A Negative Scenario is a test case designed to identify potential failures or errors in a system. They ensure that the system can handle unexpected inputs or conditions. These scenarios help verify the robustness of software by testing how it behaves under adverse situations.
Key Characteristics:
- Focus on invalid or unexpected inputs.
- Aim to uncover weaknesses in the system.
- Help ensure proper error handling.
- Validate system stability under stress.
Examples:
- Entering invalid data types in input fields.
- Submitting forms with missing required information.
- Testing system responses to extreme values (e.g., maximum character limits).
- Simulating network failures during transactions.
Negative scenarios are essential for comprehensive testing. They complement positive scenarios, which test expected behaviours. By including negative scenarios, teams can improve software quality and user experience.
