Setting up VCR and Webmock for Cucumber Testing

In order to setup VCR and webmock for Cucumber testing you should:

Add webmock and VCR gems to your Gemfile.rb:

#Gemfile.rb
group :test do
  gem 'webmock'
  gem 'vcr'
end

Add file called vcr_setup.rb in your /features/support/ folder that will be used for VCR configuration.

# features/support/vcr_setup.rb
require 'vcr'
VCR.configure do |c|
  c.cassette_library_dir = 'features/cassettes'
  c.hook_into :webmock
  c.ignore_localhost = true
end
VCR.cucumber_tags do |t|
  t.tag '@vcr', :use_scenario_name => true
end

Add require ‘webmock/cucumber’ to /features/support/env.rb.

# features/support/env.rb
require 'webmock/cucumber'

Now, run your tests!

Your tests are now behaving like they are in a bubble: totally independent from their environment. If some of them worked, but now they are failing, that is because they are trying to make an API call.
To fix them just add @vcr to the top of the tests. Now the API call will be allowed, and it will be recorded saved in features/cassettes and later reused whenever there is an API call from that test.

Happy testing!
