Component Implementation

<!-- resources/views/components/card.blade.php -->
@props([
    'variant' => 'default',
    'hover' => false,
    'highlight' => false
])

<div {{ $attributes->merge([
    'class' => collect([
        'bg-cream rounded-lg p-6',
        'shadow-sm' => $variant === 'default',
        'shadow-md' => $variant === 'elevated',
        'hover:shadow-md hover:-translate-y-0.5 transition-all cursor-pointer' => $hover,
        'border-s-4 border-gold' => $highlight,
    ])->filter()->implode(' ')
]) }}>
    {{ $slot }}
</div>

<!-- Stat card component -->
@props(['icon', 'value', 'label', 'trend' => null])

<x-card>
    <div class="flex items-center gap-4">
        <div class="p-3 bg-gold/10 rounded-lg">
            <flux:icon :name="$icon" class="w-6 h-6 text-gold" />
        </div>
        <div>
            <div class="text-2xl font-bold text-navy">{{ $value }}</div>
            <div class="text-sm text-charcoal/70">{{ $label }}</div>
            @if($trend)
                <div class="text-xs {{ $trend > 0 ? 'text-success' : 'text-danger' }}">
                    {{ $trend > 0 ? '+' : '' }}{{ $trend }}%
                </div>
            @endif
        </div>
    </div>
</x-card>

Edge Cases

  • Null/Zero Trend: Stat card should gracefully handle null trend (hidden) and 0 trend (show as neutral)
  • RTL Layout: Cards with border-s-4 will automatically flip border to right side in RTL mode
  • Container Overflow: Content exceeding max-width should be contained; consider horizontal scroll for tables
  • Missing Icon: Handle gracefully if Flux icon name doesn't exist (fallback or hide icon container)
  • Empty Cards: Ensure cards maintain minimum height even with minimal content

Testing Requirements

Unit Tests

  • Card component renders with default variant
  • Card component renders with elevated variant
  • Card component applies hover classes when hover=true
  • Card component applies highlight border when highlight=true
  • Stat card displays value and label correctly
  • Stat card shows positive trend with + prefix and success color
  • Stat card shows negative trend with danger color
  • Stat card hides trend indicator when trend=null

Visual/Browser Tests

  • Hover lift effect animates smoothly
  • Shadow transitions on hover
  • Cards display correctly in RTL layout
  • Container centers content and respects max-width
  • Responsive behavior at all breakpoints

Test File Location

tests/Feature/Components/CardComponentTest.php

Definition of Done

  • Card component created
  • Shadow and radius consistent
  • Hover effects work
  • Stat cards work
  • Highlight variant works
  • Container max-width applied
  • Tests pass

Agent Model Used

Claude Opus 4.5 (claude-opus-4-5-20251101)

Completion Notes

  • Created resources/views/components/ui/card.blade.php with variants (default/elevated), hover effects, and highlight border
  • Created resources/views/components/ui/stat-card.blade.php with icon, value, label, and trend indicator support
  • Added CSS classes in resources/css/app.css: .container-max, .shadow-card, .shadow-card-hover
  • Card component uses custom shadow (0 2px 8px rgba(0,0,0,0.1)) per specs
  • Stat card handles null trend (hidden), zero trend (neutral color), positive trend (+prefix, success), negative trend (danger)
  • Icon container conditionally renders only when icon prop is provided
  • RTL support via border-s-4 (logical property flips automatically)
  • All 17 component tests pass

Conditional icon container rendering Handle missing icon gracefully per edge cases
border-s-4 for highlight Logical property for automatic RTL support

QA Results

Review Date: 2026-01-03

Reviewed By: Quinn (Test Architect)

Risk Assessment

  • Risk Level: LOW
  • Justification:
    • UI-only story (no auth/payment/security concerns)
    • < 500 lines changed
    • Story has 6 acceptance criteria (moderate complexity)
    • No previous gate failures
    • Tests included

Code Quality Assessment

Overall: Excellent implementation that fully meets specifications.

The implementation demonstrates strong adherence to project standards:

  1. Card component (card.blade.php:1-30) - Clean, well-structured Blade component using @props correctly
  2. Stat card (stat-card.blade.php:1-34) - Proper composition pattern using <x-ui.card> wrapper
  3. CSS classes (app.css:414-428) - Custom shadow values match exact spec requirements

Strengths:

  • Match expression used effectively in both components for clean conditional logic
  • Proper use of logical CSS property (border-s-4) for automatic RTL support
  • Edge cases handled: null trend hidden, zero trend neutral, missing icon gracefully handled
  • Custom CSS classes keep exact shadow values from spec (0 2px 8px rgba(0,0,0,0.1))

Code patterns followed correctly:

  • Flux UI integration pattern maintained
  • Blade component conventions followed
  • CSS layer organization consistent with existing codebase

Refactoring Performed

None required - code quality is excellent.

AC# Acceptance Criteria Test Coverage Status
1 Card Styling (bg, shadow, radius, padding) card component renders with default variant
2 Gold Border Highlight card component applies highlight border when highlight is true
3 Hover States (lift, shadow) card component applies hover classes when hover is true
4 Dashboard Stat Cards (icon, value, trend) stat card displays all elements together + trend tests

6 Containers (max-width 1200px, centered) .container-max CSS class added

Test Architecture Assessment

Test count: 17 tests, 76 assertions Coverage assessment: Comprehensive

Given-When-Then mapping:

  • Given default card → When rendered → Then has bg-cream, rounded-lg, p-6, shadow-card ✓
  • Given elevated variant → When rendered → Then has shadow-md instead of shadow-card ✓
  • Given hover=true → When rendered → Then has hover classes + cursor-pointer ✓
  • Given highlight=true → When rendered → Then has border-s-4 border-gold ✓
  • Given stat card with positive trend → When rendered → Then shows +prefix, text-success ✓
  • Given stat card with negative trend → When rendered → Then shows text-danger ✓
  • Given stat card with null trend → When rendered → Then hides trend indicator ✓
  • Given stat card with zero trend → When rendered → Then shows neutral color ✓
  • Given stat card without icon → When rendered → Then hides icon container ✓

Edge cases covered:

  • ✓ Null trend handling
  • ✓ Zero trend (neutral color)
  • ✓ Missing icon gracefully handled
  • ✓ Multiple props combined

Gaps identified: None

Improvements Checklist

  • All acceptance criteria implemented
  • All edge cases from story handled
