Architecture & Systems
CI Pipeline and Test Gates
Continuous integration runs tests and checks on every change so broken code never reaches main.
Mental model
Every change should pass automated checks before it can change the shared analytical system.
A CI pipeline triggers automatically on each pull request and runs unit tests, linters, and other checks.
Failing checks act as gates: a red build blocks merges until issues are fixed or tests are updated intentionally.
Explore the mechanism
Which automated evidence must a change produce before it is allowed into the shared codebase?
- Checks are not “nice to have”. They are the merge contract.
- A red stage must block main. Otherwise CI is theatre.
- Keep PR checks short. Move slow coverage to scheduled runs, not to “never”.
What happens when a pricing-sign defect enters the branch?
What to notice
Short, fast pipelines give quick feedback, while slower integration tests can run nightly or on main to guard behaviour.
Where it appears
- running unit and integration tests on pull requests
- enforcing lint, type, and security checks
- blocking releases when validation fails
Where the intuition breaks
What this view leaves out
- A green pipeline only covers encoded checks and configured environments; it cannot prove the absence of untested defects.
