Which type of testing verifies the application's performance under load?

• A. Unit testing
• B. Integration testing
• C. Load testing
• D. User acceptance testing

Answer: (C)

Load testing is specifically designed to verify how an application performs under various conditions, particularly when subjected to expected and unexpected loads. It evaluates the system's behavior under heavy traffic and helps identify any bottlenecks or limits regarding the number of users or transactions the application can handle simultaneously. The goal of load testing is to ensure that the application remains stable and performs well, even when stress tested with high data volume or user requests. By simulating multiple users accessing the application at the same time, load testing helps in assessing response times, resource usage, and overall performance metrics. In contrast, unit testing focuses on individual components or functions of the application to ensure they work as intended in isolation. Integration testing checks the interaction between different modules of the application to find issues that could arise from their integration. User acceptance testing is conducted to ensure that the application meets business requirements and is acceptable to end-users but does not specifically measure performance under load.
