An Introduction to Workflows Automation (CI,CT and CD) Continuous Integration : CI is a development practice where members of a team integrate their work frequently, with each integration being verified by an automated build to detect errors as quickly as possible. Continuous Testing : CT means that every time an integration is done predefined test cases are run to ensure that the new code doesn’t break the existing system. Continuous Deployment : CD means that you deliver software in continuous incremental fashion and deploy frequently. Here deploying could be to a test environment or pre-prod environments.
