# About These Examples

The cucumber features provided here demonstrate all of the major features of VCR. These features are executable documentation for VCR.

Many of the examples use one (or both) of these helper functions provided by `spec/support/cucumber_helpers.rb`:

* `start_sinatra_app`: starts a sinatra application on the given port.

  The server automatically shuts down when the ruby script ends.  Many

  examples re-run the script without the sinatra server to demonstrate

  the replaying of a recorded HTTP response.
* `include_http_adapter_for`: includes a module that implements a common

  HTTP interface for the given HTTP library.  The `response_body_for`

  method will make an HTTP request using the given library.  This

  allows scenarios to be run against each different supported HTTP

  library.

If you have ideas to clarify or improve any of these cucumber features, please submit an [issue](https://github.com/vcr/vcr/issues) or pull request.
