Capybara and Javascript onbefoureunload

I have an 'ask_a_question' page with an onbeforeunload function to alert the user before leaving something unsaved (hey! like SO :P). I'm testing it using cucumber with capybara and webdriver, adding the @javascript tag because it uses a lot of javascript. A cucumber feature might look like this:

@javascript
Scenario: add a question
    Given I login as "Mauricio"
    And I go to the create question page 
    Then I should see "Ask a Question" within "header"

But once the test pases, Capybara (or WebDriver, I dunno) tries to reuse the same browser window for other tests then the onbeforeunload alert is displayed screwing the following test.

As my feature is not closing or exiting the page per se. I don't think it might be good idea to add something to accept the alert. But honestly I'm quite lost.

How can I tell capybara to use a new browser window for each @javascript test or automatically close the onbeforeunload alert?

Thanx

you can use page.driver.browser.switch_to.alert.dismiss (docs here) to get rid of the alert.

You could put this in a cucumber after hook

After "@javascript" do
  page.driver.browser.switch_to.alert.dismiss
  # or accept it if that is what you prefer
  page.driver.browser.switch_to.alert.accept
end

A similar answer for anyone using Rspec and Capybara. This code visits 'about:blank' after each test.

context 'page that displays an alert when navigating away' do

  after(:each) do
    begin
      accept_confirm { visit('about:blank') }
    rescue Capybara::ModalNotFound
      # For examples that don't end with an alert
    end
  end

  ...
end
