I tried to run WebDriver Sampler, but got problem with driver config.
First I tried to use Firefox Driver Config. When run only Firefox Driver Config (without any sampler) I see how Firefox launched but finally got error: org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(C:\Program Files (x86)\Mozilla Firefox\firefox.exe) on port 7055; process output follows: ddons.json found.
Next I tried to use Chrome Driver config, but got error: The driver executable does not exist.
I tried to solve the problem like this: How to solve this error an jmetere, but it doesn’t work.
