Model–view–controller is a software design pattern commonly used for developing user interfaces that divide the related program logic into three interconnected elements.
Model The Model component corresponds to all the data-related logic that the user works with. This can represent either the data that is being transferred between the View and Controller components or any other business logic-related data. For example, a Customer object will retrieve the customer information from the database, manipulate it and update it data back to the database or use it to render data.
View The View component is used for all the UI logic of the application. For example, the Customer view will include all the UI components such as text boxes, dropdowns, etc. that the final user interacts with.
Controller Controllers act as an interface between Model and View components to process all the business logic and incoming requests, manipulate data using the Model component and interact with the Views to render the final output. For example, the Customer controller will handle all the interactions and inputs from the Customer View and update the database using the Customer Model. The same controller will be used to view the Customer data.
Role-based access control (RBAC) is a policy-neutral access-control mechanism defined around roles and privileges.

Test-driven development is a software development process relying on software requirements being converted to test cases before software is fully developed. here
Heroku app is already configured to this repository for automatic deploys from any push to the master branch. Create a pull request containing your respective changes and wait for merge.
Coverage is a tool for measuring code coverage of Python programs. It monitors your program, noting which parts of the code have been executed, then analyzes the source to identify code that could have been executed but was not. Docs
Continuous integration automates the building, testing and deploying of applications. Software projects, whether created by a single individual or entire teams, typically use continuous integration as a hub to ensure important steps such as unit testing are automated rather than manual processes.
Great businesses depend on great software. No matter the size of your team, choose CircleCI's CI/CD platform to automate confidence in your code.
