ResponseCodeMatchers Build Status

Provide rspec matchers to match http response code.
The receiver of this matcher should have #code or #status method which returns http status code, and #header and #headers methods.

Installation

$ gem install response_code_matchers

Usage

In Rails example:

# spec/spec_helper.rb
require "response_code_matchers"

RSpec.configure do |config|
  config.include ResponseCodeMatchers
end
# spec/controllers/blogs_controller.rb
describe BlogsController do
  describe "#create" do
    subject do
      post :create, params
    end

    let(:params) do
      { :title => "title", :body => "body", :token => "token", :user_id => 1 }
    end

    # 201
    context "with valid token" do
      it { should be_created }
    end

    # 400
    context "without user_id" do
      before do
        params.delete(:user_id)
      end

      it { should be_bad_request }
    end

    # 401
    context "with invalid token" do
      before do
        params[:token] = "invalid"
      end

      it { should be_unauthorized }
    end
  end
end

Advantage

Rack::Response has predicative methods like #not_found?, #bad_request?, and etc. so we can use response.should be_not_found without this gem.

There are 2 advantages to use this gem.

  1. The range of differences that Rack::Response does not have
  2. Useful failure messages for each failed reason
# without response_code_matchers.gem
expected not_found? to return true, got false

# with response_code_matchers.gem
expected response code to be 404, but 400
