To add a collaborator to this project you will need to use the Relish gem to add the collaborator via a terminal command. Soon you'll be able to also add collaborators here!
More about adding a collaborator:once
The :once
record mode will:
- Replay previously recorded interactions.
- Record new interactions if there is no cassette file.
- Cause an error to be raised for new requests if there is a cassette file.
It is similar to the :new_episodes
record mode, but will prevent new,
unexpected requests from being made (i.e. because the request URI changed
or whatever).
:once
is the default record mode, used when you do not set one.
- Background
-
- Given
-
a file named "setup.rb" with:
start_sinatra_app(:port => 7777) do get('/') { 'Hello' } end require 'vcr' VCR.configure do |c| c.hook_into :webmock c.cassette_library_dir = 'cassettes' end
- And
-
a previously recorded cassette file "cassettes/example.yml" with:
--- http_interactions: - request: method: get uri: http://example.com/foo body: encoding: UTF-8 string: "" headers: {} response: status: code: 200 message: OK headers: Content-Length: - "20" body: encoding: UTF-8 string: example.com response http_version: "1.1" recorded_at: Tue, 01 Nov 2011 04:58:44 GMT recorded_with: VCR 2.0.0
- Scenarios
-
- Previously recorded responses are replayed
- New requests result in an error when the cassette file exists
- New requests get recorded when there is no cassette file
- Previously recorded responses are replayed
-
- Given
-
a file named "replay_recorded_response.rb" with:
require 'setup' VCR.use_cassette('example', :record => :once) do response = Net::HTTP.get_response('example.com', '/foo') puts "Response: #{response.body}" end
- When
-
I run
ruby replay_recorded_response.rb
- Then
- it should pass with "Response: example.com response"
- New requests result in an error when the cassette file exists
-
- Given
-
a file named "error_for_new_requests_when_cassette_exists.rb" with:
require 'setup' VCR.use_cassette('example', :record => :once) do response = Net::HTTP.get_response('localhost', '/', 7777) puts "Response: #{response.body}" end
- When
-
I run
ruby error_for_new_requests_when_cassette_exists.rb
- Then
- it should fail with "An HTTP request has been made that VCR does not know how to handle"
- New requests get recorded when there is no cassette file
-
- Given
-
a file named "record_new_requests.rb" with:
require 'setup' VCR.use_cassette('example', :record => :once) do response = Net::HTTP.get_response('localhost', '/', 7777) puts "Response: #{response.body}" end
- When
- I remove the file "cassettes/example.yml"
- And
-
I run
ruby record_new_requests.rb
- Then
- it should pass with "Response: Hello"
- And
- the file "cassettes/example.yml" should contain "Hello"
