Endurance testing is a type of performance evaluation that assesses how well a system, application, or component can handle prolonged use under specific conditions. This testing helps identify potential weaknesses or failures that may occur over time, ensuring that the product can maintain its functionality and performance levels during extended periods of operation. Typically used in software development, endurance testing focuses on factors such as response time, resource consumption, and stability. By simulating real-world usage scenarios, developers can gather valuable data to improve the reliability and efficiency of their products, ultimately enhancing user experience and satisfaction.
