Feature: 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/debug-logging)
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/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.

Scenario Outline: Error for request when no cassette is in use
Given a file named "no_cassette_error.rb" with:
"""ruby
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) |
Scenario: Temporarily turn VCR off to allow HTTP requests to procede as normal
Given a file named "turn_off_vcr.rb" with:
"""ruby
start_sinatra_app(:port => 7777) do
get('/') { 'Hello' }
end
require 'vcr'
VCR.configure do |c|
c.hook_into :fakeweb
end
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
"""
Scenario: Turning VCR off prevents cassettes from being inserted
Given a file named "turn_off_vcr_and_insert_cassette.rb" with:
"""ruby
require 'vcr'
VCR.configure do |c|
c.hook_into :fakeweb
end
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."
Scenario: Turning VCR off with `:ignore_cassettes => true` ignores cassettes
Given a file named "turn_off_vcr_and_insert_cassette.rb" with:
"""ruby
start_sinatra_app(:port => 7777) do
get('/') { 'Hello' }
end
require 'vcr'
VCR.configure do |c|
c.cassette_library_dir = 'cassettes'
c.hook_into :fakeweb
end
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
