Testing destroy methods with capybara

StackOverflow https://stackoverflow.com/questions/5871437

Вопрос

I've written some tests using Capybara, but I'm not using selenium and neither any other JS drivers. But my doubt is if I can test a destroy method this way? Since I need to confirm a JS confirmation and the data-method = "delete" can't be visited...

I would like to do something very Capybara's way like:

visit '/people/123', :data-method => 'delete'

Do you guys know if is there some way to do that?

Thanks in advance, Andre

Rails has JavaScript code which generates a form from the link's href and data-method attributes and submits it; this won't work without JS.

One way to test this: first, test for the presence of the link and proper attributes (href, data-method), then trigger the delete request manually with the Capybara::RackTest::Driver#delete method. If you do this often, write a helper method wrapping those two steps.

Just something to be aware of with @Mike Mazur's answer, if your controller does a redirect on the #destroy action, invoking the delete method on Capybara's driver doesn't actually follow the redirect. Instead it just populates the response with the redirection message, i.e. body == <html><body>You are being <a href=\"http://www.example.com/model_names\">redirected</a>.</body></html> and status_code == 302.

So, to get everything populated like you would expect on a normal Capybara click_button 'Delete Model', you'll need to manually follow the redirect. One (unrefactored and RSpec flavored) way to do this:

Capybara.current_session.driver.delete controller_path(model_instance)
Capybara.current_session.driver.response.should be_redirect
visit Capybara.current_session.driver.response.location
