APIs pass tests. CI is green. Everything looks fine. But production still breaks — not because of complex bugs, but because of simple things nobody tested.
👉 missing auth
👉 invalid inputs
👉 unexpected formats
👉 edge cases that never made it into tests
The article explains this gap really well — between “what we test” and “what actually breaks”. That’s exactly where Rentgen sits:
👉 not replacing tests
👉 but showing what you didn’t think to test
Paste one request → see what breaks.
