Green Karate Tests Don't Guarantee Full API Coverage, Experts Warn

A passing Karate test suite with a 100% pass rate can still leave critical API operations untested, according to a technical analysis published on DEV Community. The article distinguishes between execution health — whether known tests pass — and contract coverage, which measures how many OpenAPI-defined operations have corresponding test evidence. Using an example where DELETE, PATCH, and a nested GET endpoint were entirely absent from a 184-scenario suite, the piece demonstrates how gaps remain invisible in standard CI reports. The author recommends mapping each HTTP method and normalized path from the OpenAPI contract against existing Karate scenarios to identify uncovered operations. Simple string matching is flagged as insufficient, with structural path normalization proposed as a more reliable approach to avoid false 'covered' results.
