I have Ux Automation test project where in I am using the NuGet for Selenium.Chrome.WebDriver. The Agent in the release pipeline has below versions of chrome & WebDriver

Google Chrome
version:
75.0.3770.100

Selenium Web Drivers
Chrome Driver
version:
75.0.3770.90
Environment:
ChromeWebDriver: location of chromedriver.exe

I have tried check-in the project with 75 & 76 NuGet reference. However, I am getting below error in both cases.

System.InvalidOperationException: session not created: This version of ChromeDriver only supports Chrome version 76 (SessionNotCreated)

Which version it is complaining for?

This error message...

System.InvalidOperationException: session not created: This version of ChromeDriver only supports Chrome version 76 (SessionNotCreated)

...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser session.

Your main issue is the incompatibility between the version of the binaries you are using as follows:

  • Though you mentioned about using chromedriver=75.0.3770.90 there may be multiple instances of chromedriver being present in your system and the the version of the chromedriver which is effective in your tests is chromedriver=76.0
  • Release Notes of chromedriver=76.0 clearly mentions the following :

Supports Chrome version 76

  • Presumably you are using chrome= 75.0.
  • Release Notes of ChromeDriver v75.0 clearly mentions the following :

Supports Chrome 75

So there is a clear mismatch between the ChromeDriver v76.0 and the Chrome Browser v75.0

Solution

Ensure that:

  • Selenium is upgraded to current levels Version 3.141.59.
  • ChromeDriver is updated to current ChromeDriver v79.0.3945.36 level.
  • Chrome is updated to current Chrome Version 79.0 level. (as per ChromeDriver v79.0 release notes)
  • Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
  • If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
  • Take a System Reboot.
  • Execute your @Test as non-root user.
  • Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
