单元测试之实践四 Action的测试

 Action的测试是比较辛苦的。因为它依赖与其他的环境（比如tomcat）。
在我的印象中，基于struts的测试是很麻烦的，因为对于execute方法，你必须mock两个对象进去。
还好。基于Webwork的测试相对简单些。
下面让我们来测试一个例子吧

java 代码

1. Account account;
2. IAccountService accountService;
3. public void setAccount(Account account) {
4. this.account = account;
5. }
6. 
   
7. public void setAccountService(IAccountService accountService) {
8. this.accountService = accountService;
9. }
10. 
    
11. public String regist() throws Exception {
12. if(account == null) {
13. account = new Account();
14. return INPUT;
15. }
16. 
    
17. if(!validForm(account))
18. return INPUT;
19. 
    
20. try {
21. accountService.regist(account);
22. } catch (ObjectExistsException e) {
23. e.printStackTrace();
24. return INPUT;
25. }
26. 
    
27. return SUCCESS;
28. }
29. 
    
30. private boolean validForm(Account e) {
31. if(e.getName() == null || e.getName().trim().equals(""))
32. return false;
33. if(e.getPassword() == null || e.getPassword().trim().equals(""))
34. return false;
35. return true;
36. }

有经验的程序员见到上面的代码应该就知道怎么测试了。
我们只需setAccount，跟setAccountService即可，
而Account本身来讲就是是个po，所以可以自己new一个
AccountService则可以mock一个。真是太完美了，我太喜好mock，它总是给我惊喜

java 代码

1. package org.wuhua.action;
2. 
   
3. import junit.framework.TestCase;
4. 
   
5. import org.easymock.MockControl;
6. import org.wuhua.exception.ObjectExistsException;
7. import org.wuhua.model.Account;
8. import org.wuhua.service.IAccountService;
9. 
   
10. import sms.king.AccountManager;
11. 
    
12. import com.opensymphony.xwork.Action;
13. 
    
14. public class AccountActionTest extends TestCase {
15. private MockControl control;
16. IAccountService accountService;
17. protected void setUp() throws Exception {
18. control = MockControl.createControl(IAccountService.class);
19. accountService = (IAccountService) control.getMock();
20. 
    
21. }
22. 
    
23. public void testRegistOk() throws Exception {
24. Account employee = new Account("name");
25. employee.setPassword("password");
26. 
    
27. 
    
28. 
    
29. 
    
30. accountService.regist(employee);
31. control.setVoidCallable(1);
32. 
    
33. control.replay();
34. 
    
35. AccountAction action = new AccountAction();
36. action.setAccount(employee);
37. action.setAccountService(accountService);
38. 
    
39. assertEquals(Action.SUCCESS, action.regist());
40. 
    
41. control.verify();
42. }
43. 
    
44. public void testRegistNameExists() throws Exception {
45. Account employee = new Account("name");
46. employee.setPassword("password");
47. 
    
48. 
    
49. 
    
50. 
    
51. accountService.regist(employee);
52. control.setThrowable(new ObjectExistsException(""));
53. 
    
54. control.replay();
55. 
    
56. AccountAction action = new AccountAction();
57. action.setAccount(employee);
58. action.setAccountService(accountService);
59. 
    
60. assertEquals(Action.INPUT, action.regist());
61. 
    
62. control.verify();
63. }
64. }

ok，一个测试的例子就好了。
