I think it could be useful to run System Test with multiple browsers when using Selenium, in order to get better testing coverage for different browsers.
For instance if you could put an array of browsers inside the using variable:
class ApplicationSystemTestCase < ActionDispatch::SystemTestCase
driven_by :selenium, using: [:chrome, :firefox], screen_size: [1000, 1000]
I know its possible to run capybara with multiple browser using RSpec, like this: https://stackoverflow.com/questions/39955782/capybara-rspec-how-to-set-up-multi-browser-tc-running
What are your thoughts?
