在软件测试中单元测试之Action的测试

在软件测试中单元测试之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

Account account;
IAccountService accountService;
public void setAccount(Account account) {
this.account = account;
}

public void setAccountService(IAccountService accountService) {
this.accountService = accountService;
}

public String regist() throws Exception {
if(account == null) {
account = new Account();
return INPUT;
}

if(!validForm(account))
return INPUT;

try {
accountService.regist(account);
} catch (ObjectExistsException e) {
e.printStackTrace();
return INPUT;
}

return SUCCESS;
}

private boolean validForm(Account e) {
if(e.getName() == null || e.getName().trim().equals(""))
return false;
if(e.getPassword() == null || e.getPassword().trim().equals(""))
return false;
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

package org.wuhua.action;

import junit.framework.TestCase;

import org.easymock.MockControl;
import org.wuhua.exception.ObjectExistsException;
import org.wuhua.model.Account;
import org.wuhua.service.IAccountService;

import sms.king.AccountManager;

import com.opensymphony.xwork.Action;

public class AccountActionTest extends TestCase {
private MockControl control;
IAccountService accountService;
protected void setUp() throws Exception {
control = MockControl.createControl(IAccountService.class);
accountService = (IAccountService) control.getMock();

}

public void testRegistOk() throws Exception {
Account employee = new Account("name");
employee.setPassword("password");




accountService.regist(employee);
control.setVoidCallable(1);

control.replay();

AccountAction action = new AccountAction();
action.setAccount(employee);
action.setAccountService(accountService);

assertEquals(Action.SUCCESS, action.regist());

control.verify();
}

public void testRegistNameExists() throws Exception {
Account employee = new Account("name");
employee.setPassword("password");




accountService.regist(employee);
control.setThrowable(new ObjectExistsException(""));

control.replay();

AccountAction action = new AccountAction();
action.setAccount(employee);
action.setAccountService(accountService);

assertEquals(Action.INPUT, action.regist());

control.verify();
}
}

ok，一个测试的例子就好了。
