For a Cucumber scenario on my Rails 3.1 app, I used the @javascript tag, so Selenium is activated. I get the following error:

Could not find Firefox binary (os=macosx). Make sure Firefox is installed or set the path manually with Selenium::WebDriver::Firefox::Binary.path= (Selenium::WebDriver::Error::WebDriverError)

If possible, I'd like to use Google Chrome as the browser - not Firefox (which I haven't installed). Is this possible? What could be done?

In fact, shouldn't Cucumber/Selenium detect a browser and use it?


After adding

Capybara.register_driver :selenium do |app|, :browser => :chrome)

end features/support/env.rb, I now get this error:

Unable to find the chromedriver executable. Please download the server from and place it somewhere on your PATH. More info at (Selenium::WebDriver::Error::WebDriverError)

  ./features/step_definitions/web_steps.rb:45:in `/^(?:|I )am on (.+)$/'

  features/update_memories.feature:11:in `Given I am on the home page'

I've downloaded from here, and I've tried putting the chromedriver executable in /usr/bin, but I still get the above error.

====EDIT 2====

After going one step further and running "sudo chmod +x /usr/bin/chromedriver" as suggested below, I now get a new error after running cucumber:


  Scenario: navigate to memory update page from home page              # features/update_memories.feature:11

    Given I am on the home page                                        # features/step_definitions/web_steps.rb:44

      unable to connect to chromedriver (Selenium::WebDriver::Error::WebDriverError)

      ./features/step_definitions/web_steps.rb:45:in `/^(?:|I )am on (.+)$/'

      features/update_memories.feature:12:in `Given I am on the home page'

    When I activate the edit memory switch for the memory "I played"   # features/step_definitions/memories/memory_steps.rb:5

    Then I should be on the edit memory page for the memory "I played" # features/step_definitions/web_steps.rb:187

      PGError: server closed the connection unexpectedly

        This probably means the server terminated abnormally before or while processing the request.

      : ROLLBACK (ActiveRecord::StatementInvalid)

Any help is appreciated!

For capybara, add this to env.rb

app|, :browser => :chrome) end

Download the Chrome driver executable and copy it in your path, e.g. /usr/bin/ and make it executable using this:

$ sudo chmod +x /usr/bin/chromedriver
