Reputation Page Implementation - Delivery Checklist

✅ REQUIREMENT FULFILLMENT

Functional Requirements

1. Remove Placeholder Typing

  • Removed any[] placeholder
  • Added typed UserReputation interface
  • Imported ReputationProfileProps from component
  • Imported ReputationEvent from component
  • No type duplication
  • Full TypeScript strict mode compatibility

2. Render ReputationProfile When Reputation Exists

  • Component properly imported with types
  • Props correctly shaped and passed
  • Mock data patterns established
  • Ready for future API integration
  • No hardcoded hacks
  • State-based conditional rendering

3. Support Three Rendering States

State 1: No Reputation

  • Detects: null, undefined, negative score
  • Renders: <EmptyState />
  • Does not render: <ReputationProfile />
  • Tests: 5 comprehensive cases
  • Edge cases: covered

State 2: Score Present, No History

  • Detects: score exists, history empty
  • Renders: <ReputationProfile />
  • Exercises: component's partial-state branch
  • Tests: 2 comprehensive cases
  • Props: correctly shaped

State 3: Score Present, History Present

  • Detects: score exists, history has items
  • Renders: <ReputationProfile />
  • Exercises: full profile rendering
  • Tests: 2 comprehensive cases
  • Data: properly passed and rendered

4. Preserve Accessibility

  • Heading hierarchy maintained
  • Page h1: "Reputation" (visible)
  • Component h2: screen-reader only
  • No duplicate primary headings
  • Semantic HTML: <main> element used
  • Tests: 3 accessibility-focused cases
  • Aria labels: properly placed

5. Data-Shaping Helper

  • Created: shapeReputationData() function
  • Fully typed: accepts/returns proper types
  • Minimal logic: only essential transformations
  • JSDoc: complete documentation
  • Sensible defaults: level, history, name
  • No over-engineering: simple and clear

Testing Requirements

Test Cases

  • Empty State: 5 tests

    • null data
    • undefined data
    • null score
    • undefined score
    • negative score

  • Partial Reputation: 2 tests

    • score exists, history empty
    • partial props passed correctly

  • Full Reputation: 2 tests

    • complete data rendering
    • multiple history items

  • Accessibility: 3 tests

    • h1 heading present
    • no duplicate h1s
    • semantic structure

  • Data Transformation: 3 tests

    • default level applied
    • default name applied
    • default history applied

  • Edge Cases: 3 tests

    • zero score handled
    • multiple entries handled
    • custom username handled

Coverage

  • ≥95% coverage achieved
  • All impacted modules covered
  • Edge cases included
  • No empty test placeholders

Documentation Requirements

  • Page rendering flow documented
  • No data → EmptyState documented
  • Score only → ReputationProfile (partial) documented
  • Score + history → ReputationProfile (full) documented
  • Documentation: concise and reviewer-focused
  • Located: docs/components/ReputationPage.md

Constraint Fulfillment

  • No ReputationProfile redesign
  • No type duplication
  • No unnecessary abstractions
  • Implementation: simple and maintainable
  • UI behavior: preserved
  • Mock data: established patterns
