locust-load-testing

Locust tests are Python classes inheriting from HttpUser; each @task-decorated method is an action a virtual user can take (locust-quickstart). Workflow: write locustfile.py, run locust, observe the live dashboard or run headless for CI.

When to use

• The project's primary stack is Python - load tests live in the same language as the application.
• The team wants programmatic test logic that's hard to express in declarative DSLs (e.g. branching based on response content, custom auth flows, Redis / queue interactions).
• Distributed load is a requirement - Locust's master / worker pattern is straightforward.
