Using Selenium with JMeter's WebDriver Sampler
请参照JMeter (1) —— JMeter与WebDriver安装与测试(101 Tutorial) 安装好JMeter。
需要注意的是:
请参照以下文章搭建配置好CAS单点登陆的本地环境。
CAS (1) —— Mac下配置CAS到Tomcat(服务端)
CAS (2) —— Mac下配置CAS到Tomcat(客户端)
CAS (6) —— Nginx代理模式下浏览器访问CAS服务器网络顺序图详解
CAS (7) —— Mac下配置CAS 4.x集群及JPATicketRegistry(服务端)
注意:我们这里只是以CAS单点登陆为应用场景进行测试,此测试可以推广到其他的web应用的登陆场景,也可以扩展到更为丰富的流程或场景中。
新建测试计划(TestPlan)
为测试计划添加线程组(TheadGroup)
依次添加
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
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
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。
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。
