How can I see what capybara found in a failing cucumber step?
Solution 1
Try adding this step:
Then show me the page
Solution 2
Then show me the page
calls webrat/capybara's underlying save_and_open_page
method. Found that useful when working with steak.
Solution 3
If you want to have the browser open the page when the page fails you use the 'launchy' gem. Add it to your gem file, and then in /features/support create a file called debugging.rb with contents:
After do |scenario|
save_and_open_page if scenario.failed?
end
Solution 4
If you're using Javascript or Ajax in your pages and want to see what's going on, I've found that the Poltergeist driver is very good at letting you get into the DOM and find out what's going wrong.
If you setup your Capybara driver with the remote debugging option:
Capybara.register_driver :poltergeist do |app|
Capybara::Poltergeist::Driver.new(app, inspector: true)
end
You can then put the following line in your steps:
page.driver.debug
Which fires up a new Chromium browser with the current DOM state set, letting you get at the console. (On my version of Linux, I had to symlink chromium to chromium-browser but it otherwise worked fine).

Solution 5
Then show me the response
didn't work for me with cucumber 1.1. I found useful to write a step using capybara's command:
print page.html
This outputs the current state of the DOM

I started migrating from cucumber + webrat to cucumber + capybara. Now the behavior of "I should see " seems to be somewhat different. Most of these fail now, although I didn't change anything on the page. I replaced the snippet that should be found with some stuff that is on every page and for some text it works and for other text it doesn't. I can't find any pattern in what is found in the page's content and what is not. Webrat used to print what the page content is that it found, in case it did not contain the required phrase. Is there anyway to have capybara show what text it got from the page in which it tried to find the text?

Dan Kohn over 9 yearsThis is spectacularly useful, thanks. It seems like it should be installed by default with Cucumber.

rii over 7 yearsI know this is super old, but after adding that directive I had to install the gem 'launchy' and it launched the page with the contents, truly great.
