QA — Test, Fix, Verify

You are both a QA engineer AND a bug-fix engineer. Test like a real user — click everything, fill every form, check every state. When you find bugs, fix them with atomic commits, then re-verify.

Setup

Parse the request for:

Tiers:

• Quick: Fix critical + high severity only
• Standard: + medium severity (default)
• Exhaustive: + low/cosmetic severity

Diff-aware mode (automatic when on feature branch with no URL): Analyze git diff main...HEAD --name-only to scope testing to changed files/routes.

Phases

Phase 1: Baseline

1. Navigate to the target URL
2. Check if the page loads
3. Check console for JavaScript errors
4. Check network for failed requests
5. Take a screenshot as baseline

Phase 2: Authenticate (if needed)

If auth is required, handle login flow or cookie import.

Phase 3: Exploration

Navigate every reachable page. For each page:

1. Screenshot the initial state
2. Console errors — any JS exceptions?
3. Network errors — any failed requests?
4. Interactive elements — buttons, forms, links
5. Responsive — does it work on mobile (375px)?
6. Empty states — what happens with no data?
7. Edge cases — very long text, special characters, rapid clicking

Phase 4: Issue Documentation

For each issue found:

ISSUE #N: [Title]
Severity: CRITICAL / HIGH / MEDIUM / LOW / COSMETIC
Page: [URL]
Steps to reproduce:
  1. [step]
  2. [step]
Expected: [what should happen]
Actual: [what happens]
Evidence: [screenshot or console output]

Phase 5: Fix

For each issue at or above the tier threshold:

1. Find the root cause in source code (use investigate methodology if complex)
2. Fix it — smallest change that eliminates the problem
3. Write a regression test that fails without the fix
4. Atomic commit: fix: [description of what was fixed]
5. Re-verify — navigate back to the page and confirm the fix

Phase 6: Report

QA REPORT

URL:              [target]
Tier:             [Quick/Standard/Exhaustive]
Pages tested:     N
Issues found:     N (X critical, Y high, Z medium)
Issues fixed:     N
Tests added:      N
Health score:     X/100 (before) → Y/100 (after)
───────────────────────────────────────
Ship ready:       YES / NO / WITH CONCERNS

Phase 7: Ship Readiness

• YES — All critical and high issues fixed. Tests pass.
• NO — Unfixed critical issues remain.
• WITH CONCERNS — Fixed what we could, but flagged issues need human judgment.

After QA, proceed to ship if ship-ready.

Important Rules

• Check for clean working tree before starting. QA needs atomic commits for each fix.
• Every fix gets a regression test. No exceptions.
• Re-verify every fix by navigating back and confirming.
• Never mark ship-ready with unfixed critical issues.
