I was working in a particular feature today. I wanted to test an autocomplete input box that makes its requests via Ajax. Something very common.
I wanted to test that the requests were being done to the right URL in a black box kind of way using the cucumber features.
This is what I did:
First added a new visit method
visit_tracking_ajax
to my Cucumber environment with the following contentmodule CucumberGlobals def visit_tracking_ajax(url) visit(url) page.execute_script("$(document).ajaxSuccess(function(a,b,c){console.log(this);window._latest_ajax_url_called = c.url;})") end end World(CucumberGlobals)
This executes a Javascript Jquery script in the page that will listen to every Ajax request being made (through Jquery) and set a variable on window
with the URL called in that request.
Then from my step definition I did something like:
page.latest_ajax_url.should == 'http://www.xx.xxx'
Having also added the following method to the Capybara session:
module CustomMethods def latest_ajax_url evaluate_script("window._latest_ajax_url_called") end end module Capybara class Session include CustomMethods end end
That's it, now I was checking the last ajax url being called. This is fragile code, but it worked fine for my current use case.
