Introduction

In this tutorial we learn how to install ruby-vcr on Ubuntu.

What is ruby-vcr

ruby-vcr is:

Record your test suite’s HTTP interactions and replay them during future test runs for fast, deterministic, accurate tests.

• Automatically records and replays your HTTP interactions with minimal setup/configuration code.
• Supports and works with the HTTP stubbing facilities of multiple libraries. Currently, the following are supported:
  • WebMock
  • Typhoeus
  • Faraday
  • Excon
• Supports multiple HTTP libraries:
  • Patron (when using WebMock)
  • Curb (when using WebMock – only supports Curl::Easy at the moment)
  • HTTPClient (when using WebMock)
  • em-http-request (when using WebMock)
  • Net::HTTP (when using WebMock)
  • Typhoeus (Typhoeus::Hydra, but not Typhoeus::Easy or Typhoeus::Multi)
  • Excon
  • Faraday
  • And of course any library built on Net::HTTP, such as Mechanize, HTTParty or Rest Client
• Request matching is configurable based on HTTP method, URI, host, path, body and headers, or you can easily implement a custom request matcher to handle any need.
• The same request can receive different responses in different tests–just use different cassettes.
• The recorded requests and responses are stored on disk in a serialization format of your choice (currently YAML and JSON are built in, and you can easily implement your own custom serializer) and can easily be inspected and edited.
• Dynamic responses are supported using ERB.
• Optionally re-records cassettes on a configurable regular interval to keep them fresh and current.
• Disables all HTTP requests that you don’t explicitly allow.
• Simple Cucumber integration is provided using tags.
• Includes convenient RSpec macros and integration with RSpec 2 metadata.
• Known to work well with many popular Ruby libraries including RSpec 1 & 2, Cucumber, Test::Unit, Capybara, Mechanize, Rest Client and HTTParty.
• Includes Rack and Faraday middleware.
