vcr-stub-server 0.1.2

Standalone stub server for replaying VCR cassettes

vcr-stub-server

This is a small tool for setting up a lightweight stub server that replays previously recorded VCR cassettes.

Usually VCR is used internally while running the test suite. In that case, the library is responsible for intercepting HTTP requests.

But in some cases, it can be useful to be able to spin up a live HTTP server which given a preexisting VCR cassette, would respond to each request with its matching recorded response.

One such case might come when implementing usage of Pact, where vcr-stub-server can be used to prevent the provider service from making requests to external services during pact verification. This project was inspired by Pact's own Stub Service.

Caveats

Unfortunately, there is no one standard for cassette YAML files, each VCR implementation is different. For example, cassette YAML files created by VCR.py won't be compatible with YAML files created by the Ruby implementation of VCR, etc.

Therfore this tool currently only supports VCR.py, using the library's own implementation of parsing the YAML files.

Installation

pip install vcr-stub-server

Usage

Once the package is installed, use the vcr-stub-server command to spin up your stub server.
