Selenium may break with ChromeDriver 75+

This fix is not recommended anymore since Chrome 91 will raise further issues. It looks like recent Selenium versions don't have any issues with the w3c interface anymore.

When you update your ChromeDriver to version 75 or beyond, you might get w3c errors in your tests.

For example, reading the browser console for errors no longer works, and page.driver.browser.manage.logs.get(:browser) will raise an error like "undefined method `log' for #<Selenium::WebDriver::Remote::W3C::Bridge:0x000055903f307aa8>".

Add options.add_option('w3c', false) to your Selenium configuration (e.g. features/support/selenium.rb) and you should be back to normal:

Copy
Capybara.register_driver :selenium do |app| options = Selenium::WebDriver::Chrome::Options.new(args: %w[--disable-infobars]) options.add_option('w3c', false) Capybara::Selenium::Driver.new(app, browser: :chrome, options: options) end

By refactoring problematic code and creating automated tests, makandra can vastly improve the maintainability of your Rails application.
