An alternate approach involves using VCR.py, a tool that records HTTP interactions in YAML files, then intercepts future HTTP requests and plays back the recorded responses. In this tutorial, we will use pytest-vcr to interface with VCR.py, although pytest-recording is another good option for doing the same.
