1. Noun:
   • A test measuring how a system functions when subjected to controlled amounts of stress: A "stress test" is an evaluation designed to assess the stability, performance, and limits of a system by deliberately applying pressure, demand, or adverse conditions beyond normal operational levels.

Usage

• The primary use of "stress test" is as a noun to describe a specific type of performance or stability evaluation.
• It is commonly used in fields like finance, engineering, computing, and medicine.
• It often appears in contexts discussing preparedness, resilience, and failure points.

• Load Test: A type of test that evaluates performance under expected load conditions (often a component of a broader stress test).
• Pressure Test: Commonly used in engineering to check for leaks or structural failure under pressure.
• Resilience Testing: A broader category of testing for recovery and stability under stress.
