Struts2 Action的单元测试

　　对Struts2进行单元测试，以struts 2.2.1.1为例 ，可以使用struts2发行包中的struts2-junit-plugin-2.2.1.1.jar，它里面提供了两个类StrutsTestCase、StrutsSpringTestCase，分别提供对纯struts应用和struts+spring整合时的单元测试支持。下面分别说明。

　　1.StrutsTestCase

　　首先准备一个纯struts2工程，建立工程过程略，但有如下的类：

　　Account.java，是bean

package model;

public class Account {
    private String userName;
    private String password;

    public Account() {
    }

    public Account(String userName， String password) {
        this.userName = userName;
        this.password = password;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

　　AccountAction.java

package action;

import com.opensymphony.xwork2.ActionSupport;
import model.Account;

import java.util.logging.Logger;

public class AccountAction extends ActionSupport{

    private Account accountBean;
    public String execute() throws Exception {
        return SUCCESS;
    }

    public void validate(){
        if (accountBean.getUserName().length()==0){
            addFieldError("accountBean.userName"，"User name is required.");
        }

        if (accountBean.getUserName().length()<5){
            addFieldError("accountBean.userName"，"User name must be at least 5 characters long.");
        }

        if (accountBean.getUserName().length()>10){
            addFieldError("accountBean.userName"，"User name cannot be at more thant 10 characters long.");
        }
    }

    public Account getAccountBean() {
        return accountBean;
    }

    public void setAccountBean(Account accountBean) {
        this.accountBean = accountBean;
    }
}
