Realistic Load Testing with Grafana k6

Grafana k6 is a free, open-source load-testing tool that can run locally and execute multiple concurrent scenarios to model real usage.

Do not send thousands of requests through a single account. Rate limiting and throttling may stop the test before it measures the system's real behavior. Create many users, distribute scenarios across different accounts and data, and make each path resemble how the product is actually used.

In Laravel, factories and seeders can generate test data whose size and shape are close to production. A predictable account-generation pattern also lets k6 use the prepared credentials. The closer the environment, data, and scenarios are to reality, the more useful the results become for performance and capacity decisions.
