What is the primary purpose of simulation in testing?

The primary purpose of simulation in testing is to demonstrate solutions or solution components. This process allows stakeholders to visualize how a system or component will function in a real-world scenario without having to implement the entire system first. By creating a simulated environment, analysts and developers can explore various functionalities, assess the feasibility of solutions, and make necessary adjustments before moving forward with development.

Simulations can provide valuable insights by allowing users to interact with a model that behaves like the final system. This helps in validating requirements, exploring the impacts of changes, and ensuring that the proposed solutions meet the needs of the users effectively. It is particularly useful in complex systems where real-life testing may be impractical or costly.

The other options, while relevant in their own right, do not align directly with the primary function of simulation in testing. Ensuring user satisfaction, analyzing database performance, and creating visual prototypes each serve different purposes in the development and testing lifecycle.
