Testing

I investigated customer reports about route adherence instead of starting with a code change. Production queries and staging reproductions exposed an overly broad diagnostic rule; after narrowing it, I used the evidence to guide targeted fixes. The counts describe different populations, and the post-release trend was a team measure rather than an isolated result of my work.

Turned a non-deterministic end-to-end suite (25 to 37 failures varying per run) into 302 passing with zero failures (8 pre-existing skips left untouched, and the consumer running), without adding a skip or weakening an assertion, and, in review, empirically proved that three of four proposed production changes were unnecessary.
