+# Auth Service Tests
+
+## Directory Structure
+
+This directory contains test placeholder files for services in `apps/website/app/auth`.
+
+## Note
+
+There are **no service files** in `apps/website/app/auth`. The directory only contains:
+- Page components (e.g., `login/page.tsx`, `signup/page.tsx`)
+- Layout files (e.g., `layout.tsx`)
+
+## Actual Auth Services
+
+The actual auth services are located in:
+- `apps/website/lib/services/auth/AuthService.ts`
+- `apps/website/lib/services/auth/SessionService.ts`
+- `apps/website/lib/services/auth/AuthPageService.ts`
+
+These services already have test implementations in:
+- `apps/website/lib/services/auth/AuthService.test.ts`
+- `apps/website/lib/services/auth/SessionService.test.ts`
+
+## Test Coverage
+
+The existing tests cover:
+- **Happy paths**: Successful signup, login, logout, and session retrieval
+- **Failure modes**: Error handling when API calls fail
+- **Retries**: Not applicable for these services (no retry logic)
+- **Fallback logic**: Not applicable for these services
+- **Aggregation logic**: Not applicable for these services
+- **Decision branches**: Different outcomes based on API response (success vs failure)
+
+## Future Services
+
+If service files are added to `apps/website/app/auth` in the future, corresponding test placeholder files should be created here following the pattern:
+- Service file: `apps/website/app/auth/services/SomeService.ts`
+- Test file: `apps/website/tests/services/auth/SomeService.test.ts`
