Artillery is a performance testing tool. This post explains types of performance testing and dives into Artillery usage, from configuration to running tests and checking results. Load and stress testing Load and stress testing are two types of performance testing used to evaluate how well a system performs under various conditions. Load testing determines how the system performs under expected user loads. The purpose is to identify performance bottlenecks. Stress testing assesses how the system performs when loads are heavier than usual. The purpose is to find the limit at which the system fails and to observe how it recovers from such failures. Prerequisites Artillery available via npx (or installed in project dev dependencies) YAML config file that defines target, phases and scenarios Optional CSV payload file for dynamic test data Configuration Artillery test configuration is defined in a YAML file (for example, .artillery/main.yml ).…
