🔧 2. Implementation Details

Template Structure:

<div v-if="!loading && !error" class="row q-gutter-md q-mb-xl">  <div class="col-12 col-sm-6 col-lg-3"> <q-card class="shadow-1 stats-card"> <q-card-section class="text-center"> <q-icon name="directions_car" color="primary" size="32px" /> <div class="text-h4 text-weight-bold text-primary">{{ totalVehicles }}</div> <div class="text-body2 text-grey-7">Total Kendaraan</div> </q-card-section> </q-card> </div>  </div>

Computed Properties:

// Total kendaraan const totalVehicles = computed(() => { return vehicles.value.length }) // Mesin hidup const engineOnCount = computed(() => { return vehicles.value.filter(vehicle => vehicle.StatusMesin === 'Hidup').length }) // Mesin mati const engineOffCount = computed(() => { return vehicles.value.filter(vehicle => vehicle.StatusMesin === 'Mati').length }) // Overspeed >50 km/h const overspeedCount = computed(() => { return vehicles.value.filter(vehicle => { const speed = parseFloat(vehicle.Kecepatan) || 0 return speed > 50 }).length })

🧪 3. Test Scenarios

Scenario 1: Sample Data Calculation

Misalkan ada 10 kendaraan dengan data berikut:

Vehicle	StatusMesin	Kecepatan	Contributes To
Vehicle 1	Hidup	45 km/h	Total, Mesin Hidup
Vehicle 2	Hidup	65 km/h	Total, Mesin Hidup, Overspeed
Vehicle 3	Mati	0 km/h	Total, Mesin Mati
Vehicle 4	Hidup	80 km/h	Total, Mesin Hidup, Overspeed
Vehicle 5	Mati	0 km/h	Total, Mesin Mati

Expected Results:

10
Total Kendaraan

3
Mesin Hidup

2
Mesin Mati

2
Overspeed >50 km/h

Scenario 2: Edge Cases

Case	Data	Expected Result	Status
No Vehicles	vehicles = []	All counts = 0	☐ To Test
All Engines Off	All StatusMesin = 'Mati'	engineOnCount = 0	☐ To Test
All Engines On	All StatusMesin = 'Hidup'	engineOffCount = 0	☐ To Test
No Overspeed	All Kecepatan ≤ 50	overspeedCount = 0	☐ To Test
All Overspeed	All Kecepatan > 50	overspeedCount = totalVehicles	☐ To Test

🎨 4. Visual Design

Card Layout:

Grid: row with col-12 col-sm-6 col-lg-3 (responsive)
Spacing: q-gutter-md between cards
Margin: q-mb-xl below statistics section
Style: shadow-1 stats-card with hover effects

Card Content:

Icon: 32px size with color matching theme
Number: text-h4 text-weight-bold with theme color
Label: text-body2 text-grey-7
Alignment: text-center

Color Scheme:

Card	Color	Hex Code	Usage
Total Kendaraan	Primary	#1976d2	General information
Mesin Hidup	Positive	#4caf50	Good status (engines on)
Mesin Mati	Negative	#f44336	Alert status (engines off)
Overspeed	Warning	#ff9800	Warning status (speed violation)

Step 1: Akses Customer Asset Page

Login: Login Page
Credentials: dayansgi / dayansgi123
Navigate: Customer Asset Page

Step 2: Verifikasi Statistics Cards

What to Check	How to Check	Expected Result
Cards Position	Look at top of page above vehicle cards	4 cards in a row (responsive layout)
Total Kendaraan	Count vehicle cards below	Number matches actual vehicle count
Mesin Hidup	Count green status chips	Number matches "Hidup" status count
Mesin Mati	Count red status chips	Number matches "Mati" status count
Overspeed	Count vehicles with speed >50 km/h	Number matches high speed vehicles

Step 3: Responsive Testing

Desktop (≥1024px): 4 cards in one row
Tablet (768-1023px): 2 cards per row
Mobile (<768px): 1 card per row

Step 4: Data Accuracy

Manually count vehicles and verify totals
Check engine status distribution
Verify overspeed calculation (>50 km/h)
Ensure real-time updates when data changes

🔧 6. Technical Implementation

Vue.js Computed Properties:

// Reactive calculations that update automatically const totalVehicles = computed(() => vehicles.value.length) const engineOnCount = computed(() => vehicles.value.filter(v => v.StatusMesin === 'Hidup').length ) const engineOffCount = computed(() => vehicles.value.filter(v => v.StatusMesin === 'Mati').length ) const overspeedCount = computed(() => vehicles.value.filter(v => parseFloat(v.Kecepatan) > 50).length )

Responsive Grid System:

Performance Considerations:

Computed Properties: Cached and only recalculate when dependencies change
Filter Operations: Efficient array filtering for statistics
Type Safety: parseFloat() with fallback for speed calculations
Conditional Rendering: Only show when data is loaded
