## Testing Workflows

### Complete Registration Flow

1. **Register new user:**
   ```bash
   http POST localhost:5000/api/v1/auth/register \
     email="newuser@example.com" \
     password="SecurePass123!" \
     name="New User"
   ```

2. **Check email for verification link**
   - Look for email from Appwrite
   - Extract `userId` and `secret` from verification URL

3. **Verify email:**
   ```bash
   http GET "localhost:5000/api/v1/auth/verify-email?userId=XXX&secret=YYY"
   ```

4. **Login:**
   ```bash
   http --session=newuser POST localhost:5000/api/v1/auth/login \
     email="newuser@example.com" \
     password="SecurePass123!" \
     remember_me:=false
   ```

5. **Verify session is active:**
   - Session cookie should be set
   - Can now access protected routes

---

### Complete Password Reset Flow

1. **Request password reset:**
   ```bash
   http POST localhost:5000/api/v1/auth/forgot-password \
     email="hero@example.com"
   ```

2. **Check email for reset link**
   - Look for email from Appwrite
   - Extract `userId` and `secret` from reset URL

3. **Reset password:**
   ```bash
   http POST localhost:5000/api/v1/auth/reset-password \
     user_id="XXX" \
     secret="YYY" \
     password="NewSecurePass123!"
   ```

4. **Login with new password:**
   ```bash
   http --session=user1 POST localhost:5000/api/v1/auth/login \
     email="hero@example.com" \
     password="NewSecurePass123!" \
     remember_me:=false
   ```

---

### Testing Protected Routes

Protected routes require authentication. Test with and without session cookies.

**Without authentication:**

```bash
# Should return 401 Unauthorized
http POST localhost:5000/api/v1/auth/logout
```

**With authentication:**

```bash
# Login first
http --session=user1 POST localhost:5000/api/v1/auth/login \
  email="hero@example.com" \
  password="SecurePass123!"

# Now can access protected route
http --session=user1 POST localhost:5000/api/v1/auth/logout
```

## Common Errors

### 400 Bad Request - Validation Error

**Cause:** Invalid input data (email format, weak password, etc.)

**Example:**

```json
{
  "status": 400,
  "error": {
    "code": "VALIDATION_ERROR",
    "message": "Invalid input data",
    "details": {
      "email": "Invalid email format",
      "password": "Password must be at least 8 characters long"
    }
  }
}
```

**Fix:** Check input validation requirements in error details.

---

### 401 Unauthorized

**Cause:** Not authenticated or invalid session.

**Example:**

```json
{
  "status": 401,
  "error": {
    "code": "UNAUTHORIZED",
    "message": "Authentication required. Please log in."
  }
}
```

**Fix:** Login first and include session cookie with requests.

---

### 409 Conflict - User Already Exists

**Cause:** Email already registered.

**Example:**

```json
{
  "status": 400,
  "error": {
    "code": "VALIDATION_ERROR",
    "message": "Invalid input data",
    "details": {
      "email": "An account with this email already exists"
    }
  }
}
```

**Fix:** Use a different email or login instead.

---

### 500 Internal Server Error

**Cause:** Server error (Appwrite connection, configuration issue, etc.)

**Example:**

```json
{
  "status": 500,
  "error": {
    "code": "INTERNAL_ERROR",
    "message": "An internal error occurred. Please try again later."
  }
}
```

**Fix:** Check server logs, verify Appwrite credentials, check network connectivity.

## Testing Tips

### Using httpie Sessions

httpie sessions persist cookies automatically:

```bash
# Login (saves cookies)
http --session=user1 POST localhost:5000/api/v1/auth/login \
  email="hero@example.com" \
  password="SecurePass123!"

# Subsequent requests automatically include cookies
http --session=user1 POST localhost:5000/api/v1/auth/logout
```

### Using curl Cookie Jar

```bash
# Login (save cookies)
curl -X POST http://localhost:5000/api/v1/auth/login \
  -H "Content-Type: application/json" \
  -c cookies.txt \
  -d '{"email": "hero@example.com", "password": "SecurePass123!"}'

# Use cookies in next request
curl -X POST http://localhost:5000/api/v1/auth/logout \
  -b cookies.txt
```

### Pretty Print JSON

```bash
# httpie (automatic)
http POST localhost:5000/api/v1/auth/register ...

# curl (with jq)
curl ... | jq .
```

### Verbose Output

```bash
# httpie
http -v POST localhost:5000/api/v1/auth/login ...

# curl
curl -v -X POST http://localhost:5000/api/v1/auth/login ...
```

## Complete Testing Workflow with Game Mechanics

Here's an end-to-end workflow including skill checks and searches:

### 1. Setup (One-time)

```bash
# Register a new user
http POST localhost:5000/api/v1/auth/register \
  email="adventurer@example.com" \
  password="SecurePass123!" \
  name="Brave Adventurer"

# Login and save session
http --session=adventurer POST localhost:5000/api/v1/auth/login \
  email="adventurer@example.com" \
  password="SecurePass123!" \
  remember_me:=false
```

### 2. Create Character

```bash
# Create a character
http --session=adventurer POST localhost:5000/api/v1/characters \
  name="Elara Moonwhisper" \
  class_id="arcanist" \
  origin_id="memory_thief"

# Save the character_id from the response
```

### 3. Get Available Skills and Difficulties

```bash
# Get available skills (before performing checks)
http GET localhost:5000/api/v1/game/skills

# Get difficulty levels
http GET localhost:5000/api/v1/game/difficulties
```

### 4. Perform Skill Checks

```bash
# Attempt persuasion check (charisma-based)
http --session=adventurer POST localhost:5000/api/v1/game/check \
  character_id="<your_character_id>" \
  check_type="skill" \
  skill="persuasion" \
  difficulty="hard" \
  bonus:=1 \
  context:='{"npc_name": "Merchant"}'

# Attempt stealth check (dexterity-based)
http --session=adventurer POST localhost:5000/api/v1/game/check \
  character_id="<your_character_id>" \
  check_type="skill" \
  skill="stealth" \
  dc:=20 \
  bonus:=0

# Attempt arcana check (intelligence-based)
http --session=adventurer POST localhost:5000/api/v1/game/check \
  character_id="<your_character_id>" \
  check_type="skill" \
  skill="arcana" \
  difficulty="medium" \
  bonus:=2
```

### 5. Perform Searches

```bash
# Search in a forest
http --session=adventurer POST localhost:5000/api/v1/game/check \
  character_id="<your_character_id>" \
  check_type="search" \
  location_type="forest" \
  difficulty="easy" \
  bonus:=0

# Search in a cave
http --session=adventurer POST localhost:5000/api/v1/game/check \
  character_id="<your_character_id>" \
  check_type="search" \
  location_type="cave" \
  dc:=13 \
  bonus:=1

# Search in a town
http --session=adventurer POST localhost:5000/api/v1/game/check \
  character_id="<your_character_id>" \
  check_type="search" \
  location_type="town" \
  difficulty="hard" \
  bonus:=2
```
