Capybara and Javascript onbefoureunload

Question

I have a ask_a_question page with the onbeforeunload function to warn the user before leaving something unsaved (e.g. SO: P). I am testing it with a cucumber with capybara and webdriver, adding an @javascript tag because it uses a lot of javascript. The cucumber function 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 as soon as the test patches, Capybara (or WebDriver, I dunno) tries to reuse the same browser window for other tests, then an onbeforeunload warning pops up, which has sent the next test.

As my function does not close or exit the page itself. I don’t think it would be nice to add something to accept the warning. But honestly, I’m completely lost.

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

Thanx

Answer 1

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

You can put it in the cucumber after the 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 

Answer 2

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
