Awarded for completing Testing Generated Code: Coverage, Property Tests and Fuzzing and passing its exam, demonstrating the ability to detect a tautological test, read a suite for what it would catch rather than for its coverage number, choose and run properties that hold independently of an implementation, target fuzzing at the input handling that warrants it, close error and edge handling systematically, build regression tests from real defects, and rank testing effort by consequence and rate of change when retrofitting everything is not available.
Certificates are designed to be checked, not just displayed.
The credential is valid for 12 months from issue. Its public page states the expiry date, and renewing means passing the current exam again — so the credential always reflects the current material.
