Stop relying on manual graph reviews. Learn how to use k6 thresholds to automate API SLA validation and prevent performance regressions from hitting production.
Learn how to encode service‑level objectives as k6 thresholds and checks so load tests automatically fail when SLOs are breached, with a minimal script, trust boundaries, operational checks, failure modes, and design‑change triggers.
Learn how k6 thresholds let you embed SLA rules directly into load‑test scripts, automate PASS/FAIL decisions, and gate CI/CD pipelines with clear exit codes.
k6 runs each Virtual User in its own Goja runtime on a goroutine — great for I/O-bound load, dangerous for CPU-heavy scripts. An architecture note on sizing one generator correctly and knowing when to split.
Learn how to codify performance budgets as k6 thresholds, wire them into CI/CD for automated regression gates, and handle flakiness and statistical pitfalls.
Use ramping-vus stages and http_req_duration / http_req_failed thresholds to make k6 load tests repeatable and CI-gateable without manual inspection.
Learn how to compose realistic, multi-protocol load profiles in a single k6 script using scenarios and executors. Includes a worked example with HTTP, WebSocket, and gRPC flows, plus trade-offs like arrival-rate overshoot and graceful-stop cutoffs.
Learn how k6’s http.batch lets a single virtual user send multiple HTTP requests in parallel, with a worked example, trade‑offs, and verification steps.
Learn how to use k6 Thresholds to define automated pass/fail criteria for your performance tests, ensuring your SLAs are met before code reaches production.
