How can negative testing contribute to the quality assurance process in RSI Phase 5?

Negative testing plays a vital role in the quality assurance process, particularly in ensuring that systems are robust and resilient. When conducting negative testing, the focus is on validating how the system behaves under invalid conditions or when it encounters unexpected inputs. This type of testing helps identify potential vulnerabilities, edge cases, and failures that would not typically be uncovered through standard positive testing, which assumes that inputs will be valid.

Through negative testing, quality assurance teams can ascertain that:

1. The system reliably rejects invalid data, thereby preventing errors or crashes.

2. Appropriate error messages are displayed to users, enhancing user experience by guiding them on correct usage.

3. The system maintains security by not allowing malicious inputs to disrupt its functioning.

Overall, negative testing is crucial for building a robust application that can handle both typical and atypical use cases effectively. It ensures that the product not only meets functional requirements but is also safe and reliable in real-world scenarios.
