Heroku: unable to connect to chromedriver 127.0.0.1:9515 when using Watir/Selenium

Question

This runs locally (without specifying driver_path), but not on Heroku.

Code:

Selenium::WebDriver::Chrome.driver_path = ENV[         


        

Answer 1

I've been struggling with this one for more than a few hours ....

It has been very frustrating to try to debug on Heroku CI. This ticket has helped me a lot to find a solution.

I had this piece of code in the spec_helper.rb that was causing trouble (for if it helps someone):

config.before(:each, type: :system, js: true) do
  driven_by :selenium_chrome_headless
end

It was bypassing all the capybara setup...
