Rspec+Capybara optionally change JS driver

I use poltergeist/phantomjs for CI, but I want to be able to optionally change the JS driver to selenium to watch my test runs locally. Ideally I'd like to have a command line flag for this- default poltergeist, but be able to run rspec --driver=selenium (or something similar)

Any ideas?

Solution

  • Never ended up finding an answer for this, so here's the hacky solution I came up with:

    The only thing I found that I could reliably change was the tagging system. So I call using -t visual tag and then take it away.

    In spec/spec_helper.rb

    Rspec.configure do |config|
  if config.filter_manager.inclusions[:visual]
    Capybara.javascript_driver = :selenium
    config.filter_manager.inclusions.delete(:visual)
  else
    Capybara.javascript_driver = :poltergeist
  end

~rest of rspec config code~

    Now you can run your tests with rspec (tests to run) -t visual
    The main problem with this is that it will prevent you from running specific tests. You can still do a single file with rspec spec/features/signup_spec.rb -t visual but you cannot add a :54 to run at a specific line number.
