gatlingUsing Gatling’s CSV Feeder to Drive Real‑World Load Tests
Learn how Gatling’s CSV feeder injects real data into virtual users, enabling realistic load tests. The article covers setup, usage, debugging, trade‑offs, and a step‑by‑step example.
Does Gatling reset CSV feeder state between repeated simulation runs?
Goal Execute the same Gatling 3.x simulation repeatedly inside one Maven, SBT, or Gradle session without restarting the build tool, while keeping CSV feeder records available on every run. Uncertainty Gatling feeders behave as iterators: each record is consumed once per feeder instance and is not automatically restored when the simulation runs again. If the
