What is an easy way to stub / dummy a restful web service?
I've found using Sinatra really useful for this sort of thing if you want to test the actual HTTP calling code. You can have a endpoint returning data in seconds. Very little Ruby knowledge required.
require 'sinatra'
require 'json'
get '/Person' do
content_type :json
{ :id => 345, :key2 => 'John Doe' }.to_json
end
Is all you would need to return a simple json object.
Mocky.io allows you to create stub endpoints and specify the data they return via public URLs.
Runscope (disclaimer, I'm a founder) allows you to capture a real request once, then replay back the response as needed via Response Playback URLs.
