JMeter (2) —— JMeter与WebDriver测试用户登陆以CAS SSO为例（101 Tutorial）

新建测试计划（TestPlan）
为测试计划添加线程组（TheadGroup）
依次添加
- jp@gc - Firefox Driver Config (Thread Group -> Config Element)
- jp@gc - WebDriver Sampler (Thread Group -> Sampler)
- View Results Tree (Thread Group -> Listender)
- View Results in Table (Thread Group -> Listender)

测试本地的CAS单点登陆环境

脚本

 try {
     
     var pkg = JavaImporter(org.openqa.selenium, org.openqa.selenium.support.ui)
     WDS.log.info('WDS Name:' + WDS.name)
     WDS.sampleResult.sampleStart()
     
     WDS.browser.navigate().to('https://app2.hoau.com:8423/cas2')
     WDS.log.info('Browser Title:' + WDS.browser.getTitle())
     WDS.log.info('Browser CurrentUrl:' + WDS.browser.getCurrentUrl())    
     WDS.log.info('Cookie:' + WDS.browser.manage().getCookies())   
     WDS.log.info('Request Header: ' + WDS.sampleResult.getRequestHeaders())
     
     var what = WDS.browser.findElement(pkg.By.id('username'))
     what.sendKeys(['test01'])
     var where = WDS.browser.findElement(pkg.By.id('password'))
     where.sendKeys(['psw01'])
     
  
     //   var button = WDS.browser.findElement(pkg.By.cssSelector('.btn-submit'))
     var button = WDS.browser.findElement(pkg.By.xpath("//input[@type='submit']"))
     button.click()
     
     
     var wait = new pkg.WebDriverWait(WDS.browser, 10)
     wait.until(pkg.ExpectedConditions.presenceOfElementLocated(pkg.By.xpath("//a[@title='Click here to log out']")))
     var results = WDS.browser.findElements(pkg.By.xpath("//a[@title='Click here to log out']"))
     WDS.log.info('Result: ' + results)
     
     if(results.empty) {
         WDS.sampleResult.successful = false
         WDS.sampleResult.responseMessage = 'There were no results returned'
     }
     
     var iter = results.iterator()
     var element = iter.next()
     WDS.log.info('User: ' + element.getText())
     
     if('test01' != element.getText()) {
         WDS.sampleResult.successful = false
         WDS.sampleResult.responseMessage = 'Login Failure'
     }
     
     WDS.sampleResult.sampleEnd()
 } catch(ex) {
     WDS.log.error(ex)
     WDS.sampleResult.successful = false
     WDS.sampleResult.responseMessage = 'There were no results returned'
     WDS.sampleResult.sampleEnd()
 }

运行
- 查看“View Results in Table”
- 查看“View Results Tree”

需要注意的是，诸如JMeter + WebDriver Plugin或Selenium Grid + Remote WebDriver抑或Sahi Web UI这些方式的测试，都是试图模拟用户从终端（浏览器）与服务器进行真实交互，以上这些方式长于流程、场景，而非服务端的压力（当然也可用于服务端压力测试之目的，这里强调的只是意图），如果要对服务端进行压力测试，我们可以有其他更为适合的方式。

测试cnblogs登陆

我们同样可以cnblogs为目标系统，尝试用JMeter来测试cnblogs的登陆。

脚本

 try {
     
     var pkg = JavaImporter(org.openqa.selenium, org.openqa.selenium.support.ui)
     WDS.log.info('WDS Name:' + WDS.name)
     WDS.sampleResult.sampleStart()
     
     WDS.browser.navigate().to('http://passport.cnblogs.com/user/signin')
     WDS.log.info('Browser Title:' + WDS.browser.getTitle())
     WDS.log.info('Browser CurrentUrl:' + WDS.browser.getCurrentUrl())    
     WDS.log.info('Cookie:' + WDS.browser.manage().getCookies())   
     WDS.log.info('Request Header: ' + WDS.sampleResult.getRequestHeaders())
     
     var what = WDS.browser.findElement(pkg.By.id('input1'))
     what.sendKeys(['weizhe_2008'])
     var where = WDS.browser.findElement(pkg.By.id('input2'))
     where.sendKeys(['********'])
     var button = WDS.browser.findElement(pkg.By.id('signin'))
     button.click()
     
     var wait = new pkg.WebDriverWait(WDS.browser, 1)
     // a href="http://home.cnblogs.com/u/richaaaard/"
     wait.until(pkg.ExpectedConditions.presenceOfElementLocated(pkg.By.xpath("//a[@href='http://www.cnblogs.com/richaaaard/']")))
     var results = WDS.browser.findElements(pkg.By.xpath("//a[@href='http://www.cnblogs.com/richaaaard/']"))
     WDS.log.info('Result: ' + results)
     
     if(results.empty) {
         WDS.sampleResult.successful = false
         WDS.sampleResult.responseMessage = 'There were no results returned'
     }
     
     WDS.sampleResult.sampleEnd()
 } catch(ex) {
     WDS.log.error(ex)
     WDS.sampleResult.successful = false
     WDS.sampleResult.responseMessage = 'There were no results returned'
     WDS.sampleResult.sampleEnd()
 }

运行
结果

问题

由于此种测试模式下，我们会使用JMeter配置的Firefox Driver Config组件，同时使用WDS（Web Driver Sampler）Script在JMeter UI环境下测试目标应用，当Thread Group 的循环次数（Loop Count）或线程数（Number of Threads (user)）的值大于1时，当前线程关联的浏览器代理实例一直处于生命期，而单点登陆会保留用户的登陆信息，无需反复输入用户名密码，浏览器保持了这些信息，因此后面断言会出现错误，脚本无法反复执行从而达到为“验证用户名密码这个流程”进行压力测试的目的。

经研究，当前版本的JMeter及其使用的Selenium WebDriver Plugin除PhantomJS外，不支持动态修改Session Cookie，而网上多数文章介绍的相关Cookie的API，无法对浏览器Session Cookie进行操作。
```
  WDS.browser.manage().getCookies()
  WDS.browser.manage().deleteAllCookies()
```
我们会使用HTTPs录制的方式来解决压力测试的问题。

扩展

为了解WDS 在JMeterUI下javascript脚本的能力，以及涉及到面问题相关的源码。
