如何在WebDriver Sampler中设置JMeter变量？ [英] How to set JMeter Vars from within WebDriver Sampler?

问题描述

// I had previously used a CSS/JQuery extractor to get a URL from a page and add it to JMeter vars - accessing it here
var pageURL = "${valueFromJmeterVars}";

// navigate to that url
WDS.browser.get(pageURL); 

// selecting an element
var button = wait.until(pkg.ExpectedConditions.visibilityOfElementLocated(pkg.By.cssSelector(buttonLocator)));                                                                                                                                               

// log desired boolean value to console, so I can confirm is as expected
WDS.log.info('reserveASpotButton:' + reserveASpotButton.isEnabled());

// add my boolean to JMeter vars, so I can access later from beanshell post-processor (where I do my assertions)
vars.put("reserveASpotButtonIsEnabled", reserveASpotButton.isEnabled());

上面的最后一行不起作用。

The last line above doesn't work.

我可以成功使用CSS / JQuery Extractor为JMeter vars添加值...

I can successfully use CSS/JQuery Extractor to add values to JMeter vars...

但怎么能我是从WebDriver Sampler中做同样的事情吗？

But how can I do the same from within WebDriver Sampler?

推荐答案

您可以从WebDriver Sampler中访问JMeter API类，它实现为< a href =https://jcp.org/en/jsr/detail?id=223 =nofollow> JSR 223标准，例如你可以参考JMeter变量（又名 vars 如下所示）

You can access JMeter API classes from within the WebDriver Sampler, it's implemented as JSR 223 standard for instance you can refer JMeter Variables (aka vars as follows)

在WebDriver采样器中：

In the WebDriver Sampler:

var ctx = org.apache.jmeter.threads.JMeterContextService.getContext()
var vars = ctx.getVariables();

vars.put('foo','bar')

现在你有 $ {foo} 变量，其值为 bar

Now you have ${foo} variable with the value of bar
