RSpec2 and Capybara

Question

Capybara is confusing me. If I use Capybara in combination with Ruby on Rails 3 and RSpec 2, then in RSpec request tests, the following matcher works:

respon         


        

Answer 1

So I just ran into similar, and this is I think what's going on:

It depends on code you didn't include here of how you visit the page. I'm writing an rspec request spec.

If I retrieve the page with rspec's own:

get '/some/path'

then response.body.should have_selector works as you say, but page.should does not.

To make Capybara 'page' work (and to make Capybara interactions like click_button or fill_in work), instead of retrieving with rspec's 'get', you need to retrieve with Capybara's 'visit':

visit '/some/path'
page.should have_selector("works")

'page', a capybara method, only gets set when using 'visit', a capybara method.

This does get confusing, all the mixing and matching of different libraries involved in rails testing.
