VCR: Alternative way of mocking remote APIs

If you need to test interaction with a remote API, check out the VCR gem as an alternative to Webmock or stubbing hell.

The idea behind VCR is that is performs real HTTP requests and logs the interaction in a .yml file. When you run the test again, requests and responses are stubbed from the log and the test can run offline.

It's a great way to mock network requests to an external service without going through the pain of logging network traffic with Wireshark or similar tools.

By refactoring problematic code and creating automated tests, makandra can vastly improve the maintainability of your Rails application.
