如何从 WebDriver Sampler 中设置 JMeter Vars? [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.

我可以成功地使用 CSS/JQuery Extractor 向 JMeter 变量添加值...

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

但是如何在 WebDriver Sampler 中执行相同的操作?

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，它的实现方式为 JSR 223 标准 例如你可以参考 JMeter 变量(又名 vars 如下)

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
