Feature Toggle

Programming technique in modern software development in which a feature or functionality under development can be switched on or off at runtime of the software. The development team or the developer switches on the feature at runtime in their own environment in order to be able to extend and test it. When the source code is checked into the integration, the feature toggle remains switched off by default until it has reached an acceptable level of maturity so that other teams, test teams or even users can work with it.
