Use AutoCorrelation in Test Controller Use AutoCorrelation in Test Controller AutoCorrelation helps identify dynamic values that must be captured and reused for a performance test to replay correctly. Use it during script validation before increasing load. When to review correlation Requests fail after login, checkout, search, or session creation. The application returns tokens, IDs, or timestamps that change each run. A script works once but fails on replay or under load. Recommended workflow Run a small validation execution. Review failed requests and dynamic response values. Apply correlation rules only to values required by later requests. Replay and verify the script before scaling. Last updated: September 18, 2026
