+
+## Giới thiệu
+Tài liệu này mô tả các test case đã được triển khai trong dự án, giúp đảm bảo chất lượng và độ tin cậy của mã nguồn.
+
+## Cấu trúc thư mục test
+```
+internal/
+  transport/
+    http/
+      middleware/
+        auth_test.go        # Test xác thực và phân quyền
+        middleware_test.go   # Test CORS và rate limiting
+      handler/
+        health_handler_test.go  # Test health check endpoints
+  service/
+    auth_service_test.go      # Test service xác thực
+```
+
+## Các loại test case
+
+### Auth Middleware
+
+#### Xác thực người dùng
+1. **TestNewAuthMiddleware**
+   - Mục đích: Kiểm tra khởi tạo AuthMiddleware
+   - Input: AuthService
+   - Expected: Trả về instance AuthMiddleware
+
+2. **TestAuthenticate_Success**
+   - Mục đích: Xác thực thành công với token hợp lệ
+   - Input: Header Authorization với token hợp lệ
+   - Expected: Trả về status 200 và lưu thông tin user vào context
+
+3. **TestAuthenticate_NoAuthHeader**
+   - Mục đích: Không có header Authorization
+   - Input: Request không có header Authorization
+   - Expected: Trả về lỗi 401 Unauthorized
+
+4. **TestAuthenticate_InvalidTokenFormat**
+   - Mục đích: Kiểm tra định dạng token không hợp lệ
+   - Input:
+     - Token không có "Bearer" prefix
+     - Token rỗng sau "Bearer"
+   - Expected: Trả về lỗi 401 Unauthorized
+
+5. **TestAuthenticate_InvalidToken**
+   - Mục đích: Token không hợp lệ hoặc hết hạn
+   - Input: Token không hợp lệ
+   - Expected: Trả về lỗi 401 Unauthorized
+
+#### Phân quyền (RBAC)
+1. **TestRequireRole_Success**
+   - Mục đích: Người dùng có role yêu cầu
+   - Input: User có role phù hợp
+   - Expected: Cho phép truy cập
+
+2. **TestRequireRole_Unauthenticated**
+   - Mục đích: Chưa xác thực
+   - Input: Không có thông tin xác thực
+   - Expected: Trả về lỗi 401 Unauthorized
+
+3. **TestRequireRole_Forbidden**
+   - Mục đích: Không có quyền truy cập
+   - Input: User không có role yêu cầu
+   - Expected: Trả về lỗi 403 Forbidden
+
+#### Helper Functions
+1. **TestGetUserFromContext**
+   - Mục đích: Lấy thông tin user từ context
+   - Input: Context có chứa user
+   - Expected: Trả về thông tin user
+
+2. **TestGetUserFromContext_NotFound**
+   - Mục đích: Không tìm thấy user trong context
+   - Input: Context không có user
+   - Expected: Trả về lỗi
+
+3. **TestGetUserIDFromContext**
+   - Mục đích: Lấy user ID từ context
+   - Input: Context có chứa user
+   - Expected: Trả về user ID
+
+4. **TestGetUserIDFromContext_InvalidType**
+   - Mục đích: Kiểm tra lỗi khi kiểu dữ liệu không hợp lệ
+   - Input: Context có giá trị không phải kiểu *Claims
+   - Expected: Trả về lỗi
+
+### CORS Middleware
+1. **TestDefaultCORSConfig**
+   - Mục đích: Kiểm tra cấu hình CORS mặc định
+   - Expected: Cấu hình mặc định cho phép tất cả origins
+
+2. **TestCORS**
+   - Mục đích: Kiểm tra hành vi CORS
+   - Các trường hợp:
+     - Cho phép tất cả origins
+     - Chỉ cho phép origin cụ thể
+     - Xử lý preflight request
+
+### Rate Limiting
+1. **TestDefaultRateLimiterConfig**
+   - Mục đích: Kiểm tra cấu hình rate limiter mặc định
+   - Expected: Giới hạn mặc định được áp dụng
+
+2. **TestRateLimit**
+   - Mục đích: Kiểm tra hoạt động của rate limiter
+   - Expected: Chặn request khi vượt quá giới hạn
+
+### Security Config
+1. **TestSecurityConfig**
+   - Mục đích: Kiểm tra cấu hình bảo mật
+   - Các trường hợp:
+     - Cấu hình mặc định
+     - Áp dụng cấu hình cho router
+
+## Cách chạy test
+
+### Chạy tất cả test
+```bash
+go test ./...
+```
+
+### Chạy test với coverage
+```bash
+go test -coverprofile=coverage.out ./...
+go tool cover -html=coverage.out
+```
+
+### Chạy test cụ thể
+```bash
+go test -run ^TestName$
+```
+
+## Best Practices
+
+1. **Đặt tên test rõ ràng**
+   - Sử dụng cấu trúc: `Test[FunctionName]_[Scenario]`
+   - Ví dụ: `TestAuthenticate_InvalidToken`
+
+2. **Mỗi test một trường hợp**
+   - Mỗi test function chỉ kiểm tra một trường hợp cụ thể
+   - Sử dụng subtests cho các test case liên quan
+
+3. **Kiểm tra cả trường hợp lỗi**
+   - Kiểm tra cả các trường hợp thành công và thất bại
+   - Đảm bảo có thông báo lỗi rõ ràng
+
+4. **Sử dụng mock cho các phụ thuộc**
+   - Sử dụng thư viện `testify/mock` để tạo mock
+   - Đảm bảo test độc lập với các thành phần bên ngoài
+
+5. **Kiểm tra biên**
+   - Kiểm tra các giá trị biên và trường hợp đặc biệt
+   - Ví dụ: empty string, nil, giá trị âm, v.v.
+
+6. **Giữ test đơn giản**
+   - Test cần dễ hiểu và dễ bảo trì
+   - Tránh logic phức tạp trong test
+
+7. **Đảm bảo test chạy nhanh**
+   - Tránh I/O không cần thiết
+   - Sử dụng `t.Parallel()` cho các test độc lập
