name: test-plan description: Generates a comprehensive testing plan based on the current branch changes or a specific PR. Use when creating QA checklists, test plans, or verifying PR readiness.

Generate Testing Plan for PR

Generate a comprehensive testing plan based on the current branch changes or a specific PR.

Arguments

$ARGUMENTS can be:

• Empty: Uses current branch diff against production
• PR number: 2732 - fetches that PR's diff

Steps

1. Get the diff:

   • If $ARGUMENTS is empty: git diff production...HEAD
   • If $ARGUMENTS is a PR number: gh pr diff {PR_NUMBER}

2. Read docs/COMMON_MISTAKES.md for patterns that have caused production bugs

3. Analyze the changes:

   • Identify files changed and their types (components, hooks, utils, styles, pages)
   • Categorize the change (new feature, bug fix, refactor, styling)
   • Assess risk level based on scope and what's touched

4. Generate the testing plan using the criteria below and output format

Testing Criteria

Critical Checks

• Security: No hardcoded secrets, input validation, no unsanitized dangerouslySetInnerHTML
• Error Handling: API failures have fallbacks, validate API response shape before accessing
• Rendering Strategy: SSG for static+SEO, ISR for periodic+SEO, SSR for user-specific+SEO, CSR for private/no-SEO
• Correctness: Code matches requirements, UI matches designs, safely revertible

Standard Checks

• TypeScript: No unjustified any, interfaces for objects, enums for categoricals
• React: No unnecessary useEffect, use useSWR cache directly, skeleton loaders, optimistic updates
• i18n/RTL: All text via t(), CSS logical properties only (margin-inline-start not margin-left)
• Performance: Lazy load non-critical components, new packages <10kb gzipped
• A11y: Semantic elements (button/a not div onClick), images have alt, inputs have label

Regression Checks

• Modified components still work as before
• Shared hooks/utils don't break other consumers
• Style changes don't affect other components
• No race conditions, memory leaks, or unhandled promise rejections

Visual Verification

• Themes: Light, dark, sepia
• RTL: Arabic layout mirrors correctly
• Responsive: Mobile, tablet, desktop breakpoints

Output Format

Generate a testing plan with sections proportional to the change. Skip sections that don't apply.

Copy## Testing Plan

### Change Summary

- **Type:** [New Feature | Bug Fix | Refactor | Styling | Config]
- **Risk Level:** [Low | Medium | High]
- **Files Changed:** X files
- **What it does:** Brief description

---

### Critical Path Tests

<!-- Primary functionality that MUST work -->

- [ ] [Specific test based on what the PR does]
- [ ] [Another specific test]

### State Verification

<!-- Only include states relevant to the change -->

- [ ] Loading state displays correctly
- [ ] Error state displays correctly (simulate: disconnect network / return 500)
- [ ] Empty state displays correctly (no data scenario)
- [ ] Success state displays correctly

### Visual & Theme Tests

<!-- Only if UI changes -->

| Theme | Verified |
| ----- | -------- |
| Light |          |
| Dark  |          |
| Sepia |          |

| Breakpoint      | Verified |
| --------------- | -------- |
| Mobile (<768px) |          |
| Tablet          |          |
| Desktop         |          |

| Direction | Verified |
| --------- | -------- |
| LTR       |          |
| RTL (AR)  |          |

### Regression Tests

<!-- Based on what files were modified, what else might break -->

- [ ] [Component X that imports this file still works]
- [ ] [Feature Y that uses this hook still works]

### Edge Cases

<!-- Specific to this change type -->

- [ ] [Relevant edge case 1]
- [ ] [Relevant edge case 2]

### Accessibility

<!-- Only if interactive elements changed -->

- [ ] Keyboard navigation (Tab, Enter, Escape)
- [ ] Focus states visible
- [ ] Screen reader compatible

---

### Pre-Merge Checks

- [ ] `yarn lint` passes
- [ ] `yarn test` passes
- [ ] `yarn build` succeeds
- [ ] No console.log statements
- [ ] No hardcoded strings (using `t()`)

Guidelines

Be Specific, Not Generic

Copy// Bad - too generic

- [ ] Component works correctly

// Good - specific and actionable

- [ ] Clicking "Add Bookmark" shows success toast and updates bookmark icon
- [ ] Removing bookmark while offline shows error message

Scale to Change Size

Derive from Common Mistakes

Apply patterns from docs/COMMON_MISTAKES.md:

• Fetches data → verify loading/error/empty states
• Uses arrays → verify empty, single item, many items
• User input → verify validation, empty submit, error handling
• Touches styles → verify RTL, themes, responsive
• Modifies shared code → verify all consumers still work

Final Output

After generating the plan:

1. Display the testing plan in markdown format
2. Tell the user they can copy/paste it into their PR description
3. Offer to help test any specific scenarios they're unsure about
