## Context
|
|
|
|
The codebase has grown across frontend UX, backend ingestion, translations, analytics, and admin tooling. Quality checks are currently ad hoc and mostly manual, creating regression risk. A single cross-layer test and observability program is needed to enforce predictable release quality.
|
|
|
|
## Goals / Non-Goals
|
|
|
|
**Goals:**
|
|
- Establish CI quality gates covering unit, integration, E2E, accessibility, security, and performance.
|
|
- Provide deterministic test fixtures for UI/API/DB workflows.
|
|
- Define explicit coverage targets for critical paths and edge cases.
|
|
- Add production monitoring and alerting for latency, failures, and freshness.
|
|
|
|
**Non-Goals:**
|
|
- Migrating the app to a different framework.
|
|
- Building a full SRE platform from scratch.
|
|
- Replacing existing business logic outside remediation findings.
|
|
|
|
## Decisions
|
|
|
|
### Decision 1: Layered test pyramid with release gates
|
|
Adopt unit + integration + E2E layering; block release when any gate fails.
|
|
|
|
### Decision 2: Deterministic test data contracts
|
|
Use seeded fixtures and mockable provider boundaries for repeatable results.
|
|
|
|
### Decision 3: Accessibility and speed as first-class CI checks
|
|
Treat WCAG and page-speed regressions as gate failures with explicit thresholds.
|
|
|
|
### Decision 4: Security checks split by class
|
|
Run dependency audit, static security lint, and API abuse smoke tests separately for clearer ownership.
|
|
|
|
### Decision 5: Monitoring linked to user-impacting SLOs
|
|
Alert on API error rate, response latency, scheduler freshness, and failed fetch cycles.
|
|
|
|
## Risks / Trade-offs
|
|
|
|
- **[Risk] Longer CI times** -> Mitigation: split fast/slow suites, parallelize jobs.
|
|
- **[Risk] Flaky E2E tests** -> Mitigation: stable fixtures, retry policy only for known transient failures.
|
|
- **[Risk] Alert fatigue** -> Mitigation: tune thresholds with burn-in period and severity levels.
|
|
|
|
## Migration Plan
|
|
|
|
1. Baseline current test/tooling and add missing framework dependencies.
|
|
2. Implement layered suites and CI workflow stages.
|
|
3. Add WCAG, speed, and security checks with thresholds.
|
|
4. Add monitoring dashboards and alert routes.
|
|
5. Run remediation sprint for failing gates.
|
|
|
|
Rollback:
|
|
- Keep non-blocking mode for new gates until stability criteria are met.
|
|
|
|
## Open Questions
|
|
|
|
- Which minimum coverage threshold should be required for merge (line/branch)?
|
|
- Which environments should execute full E2E and speed checks (PR vs nightly)?
