how to click on a table row using capybara & rspec - ruby-on-rails-3

Question

I am writitng request spec for my rails app with capybara. In my code I have something like:
%table
%tbody
%tr{"on_click" => "location.href='some_link'"}
%td="Some attribute"
%td="Some attribute"
%td="Some attribute"
%td="Some attribute"
This way I make the entire row clickable. I want to write a request spec with capybara for this feature but I don't know how. Can anyone help me on this ?
Thank you

Answer 1

May be you should first get to know the testing in rails. Check this out! http://railscasts.com/episodes/275-how-i-test it is really helpful. You can give your tr a class (say) .tr and do
page.find(:css, ".tr").click()
I hope this works, worked in my case!

I found this works without requiring a class:
page.find(:xpath, "//table/tbody/tr").click
I believe your row-click requires JavaScript, so you'll need to add :js => true to your test's header. Setting up testing with JavaScript is a challenge. I found these resources helpful:
ASCIIcast #257 Request Specs and Capybara - see info on database-cleaner
Capybara readme - see “Transactions and Database Setup"
Here is a more complete test example:
# Note that opening page by clicking on row requires JavaScript
describe "when user clicks on first row", :js => true do
let(:first_account_listed) { Account.order(:name).first }
before { page.find(:xpath, "//table/tbody/tr").click }
it { should have_selector('title', text: 'Account Details') }
end

In Capybara 3+ you can go with a more elegant way by using the :table_row selector and match against a td value like:
page.find(:table_row, ["Some attribute"]).click
If you have table headers defined you can also pass a Hash instead of an Array that will match the cell against its corresponding table header like this:
page.find(:table_row, { "Header" => "Cell value" }).click
To dive into how this actually works, here's a link to the latest Capybara selector definition: https://github.com/teamcapybara/capybara/blob/master/lib/capybara/selector/definition/table_row.rb
