What is the MVC design pattern and how is it implemented in Rails?MVC stands for Model-View-Controller. It is a design pattern that separates the data (model), presentation (view), and logic (controller) layers of a web application. This makes for more modular and maintainable code.

To run a task from your Rakefile, you would use the rake command followed by the name of the task. For example, to run the tests defined in the above Rakefile, you would use the following command: rake test .
