What's your value proposition for snapshots and why can't that already be fulfilled with full body checks? https://github.com/Orange-OpenSource/hurl?tab=readme-ov-file...
TIL! The way I knew to do it was to have a mock implementation that behaved like the real thing, expect for data/time/uuids/..., where there was just a placeholder. Snapshot tests being able to "mask" those non-deterministic parts sounds cool!
