The practice of continuous integration and continuous implementation, i.e. Continuous Integration (CI) and Continuous Delivery (CD), used in work on building and developing IT projects. Its goal is to create a coherent and automated process of building and testing the application, and at a later stage its implementation and service. Thanks to this practice, where any code changes are updated regularly in small intervals, teams do not waste time on routine tasks related to compiling, testing and distributing code.
