A Pragmatic Testing Strategy: From Manual Smoke to CI Guards
Testing isn't about reaching a percentage of coverage. It's about putting a safety net under the changes that matter, in the order that pays.

Testing strategies fail in two directions: teams that test everything slowly and teams that test nothing confidently. The pragmatic middle treats tests as an investment portfolio — you spend coverage where the risk is, and you let the return decide the next investment.
The testing pyramid, prioritized
- Critical path tests: checkout, login, payments, core workflows
- Business logic tests: pricing rules, calculations, validations
- Regression guards: the bugs you've actually shipped, pinned forever
- Happy-path UI smoke: the app boots and the key flows render
The ROI rule
Every test has a cost: writing time, maintenance, and CI minutes. The tests that pay for themselves are the ones that catch real regressions — which is why the best first suite is built from your bug history, not from a coverage target.
The practical minimum
If you can only afford three things: tests on every payment and auth path, a smoke test on every deploy, and a CI gate that runs both before merge. That's not a complete strategy — it's the foundation that makes every other test investment meaningful.
Coverage percentages tell you what code the tests visit. Bug history tells you where they need to live.
