I'm using WSL for Rails system tests on 5.1 with rspec/capybara/selenium and ran into a similar issue.
Instead of /usr/bin/chromium-browser, my process initiating chrome was at /usr/local/bin/google-chrome. I was able to resolve the error by creating a symlink to chrome.exe on my Windows file system (in the Program Files (x86) folder). From a bash shell: *cd /usr/local/bin* *ln -s "/mnt/c/Program Files (x86)/Google/Chrome/Application/chrome.exe" /usr/local/bin (*create a symlink to Chrome on Windows file system. Your Chrome path may be different) *mv chrome.exe chrome* (rename 'chrome.exe' as 'chrome' for selenium driver used in system tests) Hope this helps.
