Week 2 Lecture

Continuous Integration is a software development practice
where members of a team integrate their work frequently.
Each integration is verified by an automated build (including test) to detect integration errors as quickly as possible.
When CI works well, it helps the code stay robust enough that customers and other stakeholders can play with the code whenever they like.
Like refactoring, continuous integration works well if you have an exhaustive suite of automated unit tests that ensure that you are not committing buggy code.
