default_cassette_options

The default_cassette_options configuration option takes a hash that provides defaults for each cassette you use. Any cassette can override the defaults as well as set additional options.

The :match_requests_on option defaults to [:method, :uri] when it has not been set.

The :record option defaults to :once when it has not been set.

Background ()

Given a file named "vcr_setup.rb" with:

require 'vcr'

VCR.configure do |c|
  c.default_cassette_options = { :record => :new_episodes, :erb => true }

  # not important for this example, but must be set to something
  c.hook_into :webmock
  c.cassette_library_dir = 'cassettes'
end

cassettes get default values from configured default_cassette_options

Given a file named "default_cassette_options.rb" with:

require 'vcr_setup.rb'

VCR.use_cassette('example') do
  puts "Record Mode: #{VCR.current_cassette.record_mode}"
  puts "ERB: #{VCR.current_cassette.erb}"
end

When I run ruby default_cassette_options.rb

Then the output should contain:

Record Mode: new_episodes
ERB: true

:match_requests_on defaults to [:method, :uri] when it has not been set

Given a file named "default_cassette_options.rb" with:

require 'vcr_setup.rb'

VCR.use_cassette('example') do
  puts "Match Requests On: #{VCR.current_cassette.match_requests_on.inspect}"
end

When I run ruby default_cassette_options.rb

Then the output should contain "Match Requests On: [:method, :uri]".

:record defaults to :once when it has not been set

Given a file named "default_record_mode.rb" with:

require 'vcr'

VCR.configure do |c|
  # not important for this example, but must be set to something
  c.hook_into :webmock
  c.cassette_library_dir = 'cassettes'
end

VCR.use_cassette('example') do
  puts "Record mode: #{VCR.current_cassette.record_mode.inspect}"
end

When I run ruby default_record_mode.rb

Then the output should contain "Record mode: :once".

cassettes can set their own options

Given a file named "default_cassette_options.rb" with:

require 'vcr_setup.rb'

VCR.use_cassette('example', :re_record_interval => 10000) do
  puts "Re-record Interval: #{VCR.current_cassette.re_record_interval}"
end

When I run ruby default_cassette_options.rb

Then the output should contain "Re-record Interval: 10000".

cassettes can override default options

Given a file named "default_cassette_options.rb" with:

require 'vcr_setup.rb'

VCR.use_cassette('example', :record => :none, :erb => false) do
  puts "Record Mode: #{VCR.current_cassette.record_mode}"
  puts "ERB: #{VCR.current_cassette.erb}"
end

When I run ruby default_cassette_options.rb

Then the output should contain:

Record Mode: none
ERB: false
