QA Testing

QA Testing

Design test plans and cases that cover happy paths, edge cases, and regressions.

Workflow

1. Identify risk areas and critical paths.
2. Build a test matrix with coverage categories.
3. Define expected outcomes and data.
4. Ensure negative/security-path tests are included for config and boundary conditions.
5. Report results and gaps.

Root-Cause Verification Matrix (QA Owner)

Consume the causality statement from debugging-assistant and verify the proposed fix closes the real defect.

QA Responsibilities

1. Build a verification matrix mapping each original failure to:
   • root cause
   • fix location
   • regression test(s)
   • edge-case test(s)
2. Require at least one regression test that fails before and passes after.
3. Run layered verification:
   • targeted check first
   • full lint and test suite after targeted checks pass
4. Report coverage gaps and residual risk for code-review.

Ambiguity Handling

If expected behavior is unclear during test design, mark it as blocking and first apply the Spec-Clarity Gate (canonical definition in .github/copilot-instructions.md). Route to human verification only if ambiguity remains (do not infer by convenience).

Reference: debugging-assistant -> Human Verification Escalation (Blocking).

CORS + Sync Regression Cases (when relevant)

Include targeted tests for:

• Allowed origin preflight success (OPTIONS) with expected allow-origin header.
• Disallowed origin preflight behavior (no allow-origin).
• Normal JSON/error responses carrying consistent CORS headers.
• Config parsing edge cases (comma-separated allowlist with spaces/empty values).
• Backward compatibility for sync payload migrations (v1 read + v2 write/normalize).

Refactor Test Focus (Repo)

• High-priority before refactors: UI overlay DOM structure, focus trap/keyboard flow, sync error categorization, retry/backoff logic, performance baselines, worker crypto/validation utilities.
• Verification depth: cross-browser smoke checks plus financial accuracy spot checks for any UI/behavior change.
• CI gating: run targeted tests first, then full suite once targeted checks are green.

Output Format

• Test plan
• Coverage gaps
• Recommendations
