Requests per second, request latency, and overall system performance and reliability are some fundamental concepts that need to be taken into account when designing a high capacity API. With CI/CD becoming a common deployment methodology, deployments to production are a constant occurrence. How can we ensure that the core capabilities we initially designed our system with to have remained intact? We built Predator. It allows us to manage the entire lifecycle of stress-testing a server, from creating a test file, running scheduled and on-demand tests, and viewing test results. Its seamless integration with both NOSQL and SQL databases keep test results persistent. Bootstrapped with a user-friendly UI alongside a REST API, Predator helps developers simplify the performance testing regime.
