Error for HTTP request made when no cassette is in use

VCR is designed to help you remove all HTTP dependencies from your
test suite. To assist with this, VCR will cause an exception to be
raised when an HTTP request is made while there is no cassette in
use. The error is helpful to pinpoint where HTTP requests are
made so you can use a VCR cassette at that point in your code.

If you want insight about how VCR attempted to handle the request,
you can use the debug_logger
configuration option to log more details.

If you want to allow an HTTP request to proceed as normal, you can
set the allow_http_connections_when_no_cassette
configuration option or you can temporarily turn VCR off:

  • VCR.turn_off! => turn VCR off so HTTP requests are allowed. Cassette insertions will trigger an error.
  • VCR.turn_off!(:ignore_cassettes => true) => turn VCR off and ignore cassette insertions (so that no error is raised).
  • VCR.turn_on! => turn VCR back on
  • VCR.turned_off { ... } => turn VCR off for the duration of the provided block.

Error for request when no cassette is in use
Given
a file named "no_cassette_error.rb" with:
include_http_adapter_for("http_lib")

require 'vcr'

VCR.configure do |c|
  configuration
  c.cassette_library_dir = 'cassettes'
end

response_body_for(:get, 'http://example.com/')
When
I run ruby no_cassette_error.rb
Then
it should fail with "An HTTP request has been made that VCR does not know how to handle"
Examples:
configuration http_lib
c.hook_into :fakeweb net/http
c.hook_into :webmock net/http
c.hook_into :webmock httpclient
c.hook_into :webmock curb
c.hook_into :webmock patron
c.hook_into :webmock em-http-request
c.hook_into :webmock typhoeus
c.hook_into :typhoeus typhoeus
c.hook_into :excon excon
c.hook_into :faraday faraday (w/ net_http)
Temporarily turn VCR off to allow HTTP requests to procede as normal
Given
a file named "turn_off_vcr.rb" with:
start_sinatra_app(:port => 7777) do
  get('/') { 'Hello' }
end

require 'vcr'

VCR.configure do |c|
  c.hook_into :webmock
end
WebMock.allow_net_connect!

def make_request(context)
  puts context
  puts Net::HTTP.get_response('localhost', '/', 7777).body
rescue => e
  puts "Error: #{e.class}"
end

VCR.turned_off do
  make_request "In VCR.turned_off block"
end

make_request "Outside of VCR.turned_off block"

VCR.turn_off!
make_request "After calling VCR.turn_off!"

VCR.turn_on!
make_request "After calling VCR.turn_on!"
When
I run ruby turn_off_vcr.rb
Then
the output should contain:
In VCR.turned_off block
Hello
And
the output should contain:
Outside of VCR.turned_off block
Error: VCR::Errors::UnhandledHTTPRequestError
And
the output should contain:
After calling VCR.turn_off!
Hello
And
the output should contain:
After calling VCR.turn_on!
Error: VCR::Errors::UnhandledHTTPRequestError
Turning VCR off prevents cassettes from being inserted
Given
a file named "turn_off_vcr_and_insert_cassette.rb" with:
require 'vcr'

VCR.configure do |c|
  c.hook_into :webmock
end
WebMock.allow_net_connect!

VCR.turn_off!
VCR.insert_cassette('example')
When
I run ruby turn_off_vcr_and_insert_cassette.rb
Then
it should fail with "VCR is turned off. You must turn it on before you can insert a cassette."
Turning VCR off with `:ignore_cassettes => true` ignores cassettes
Given
a file named "turn_off_vcr_and_insert_cassette.rb" with:
start_sinatra_app(:port => 7777) do
  get('/') { 'Hello' }
end

require 'vcr'

VCR.configure do |c|
  c.cassette_library_dir = 'cassettes'
  c.hook_into :webmock
end
WebMock.allow_net_connect!

VCR.turn_off!(:ignore_cassettes => true)

VCR.use_cassette('example') do
  response = Net::HTTP.get_response('localhost', '/', 7777).body
  puts "Response: #{response}"
end
When
I run ruby turn_off_vcr_and_insert_cassette.rb
Then
it should pass with "Response: Hello"
And
the file "cassettes/example.yml" should not exist
