cl-vcr
This library is inspired by https://github.com/vcr/vcr
Record your TEST SUITE’S HTTP interactions and replay them during future test runs for fast, deterministic, accurate tests.
(prove:run :cl-vcr-tests) or (asdf:test-system :cl-vcr-tests)
As https://40ants.com/lisp-project-of-the-day/2020/09/0182-cl-vcr.html points out in a very nice way, this snippet is not robust at all.
CL-VCR is a good example of a really bad implementation of a nice idea :)
