VCR making real HTTP requests on Playback

[saagunda]

The URI hostname that gets recorded is an AWS box. And whenever this box is down, my tests fail on playback mode.

Hi, thanks for reporting this.
Are you able to share any sort of reproducible test case?

[saagunda]

@mcfiredrill Can you let me know what exactly would you need from me? The vcr.rb configurations or the test result output.

@saagunda

If you cannot share the test itself, could you write a new small test that reproduces it? The test file, along with the vcr configuration and the recorded vcr cassette would help alot.

This is my vcr config

require 'cucumber/rails'

def live_mode?
  ENV['LIVE_TESTS'] == '1'
end

def record_mode?
  ENV['RECORD'] == '1'
end

if live_mode?
  WebMock.allow_net_connect!
else
  # Dont make real http connections in test. Instead, expect VCR to be used.
  WebMock.disable_net_connect!
end

VCR.configure do |c|
  # Only make actual connections if live tests are enabled.
  c.default_cassette_options = { :record => (ENV['LIVE_TESTS'] == '1') ? :all : :new_episodes }
  c.hook_into :webmock

  # If we are running live tests but not recording their responses, use a cassettes
  # directory that's not checked into git to avoid saving bad responses, polluting
  # history, etc.
  if live_mode? && !record_mode?
    c.cassette_library_dir = 'tmp/cassettes'
  else
    c.cassette_library_dir = 'features/cassettes'
  end

  c.allow_http_connections_when_no_cassette = true
  c.ignore_localhost = true
  c.debug_logger = File.open("tmp/vcr.log", "w")
end

AfterStep('@live-only') do
  pending "This scenario can only run properly when LIVE_TESTS is enabled." unless live_mode?
end

Before('@vcr') do |scenario|
  if scenario.respond_to? :scenario_outline
    feature = scenario.scenario_outline.feature
  else
    feature = scenario.feature
  end

  cassette_name = "#{feature.name.split("\n").first}/#{scenario.name}"

  if record_mode? # Clean out the old one, since VCR will otherwise append.
    `rm 'features/cassettes/#{cassette_name.gsub(' ','_').gsub(',','')}.yml'`
  end

  aperture_matcher = lambda do |request_1, request_2|
    normalized_path_parts = lambda do |request|
      # Remove any part of the path that's numeric, and normalize.
      request.parsed_uri.path.split('/').reject(&:empty?).reject { |part| part.to_i > 0 }.compact.uniq.sort
    end

    normalized_path_parts.call(request_1) == normalized_path_parts.call(request_2)
  end

  VCR.insert_cassette(cassette_name, :erb => true, :allow_playback_repeats => true, :match_requests_on => [:method, aperture_matcher])
  #VCR.insert_cassette(cassette_name, :erb => true, :match_requests_on => [:method, :host, :uri, VCR.request_matchers.uri_without_param(:_)])
end

After('@vcr') do
  if record_mode? && live_mode?
    #pause to allow last requests to finish recording
    sleep(25)
  end
  VCR.eject_cassette
end
