Fast, Reliable. Pick Two
Continuously Build, Test, and Integrate our Code and Environments
- Build and test processes run constantly, independent of coding.
- This ensures that we understand and codify all dependencies.
- This ensures repeatable deployments and configuration management.
- Once changes make it into source control, the packages and binaries are created only ONCE. Those same packages are used throughout the rest of the pipeline to ensure all environments are receiving the same bits.
- What does this mean for our team culture?
- You need to maintain reliable automated tests that truly validate deploy-ability.
- You need to stop the "production pipeline" when validation fails, i.e. pull the andon cord.
- You need to work in small, short lived batches that are based on trunk. No long-lived feature branches.
- Short, fast feedback loops are necessary; builds on every commit.
Integrate Performance Testing into the Test Suite
- Should likely build the performance testing environment at the beginning of the project so that it can be used throughout.
