MockMvc simulates HTTP requests without starting a server.
MockMvc is a tool from Spring that allows you to perform controller testing by simulating HTTP requests. It helps validate the behavior of your controllers and their responses without the need to deploy your application in a server environment. For instance, in an e-commerce platform, you can test adding a product to the cart by simulating a POST request to the '/cart' endpoint.
