stress test

This term originates from cardiology, where it describes a medical procedure to monitor heart performance during physical exertion. In modern usage, it has expanded into a broad technical metaphor used in finance, engineering, and software development to describe the process of pushing a system to its absolute limits to find the point of failure.

While a standard "test" checks if a system works under normal conditions, a "stress test" specifically seeks the breaking point. It carries a connotation of rigor and intentional provocation of failure to ensure resilience. In a corporate or financial context, it often implies a regulatory requirement rather than a voluntary check.
