I had a bunch of combined controller\/view tests written with rspec. I added the Capybara gem and wrote some integrations tests which pass fine. The only problem is that now in all my controller tests, where I have<\/p>\n

response.should have_selector(“some selector”)<\/p>\n

rspec gives errors such as:<\/p>\n

NoMethodError:\n       undefined method `has_selector?' for #\n<\/code><\/pre>\n
when I run controller tests. I’m guessing that Capybara is being used in my controller tests and has overwritten some Rspec methods. How can I fix this?<\/p>\n
# gemfile.rb\ngroup :test do\n  gem 'rspec'\n  gem \"capybara\"\n  gem \"launchy\"\n  gem 'factory_girl_rails', '1.0'\nend\n\n# spec_helper.rb\nRSpec.configure do |config|\n  config.include IntegrationSpecHelper, :type => :request\nend\n<\/code><\/pre>\n
Here’s an example of a failing test:<\/p>\n
# spec\/controllers\/books_controller_spec.rb\nrequire 'spec_helper'\n\ndescribe BooksController do\n  render_views\n\n  it \"should have the right page title\" do\n    get :show, :id => @book.ean\n    response.should have_selector(\"title\", :content => \"Lexicase | \" + @book.title)\n  end\nend\n<\/code><\/pre>\n
and it’s associated error:<\/p>\n
  1) BooksController GET 'show' should have the right page title\n     Failure\/Error: response.should have_selector(\"title\", :content => \"Lexicase | \" + @book.title)\n     NoMethodError:\n       undefined method `has_selector?' for #\n     # .\/spec\/controllers\/books_controller_spec.rb:23:in `block (3 levels) in '\n<\/code><\/pre>\n
    \n
  1. \n
    You were probably using Webrat earlier, and has_selector?<\/strong> is a Webrat matcher. Capybaras doesn’t have a has_selector matcher, it has a matcher called has_css<\/strong>. You may want to replace the “has_selector” with “has_css”.<\/p>\n<\/li>\n
  2. \n
    Capybara helpers only works within requests specs. Either create a new request spec, or pass in :type => :request in the describe block part, like so:<\/p>\n
    describe \"test for the testing test\", :type => :request do\n  it \"should work with capybara\" do\n    visit root_path\n    click_link \"Home\"\n    page.should WHATEVA\n  end\nend\n<\/code><\/pre>\n
    I realize this question was asked a long time ago, but I thought I would share anyway. GLHF<\/p>\n<\/li>\n<\/ol>\n
