Description: Failure testing is a critical approach in software evaluation that focuses on how a system behaves under adverse or failure conditions. These tests simulate situations where the software might encounter errors, such as loss of network connection, lack of system resources, or incorrect data input. The primary goal is to identify vulnerabilities and ensure that the system can adequately handle errors while maintaining data integrity and service continuity. Failure testing is essential to ensure that the software is robust and reliable, as it allows developers to anticipate problems and design effective solutions. This type of testing not only assesses the system’s ability to recover from failures but also examines the user experience in error situations, ensuring that clear and helpful messages are provided. In a world where reliance on technology is increasing, failure testing has become an integral part of the software development lifecycle, helping organizations minimize risks and improve the quality of the final product.
