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

      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。
