如何对修改密码接口进行压测？终于找到解决办法了

做接口测试中，对于一般性的单业务接口测试很多工具可供选择，但是对于一些相关业务相关性的关联接口测试就比较麻烦，使用工具比如jmeter、postman、soapui等等就比较麻烦。我比较偏重脚本化执行测试用例，所以选择了groovy作为主要语言来进行接口测试，但是脚本依赖的库还是基于之前所在的java为主的测试框架，有兴趣的可以翻翻以前的文章。项目的架构思路是以模块为基础把接口分类，然后对于接口的请求单独进行实现。通过一个user作为一个用户，携带各种属性，如：uname，pwd，token，userinfobean等信息。来作为各个模块类之间的信息传递。

回到修改密码接口，简单说一下我们接口的逻辑，先登录，获取token作为用户身份的唯一校验值，修改密码接口参数，newpwd，oldpwd，token。成功之后会返回新的token，作为用户继续其他操作的校验值。

分享一下测试脚本代码：

class T8 extends OkayBase {public static void main(String[] args) {int thread =changeStringToInt(args[0])int times =changeStringToInt(args[1])List<ThreadBase> threads = new ArrayList<>()for (int i = 0; i < thread; i++) {OkayBase base = getBase(i)UserCenter userCenter = new UserCenter(base)userCenter.modifyPwd()ThreadBase threadBase = new ThreadBase() {@Overrideprotected void before() {}@Overrideprotected void doing() throws Exception {userCenter.modifyPwd()}@Overrideprotected void after() {}}threadBase.setTimes(times)threads.add(threadBase)}new Concurrent(threads).start()allOver()}
}

main方法留了两个参数表示线程数和单线程请求数，下面是usercenter的主要代码。

public class UserCenter extends OkayBase {private static Logger logger = LoggerFactory.getLogger(UserCenter.class);public UserCenter(OkayBase okayBase) {super(okayBase);}public JSONObject modifyPwd() {String url = UserApi.MODIFY_PWD;JSONObject params = getParams();params.put("newpwd", getPassword(this.getUname()));params.put("oldpwd", getPassword(this.getPwd()));JSONObject response = getPostResponse(url, params);output(response);if (isRight(response)) {String string = response.getJSONObject("data").getString("token");this.setToken(string);}return response;}
}

下面是okaybase的主要代码：

public class OkayBase extends SourceCode implements IBase {private static Logger logger = LoggerFactory.getLogger(OkayBase.class);int uid;String token;String uname;String pwd;public OkayBase(String uname, String pwd) {this.uname = uname;this.pwd = pwd;login();}public String getPassword() {String s = uname.substring(uname.length() - 6);return getPassword(s);}public String getPassword(String pwd) {return RSAUtils.getPassword(pwd);}public JSONObject getParams() {JSONObject json = getJson("uid=" + uid, "token=" + token);json.put("imei", "isFake");json.put("serial", "W170500652");json.put("ua", "f_an_4..0");return json;}public String getPwd() {return pwd;}public void setPwd(String pwd) {this.pwd = pwd;}public int getUid() {return uid;}public String getToken() {return token;}public void setToken(String token) {this.token = token;}public String getUname() {return uname;}@Overridepublic boolean isRight(JSONObject jsonObject) {int code = TEST_ERROR_CODE;try {code = jsonObject.getJSONObject("meta").getInt("ecode");JSONObject data = jsonObject.getJSONObject("data");return code == 0 && !data.isEmpty();} catch (Exception e) {return false;}}/*** 测试结束，资源释放*/public static void allOver() {FanLibrary.testOver();}
}
