## ✅ Phase 1: Test Strategy and Approach

### 🎯 **Main Goal**

Ensure that all components of the loyalty system (tiers, rewards, referrals, points, redemptions, and settings) work **individually** and **as a system** under common use cases and edge cases.

## ✅ Phase 2: Testing Layers & Approach

| Layer                 | Description                                                           | Type               |
| --------------------- | --------------------------------------------------------------------- | ------------------ |
| **Unit tests**        | Test isolated model logic and traits (no DB involved, mock if needed) | `phpunit`          |
| **Feature tests**     | Test HTTP routes, controllers, middleware, views, DB states, etc.     | `php artisan test` |
| **Integration tests** | Test cross-module workflows: referrals + rewards + redemption         | `php artisan test` |

> All tests go under: `tests/Feature/Loyalty` and `tests/Unit/Loyalty`

## ✅ Phase 3: Key Scenarios to Test

### 🔹 Tiers

* Assign correct tier based on point boundaries
* Upgrade tier when points increase
* Edge: user between two tiers, or exceeds max

### 🔹 Rewards

* Can list and view rewards
* Cannot redeem if not enough points
* Successful reward redemption subtracts points

### 🔹 Referrals

* User can refer another
* Referral gives bonus to referrer and/or referee
* Cannot refer self or duplicate referral

### 🔹 Loyalty Points

* User can earn points from multiple sources
* Total balance reflects earned - redeemed
* History log is accurate and ordered

### 🔹 Settings

* Admin can toggle settings like "referral\_bonus"
* Settings update is respected during point award

### 🔹 UI/Access

* Only admins can access admin panel
* Authenticated users see their loyalty data
* Unauthorized access returns 403 or redirects

## ✅ Phase 5: Test List Summary

| Test File                     | Key Assertions                                                 |
