Continuous delivery (CD)

Continuous delivery is an extension of the principles behind continuous integration. It entails that the code is always in a state in which it is deployable. This practice leans heavily on the automation of the testing and delivery processes, to ensure that these happen without any hiccups. The testing happens in stages, where if the code passes one stage of tests, it automatically passes on to the next stage, and so on and so forth until the code is ready for deployment.

Continuous integration (CI)

By making it a practice to integrate code into the main branch of a shared repository as early and often as possible, continuous integration minimizes the cost of integration in a build process and allows for more frequent and automated testing. By kicking off automated tests as soon as a developer merges a new code, test suites can be run to check whether any new integration errors were introduced.
