- Unit tests must be run and pass
- New tests must cover the newly added code

In a serverless system, there aren't many special considerations when talking about CI. Pair programming, unit testing, and test coverage are ideas that are not unique to any particular architecture. However, there are a few tricks to setting up serverless application code that make testing easier and even fun. I'll discuss some specific scenarios and ...
