How to write a test to specify the format of a http request in ruby?

Question

I am writing a gem and I want to check that it is performing an http request with the parameters , headers and content that its supposed to pass. How do I write a unit test.

I am using httparty to do the request, I am also using fakeweb to test actions after the response.

I recommend using webmock and include the stub request that should be created:

In your Gemfile:

group :test do
  gem 'webmock'
end

In your spec:

stub_request(:post, 
             "https://external.api.com")
             .with(:body => {:message => {:foo => 'bar'}}, 
                  :headers => {'Accept'=>'application/json'})
