Jmeter系列-webdriver代码范例

范例

WDS.sampleResult.sampleStart()
try{
//打开博客首页
WDS.browser.get('http://xqtesting.blog.51cto.com')
//测试代码结束
WDS.sampleResult.sampleEnd()
}catch(x){
WDS.sampleResult.sampleEnd()
//设置为结果失败
WDS.sampleResult.setSuccessful(false)
//返回信息设置为-_- sorry
WDS.sampleResult.setResponseMessage('-_- sorry')
}

以上是最简单的使用，算是一个尝鲜吧，其中WebDriver Sampler中代码编写可以扩展，和你编写WebDriver一样，可以利用By.id，By.cssSelector等方法进行元素的定位并操作，类似如下代码：

var pkg = JavaImporter(org.openqa.selenium)
WDS.browser.findElement(pkg.By.id('what')).sendKeys(['xiaoqiang'])

 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()
 }

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。
