEjbPassivate
   • testEjbRemove
   • testEjbCreate
5. 将以下字段声明添加到 AdminBeanTest：

   private beantest.AdminRemote admin;

6. 右键单击 AdminBeanTest.java，然后选择 Enterprise Resources > Call Enterprise Bean。选择 AdminSB，然后单击 OK。IDE 会输入一个 lookupAdminBean 方法。
7. 更改 lookupAdminBean 方法，使用全局 JNDI 名代替本地名：

     private beantest.AdminRemote lookupAdminBean() {
                       try {
                       javax.naming.Context c = new javax.naming.InitialContext();
                       Object remote = c.lookup("ejb/AdminBean");
                       beantest.AdminRemoteHome rv =
                       (beantest.AdminRemoteHome) javax.rmi.PortableRemoteObject.narrow(remote,
                       beantest.AdminRemoteHome.class);
                       return rv.create();
                       }

8. 将以下粗体表示的代码添加到 setUp 和 tearDown 方法中：

       protected void setUp() throws Exception {
                       admin = lookupAdminBean();
                       }
   
                       protected void tearDown() throws Exception {
                       admin.remove();
                       }

9. 实现对 enterprise bean 的业务方法进行测试的方法：

       public void testGetString() throws java.rmi.RemoteException {
                           System.out.println("testGetString");
                           assertEquals("response:Test",admin.getString("Test"));
                           }
   
                           public void testGetInt() throws java.rmi.RemoteException  {
                           System.out.println("testGetInt");
                           assertEquals(5*3,admin.getInt(5,3));
                           }
   
                           public void testGetVO() throws java.rmi.RemoteException {
                           System.out.println("testGetVO");
                           assertEquals("xxxxx", admin.getVO().getName());
                           }
                       

运行测试

1. 右键单击 TestEnterpriseBean 项目，然后选择 Deploy Project。
2. 选择 Run > Test "TestEnterpriseBean" (Alt-F6)。IDE 会运行 JUnit 测试，然后显示以下输出：

   testGetString
                       testGetInt
                       testGetVO
                       Testsuite: beantest.AdminBeanTest
                       Tests run: 3, Failures: 1, Errors: 0, Time elapsed: 1.903 sec
   
                       ------------- Standard Output ---------------
                       testGetString
                       testGetInt
                       testGetVO
                       ------------- ---------------- ---------------
                       ------------- Standard Error -----------------
                       13-Jun-2005 15:02:40 com.sun.corba.ee.spi.logging.LogWrapperBase doLog
                       INFO: "IOP00710299: (INTERNAL) Successfully created IIOP
                       listener on the specified host/port: all interfaces/4681"
                       ------------- ---------------- ---------------

                       BUILD FAILED (total time: 4 seconds)

3. 现在，我们更改测试以查找正确的人。转到 TestAdminBean.java 中的 testGetVO 方法，然后进行以下更改：

       public void testGetVO() throws java.rmi.RemoteException{
                       System.out.println("testGetVO");
                       assertEquals("Joe User", admin.getVO().getName());
                       }

4. 按 Alt-F6 再次运行测试。IDE 会显示以下输出：

   testGetString
                       testGetInt
                       testGetVO
