rspec-tag_matchers is a collection of RSpec matchers for testing Rails views. The matchers can match against any string containing HTML or any object whose to_s method returns a string containing HTML (this includes Nokogiri classes). They assume Rails conventions. For example, the has_form matcher looks for a hidden input named _method when testing a form's method.


describe "users/new.html.haml" do
  before(:each) do

  it { should have_form.with_verb(:post).with_action(user_path) }
  it { should have_checkbox.for(:user => :terms_of_service) }

Getting Started

  • Add rspec-tag_matchers to your Gemfile:

    group :test do
      gem "rspec-tag_matchers"
  • Add the tag matchers to the RSpec context. In spec_helper:

    RSpec.configure do |config|
      config.include RSpec::TagMatchers
  • Now you can use the tag matchers in your RSpec tests. The included matchers are documented here:


rspec-tag_matchers is tested against Ruby 1.8.7, 1.9.2, 1.9.3, REE, Rubinius (1.8 and 1.9 modes) and JRuby.

The library is well tested, but the collection of matchers is incomplete. I'm adding more on an as-needed basis. Please feel free to fork this repository to add your own then send me a pull request.

Contributing to rspec-tag_matchers

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet

  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it

  • Fork the project

  • Start a feature/bugfix branch

  • Commit and push until you are happy with your contribution

  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.

  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
