Tips on extracting variables from JMeter Selenium WebDriver

Currently, I am dealing with a token that is being returned in the body of a web page.

WDS.browser.findElement(org.openqa.selenium.By.xpath("//*[contains(@name,'RequestVerificationToken')]")).getText();

This token is what I need to extract:

My goal is to pass this variable out of the selenium webdriver and share it across all threads.

Typically, when working with regular pages, I use a regular expression extractor as a post processor to set it to a variable for correlation. However, in this scenario, I am uncertain about the approach.

How can I transform this into a global variable in JS?

Answer №1

If you take into account the entire value of the name attribute, you will notice that the token actually represents the value attribute. This means that in order to retrieve it, you should utilize getAttribute("value") instead, like so:

WDS.browser.findElement(org.openqa.selenium.By.xpath("//input[@name='__RequestVerificationToken']")).getAttribute("value");

The element you wish to interact with does not contain text. You need to utilize the value attribute. Update your code as follows:

var token = WDS.browser.findElement(org.openqa.selenium.By.xpath("//*[contains(@name,'RequestVerificationToken')]")).getAttribute('value')

If you want to share this token across multiple threads within the same or different Thread Groups, store it in a JMeter Property like so:

WDS.props.put('token', token)

This will allow you to access the token in other WebDriver Sampler instances using:

var token = WDS.props.get('token')

In other JMeter test elements, you can use the __P() function like this:

${__P(token,)}
