Regression prevention and quality gates
Problem
The platform integration surfaces — Stripe webhook handling, GCP deployment pipeline, warehouse connectivity, and Fivetran platform handoff — lack automated regression gates. Changes to billing logic, infrastructure config, or connectivity code can ship without integration tests catching regressions. This means a deploy that fixes one billing edge case can silently break subscription state sync, or a Cloud Run config change can break secret injection, and the team only discovers it from user reports. Automated quality gates must enforce that known-good behavior is preserved across releases.
Context
- Manual review is not enough to protect deployment, billing, connectivity, and production launch integration once the change rate increases; regressions will keep shipping unless the highest-value checks become automatic.
- This task should identify what needs gating in CI or structured review and what evidence is sufficient to block a risky change before it reaches users.
- Expected touchpoints include deployment automation, environment/runbook docs, billing/integration code, and ops checks, automated tests, eval/QA checks, and any release or review scripts that can enforce the new gates.
Possible Solutions
- A - Add only a few narrow tests around current bugs: easy to land, but it rarely protects the broader behavior contract.
- B - Recommended: define a regression-gate bundle around the core behavior contract: combine focused tests, snapshots/evals, and required review evidence for risky changes.
- C - Depend on manual smoke testing before each release: better than nothing, but too inconsistent to serve as a durable gate.
Plan
- Identify the highest-risk behavior contracts for deployment, billing, connectivity, and production launch integration and the types of changes that should be blocked when they regress.
- Choose the smallest practical set of automated checks and required review evidence that covers those contracts well enough to matter.
- Wire the new gates into the relevant test, review, or release surfaces and document when exceptions are allowed.
- Trial the gates on a few representative changes and tighten the signal-to-noise ratio before expanding the coverage further.
