单元测试之实践4 Action的测试

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
??????

1. ??????Account?account;?? IAccountService?accountService;??
2. public?void?setAccount(Account?account)?{?? ????this.account?=?account;??
3. }?? ??
4. public?void?setAccountService(IAccountService?accountService)?{?? ????this.accountService?=?accountService;??
5. }?? ??
6. public?String?regist()?throws?Exception?{?? ????if(account?==?null)?{??
7. ????????account?=?new?Account();?? ????????return?INPUT;??
8. ????}?? ??????
9. ????if(!validForm(account))??? ????????return?INPUT;??
10. ?????? ????try?{??
11. ????????accountService.regist(account);?? ????}?catch?(ObjectExistsException?e)?{??
12. ????????e.printStackTrace();?? ????????return?INPUT;??
13. ????}?? ??????
14. ????return?SUCCESS;?? }??
15. ?? private?boolean?validForm(Account?e)?{??
16. ????if(e.getName()?==?null?||?e.getName().trim().equals(""))?? ????????return?false;??
17. ????if(e.getPassword()?==?null?||?e.getPassword().trim().equals(""))?? ????????return?false;??
18. ????return?true;?? }??

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. import?junit.framework.TestCase;?? ??
3. import?org.easymock.MockControl;?? import?org.wuhua.exception.ObjectExistsException;??
4. import?org.wuhua.model.Account;?? import?org.wuhua.service.IAccountService;??
5. ?? import?sms.king.AccountManager;??
6. ?? import?com.opensymphony.xwork.Action;??
7. ?? public?class?AccountActionTest?extends?TestCase?{??
8. ????private?MockControl?control;?? ????IAccountService?accountService;??
9. ????protected?void?setUp()?throws?Exception?{?? ????????control?=?MockControl.createControl(IAccountService.class);??
10. ????????accountService?=?(IAccountService)?control.getMock();?? ???????????
11. ????}?? ??????
12. ????public?void?testRegistOk()?throws?Exception?{?? ????????Account?employee?=?new?Account("name");??
13. ????????employee.setPassword("password");?? ??????????
14. ??????? ???????????
15. ?????????? ????????accountService.regist(employee);??
16. ????????control.setVoidCallable(1);?? ??????????
17. ????????control.replay();?? ??????????
18. ????????AccountAction?action?=?new?AccountAction();?? ????????action.setAccount(employee);??
19. ????????action.setAccountService(accountService);?? ??????????
20. ????????assertEquals(Action.SUCCESS,?action.regist());?? ??????????
21. ????????control.verify();?? ????}??
22. ?????? ????public?void?testRegistNameExists()?throws?Exception?{??
