What Is Negative Testing?
Blog post from Keploy
Negative testing, also known as error path or failure testing, is a crucial software testing technique aimed at ensuring applications handle invalid, unexpected, or malicious inputs without crashing or producing erroneous results. Unlike positive testing, which verifies a system's functionality under normal conditions, negative testing challenges the software to maintain stability and reliability under adverse conditions, such as user errors or improper use. This type of testing is vital for uncovering edge cases, enhancing security by preventing input-based attacks like SQL injection, and improving user experience through robust error handling. Negative testing is applicable across various applications and can be automated using tools like Selenium and Keploy. It should be integrated throughout the Software Development Life Cycle (SDLC) to ensure that software is resilient against unpredictable user behavior and adverse conditions, ultimately leading to the development of more reliable and secure products.
