Record on Error
The :record_on_error
flag mode will prevent a cassette from being recorded when the code that uses the cassette (a test) raises an error (test failure).
Background ()
Given a file named "setup.rb" with:
$server = start_sinatra_app do
get('/') { 'Hello' }
end
require 'vcr'
VCR.configure do |c|
c.hook_into :webmock
c.cassette_library_dir = 'cassettes'
end
Requests are recorded when no error is raised
Given a file named "record_when_no_error.rb" with:
require 'setup'
VCR.use_cassette('example', :record_on_error => false) do
response = Net::HTTP.get_response('localhost', '/', $server.port)
puts "Response: #{response.body}"
end
When I run ruby record_when_no_error.rb
Then it should pass with "Response: Hello"
And the file "cassettes/example.yml" should contain "Hello".
Requests are not recorded when an error is raised and :record_on_error is set to false
Given a file named "do_not_record_on_error.rb" with:
require 'setup'
VCR.use_cassette('example', :record => :once, :record_on_error => false) do
Net::HTTP.get_response('localhost', '/', $server.port)
raise StandardError, 'The example failed'
end
When I run ruby do_not_record_on_error.rb
Then it should fail with "The example failed"
And the file "cassettes/example.yml" should not exist.
Requests are recorded when an error is raised and :record_on_error is set to true

end
When I run ruby record_on_error.rb
Then it should fail with "The example failed"
But the file "cassettes/example.yml" should contain "Hello".
