As we all know, software developers may ease their development process by integrating their work as often as they can. It is also known that releasing frequently into production helps a lot. But developers and project stakeholders don’t want to expose half-developed features to their users. So, what happens in this case?
A useful technique to deal with this issue is to build the backend, integrate, but don’t build the user interface. The feature can be integrated and tested, but the UI is held back with the help of a keystone ( more info you may find in Martin Fowler’s blog ) and added only when the feature is completed, showing it to the users.
