Stopping Flaky CI: Using k6 Thresholds for API SLA Validation
Stop relying on manual graph reviews. Learn how to use k6 thresholds to automate API SLA validation and prevent performance regressions from hitting production.
k6Scaling to Thousands of Users: Understanding Gatling's Asynchronous Architecture
Learn how Gatling's asynchronous architecture overcomes the thread-per-user bottleneck to simulate thousands of concurrent users without crashing your injector.
gatlingLoad Testing Real-Time Apps with Gatling's WebSocket Support
Load testing real-time applications requires WebSocket support. Gatling's built-in WebSocket simulation handles bidirectional communication for chat apps, live dashboards, and collaborative tools with memory-efficient non-blocking I/O.
Using k6 Thresholds and Checks to Enforce Service‑Level Objectives in Load Tests
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.
Using Gatling Feeders and Checks to Avoid Skewed Load‑Test Results
Learn how to feed each virtual user unique data from a CSV and validate responses with Gatling checks so your load test reflects real‑world behavior.
Using k6 Thresholds to Automate SLA Validation in Load Tests
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.
Designing Around k6's Virtual User Model: When One Generator Is Enough
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.
Using Gatling CSV Feeders to Drive Realistic Load Tests
Learn how to load dynamic data from a CSV file into Gatling simulations, choose the right feeder strategy, and verify the behavior without risking memory overload.
