Description: Negative testing is a fundamental concept in test-driven development (TDD), referring to a test designed to ensure that a system behaves as expected when given invalid input. This type of testing is crucial for validating the robustness and security of an application, as it helps identify how the system handles unexpected or erroneous situations. Negative tests help prevent errors and vulnerabilities, ensuring that the software not only works correctly under ideal conditions but also manages errors appropriately. By implementing negative tests, developers can anticipate and mitigate issues that may arise in real-world software use, thereby improving user experience and system reliability. In summary, negative testing is an essential tool in any developer’s arsenal seeking to create solid and secure applications, ensuring that the software meets functional requirements while also being resilient to invalid inputs and adverse conditions.
