My issue: chromedriver and chrome versions do not match in my test runs
I use a custom docker image for my test runs (RHEL Linux). In this I install the latest version of Google Chrome rpm, and another older version of Chrome for testing. The main reason I am doing this is the Google Chrome RPM handles all the dependencies for me since the Chrome for testing only comes as a zip, but I also want to have a specific slightly older version for certain purposes (which Google chrome rpm package does not provide, it's always latest).
Google Chrome (RPM) installs in
/usr/bin/google-chrome
/usr/bin/google-chrome -> /etc/alternatives/google-chrome
/etc/alternatives/google-chrome -> /usr/bin/google-chrome-stable
E.g. when I execute "google-chrome --version" in the docker image I get
122.0.6261.57
Chrome for testing (ZIP) gets installed in
/usr/local/opt/chrome-linux64
with:
/usr/local/bin/chrome -> /usr/local/opt/chrome-linux64/chrome
120.0.6099.109
Furthermore, I install chromedriver for both versions in my
~/.cache/selenium/chromedriver/
so this has two subfolders with the respective versions mentioned above. And also /usr/local/bin/chromedriver is linked to the latest version (122)
Now when I run selenium with webdrivermanager, trying to use "just google-chrome" I get the following result:

So webdrivermanager finds the right browser (google-chrome v122) and the matching chromedriver.
But then my tests fail with an error:
1) Error in custom provider, org.openqa.selenium.SessionNotCreatedException: session not created: This version of ChromeDriver only supports Chrome version 122
Current browser version is 120.0.6099.109 with binary path /usr/local/bin/chrome
But according to https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver/01fde32d0ed245141e24151f83b7c2db31d596a4 the default search path should be
/usr/bin/google-chrome
so why does it pick /usr/local/bin/chrome ?
Note: in my code I am just calling
WebDriverManager.chromedriver().setup();
I am not setting any binary path options in this case.
If the chromedriver instance was set up with the latest version (122), should it not also start that browser when being used?
So I finally found an approach that works:
WebDriverManager.chromedriver().setup(); in the code as normalWebDriverManager.chromedriver().browserVersionDetectionCommand(customChromePath+ " --version").setup(); chromeOptions.setBinary(customChromePath);then the selection of both browser and matching chromedriver will work as expected with webdrivermanager (5.7.0 at least)
