Selenium WebDriver

Virtual users simulating Real-browser interactions can be created with the new Selenium WebDriver option. While JMeter virtual users are simulating user activity by sending http requests, WebDriver virtual users are simulating real browser interactions.

Running real-browser virtual users along with regular JMeter virtual users allows to capture real-user experience performance metrics.


In OctoPerf, Selenium scripts cannot be used to generate load during your tests, their only purpose is to have a measure of the client/browser response time. The main reason for this is that browser-based Virtual Users performances are by essence unreliable. Client performances depend heavily on the client's hardware, and there's an infinity of different hardwares. Under load, response times would not be accurate anymore, resulting in non-reproducible tests.


OctoPerf runs Selenium Webdriver 4.8.0 using Chrome headless with the folowing options: --headless --disable-infobars --disable-extensions --disable-gpu --no-sandbox --disable-dev-shm-usage --ignore-certificate-errors

Create Virtual User: WebDriver

Simply enter the URLs you want your virtual user to visit:

Create Virtual User from URLs

You need to enter valid URLs and include the protocol (I.e.

Import Selenium Script

To import an existing selenium script, follow the procedure above to create a sample virtual user. Then, replace the generated script by your own Selenium WebDriver script.

Script edition

Once the virtual user is created, the virtual user contains a WebDriver action with a sample Selenium script.

Selenium Sample Script

Scripts can be added, edited or removed. A Selenium Web Driver virtual user cannot mix WebDriver scripts with regular HTTP requests for performance reasons. More advanced examples are available on the Selenium Web Driver documentation page.
