I've got headless Chrome and Chrome working for my Rspec tests. I want a flag to switch between the two so I can see the tests happen when I want and hide them when I don't. How can I implement something like:
rspec --headless Right now I just have this secret tied to a .env var:
Capybara.javascript_driver = Rails.application.secrets.headless ? :headless_chrome : :chrome in your rails_helper.rb you should create a statement like that:
RSpec.configure do |config| config.before(:each) do if ENV['HEADLESS'] == 'true' Capybara.current_driver = :selenium_chrome_headless else Capybara.current_driver = :selenium_chrome end end end then send a variable when running specs
$ HEADLESS=true rspec ./spec/features Well, overriding the env var works so that's something.
HEADLESS=true rspec 
Hmm, I personally use this code to register driver:
Capybara.register_driver :chrome do |app| capabilities = Selenium::WebDriver::Remote::Capabilities.chrome( chromeOptions: { args: [ ('headless' if ENV.fetch('HEADLESS', '1') == '1') ].compact } ) Capybara::Selenium::Driver.new( app, browser: :chrome, desired_capabilities: capabilities ) end then in .env you can set the variable to be HEADLESS or not by default and then if you want to overwrite it just type HEADLESS=0 rspec
