Need to have VCR-like functionality for more than just http? Wait no more. This gem allows you to record arbitrary method invocations from arbitrary objects.
require 'camcorder'
//Need recorder
recorder = Camcorder::Recorder.new('recordings.json')
imap = Camcorder::Proxy.new(recorder, Net::IMAP, imap_host, imap_port, imap_ssl, nil, false)
imap.login(username, decrypted_password)
imap.search(query)
imap.disconnectThe above code will create an actual Net::IMAP object the first time around. Subsequent invocations will not, instead using recorded values.
For convenience, Camcorder provides a way to intercept the constructor for a class:
require 'camcorder'
Camcorder.intercept_constructor(Net::IMAP)
imap = Net::IMAP.new(imap_host, imap_port, imap_ssl, nil, false)
imap.login(username, decrypted_password)
imap.search(query)
imap.disconnectBy default, Camcorder matches up a method invocation to a recording based on the passed in arguments. Methods with side effects need to be explicitly noted:
require 'camcorder'
Camcorder.intercept_constructor(Net::IMAP) do
methods_with_side_effects :examine, :select
end
imap = Net::IMAP.new(imap_host, imap_port, imap_ssl, nil, false)
imap.login(username, decrypted_password)
imap.select('INBOX')
imap.search(query)
imap.select('Sent Items') # will cause the `search` call below to return a different value
imap.search(query)
imap.disconnectAdd this line to your application's Gemfile:
gem 'camcorder'And then execute:
bundle
Or install it yourself as:
gem install camcorder
In your spec_helper.rb file:
require 'camcorder/rspec'
