What type of testing should be performed to ensure that a new input field for item quantity only accepts valid integers?

• A. Functional Testing
• B. Negative Testing
• C. Performance Testing
• D. Load Testing

Answer: (B)

The type of testing that should be performed to ensure that a new input field for item quantity only accepts valid integers is negative testing. Negative testing involves inputting invalid data or unexpected values to verify that the system responds correctly and prevents such entries. In this context, the focus is on checking how the application reacts when it receives non-integer values, such as letters, special characters, or decimal numbers. This helps ensure that the input validation is robust and that users can only provide acceptable data, enhancing the integrity of the system. Functional testing, on the other hand, focuses on verifying that the application functions as intended with valid inputs, but does not specifically address the handling of invalid data. Performance testing measures how an application behaves under load and its responsiveness, while load testing evaluates the system's capability to handle expected user traffic. Neither performance nor load testing is intended to validate input data integrity directly.
