4. Ensure smooth priority transitions
5. Validate performance targets

---

Test Environment Setup

Prerequisites

1. TrinityCore Build: Clean compilation with Phase 2.7 changes

2. Database: Fresh playerbot_* databases with test accounts

3. Configuration: playerbots.conf with appropriate settings:

   Playerbot.Enable = 1
   Playerbot.MaxBots = 100
   Playerbot.AI.UpdateDelay = 100
   Playerbot.Performance.EnableMonitoring = 1
   

4. Test Accounts:

   • Account 1: Player account (no bots)
   • Accounts 2-11: Bot accounts (10 bots each, 100 total)
   • Bots distributed across all 13 classes

Test Bot Setup

-- Create test player account
INSERT INTO playerbot_auth.account (username, sha_pass_hash, email, reg_mail)
VALUES ('testplayer', SHA2('testpass:TESTPLAYER', 256), '[email protected]', '[email protected]');

-- Verify bot accounts exist (accounts 2-11)
SELECT id, username FROM playerbot_auth.account WHERE id BETWEEN 2 AND 11;

-- Verify bot characters
SELECT account, name, class, level FROM playerbot_characters.characters
WHERE account BETWEEN 2 AND 11
ORDER BY account, guid;

In-Game Setup

1. Login as test player (account 1)

2. Spawn test bots:

   .playerbot bot add <botname>  # Add bots to group
   .playerbot bot remove <botname>  # Remove from group
   

3. Enable debug logging (if available):

   .playerbot debug on
   .playerbot debug priority

Test Scenarios

Scenario 1: Solo Bot Idle → Combat Transition

Objective: Verify solo bots correctly transition from Idle to Combat and back.

Test Steps:

1. Spawn solo bot (not in group)
2. Verify bot uses IdleStrategy (wander, stand, etc.)
3. Aggro nearby enemy
4. VERIFY: Bot enters combat state
5. VERIFY: Combat strategy activates (priority 100)
6. VERIFY: Idle strategy deactivates (priority 10)
7. VERIFY: Only Combat strategy executes
8. Kill enemy
9. VERIFY: Bot returns to Idle strategy

Expected Behavior:

Initial State:
- Active: IdleStrategy (priority 10)
- Behavior: Random wandering or standing

Combat Start:
- Active: CombatStrategy (priority 100)
- Idle: Blocked by priority system
- Behavior: Attack enemy with class rotation

Combat End:
- Active: IdleStrategy (priority 10)
- Behavior: Return to wandering

Validation Commands:

// Check active strategy
BehaviorPriorityManager* mgr = botAI->GetPriorityManager();
Strategy* active = mgr->GetActiveStrategy();
// Should be Combat during combat, Idle otherwise

// Check performance
PerformanceMetrics metrics = botAI->GetPerformanceMetrics();
// strategiesEvaluated should be 1 (single strategy execution)

Scenario 2: Group Bot Follow → Combat Transition (Issue #2 Fix)

Objective: Verify grouped bots switch from Follow to Combat when leader engages.

Test Steps:

1. Create group with player leader and 1 melee bot (Warrior/Paladin)
2. VERIFY: Bot uses LeaderFollowBehavior (priority 50)
3. Move as leader, verify bot follows
4. Leader attacks enemy
5. VERIFY: Bot enters combat
6. VERIFY: Follow strategy deactivates (relevance 0.0f)
7. VERIFY: Combat strategy activates (priority 100)
8. VERIFY: Bot acquires leader's target (Task 2.3 fix)
9. VERIFY: Bot attacks enemy
10. Kill enemy
11. VERIFY: Bot returns to Follow strategy

Expected Behavior:

Following State:
- Active: LeaderFollowBehavior (priority 50)
- Behavior: Follow leader at 5yd distance
- Bot facing: Leader

Combat Transition:
- Leader attacks → Bot enters combat
- Follow::CalculateRelevance() returns 0.0f
- Follow::IsActive() returns false
- Priority system filters Follow from active strategies
- Combat::IsActive() returns true (priority 100)
- Only Combat executes

Combat State:
- Active: CombatStrategy (priority 100)
- Behavior: Attack leader's target
- Bot facing: Enemy (SetFacingToObject from Task 2.3)
- Follow: Completely blocked

Combat End:
- Active: LeaderFollowBehavior (priority 50)
- Behavior: Return to following leader
- Bot facing: Leader

Validation:

• Issue #2: Ranged DPS combat should trigger (Combat gets exclusive control)
• Issue #3: Melee facing should be correct (Combat controls facing, Follow blocked)

---

Scenario 3: Melee Bot Facing Validation (Issue #3 Fix)

Objective: Verify melee bots face their target during combat, not the leader.

Test Steps:

1. Group with player leader and melee bot (Warrior, Rogue, Paladin)

4. VERIFY: Bot faces ENEMY, not leader
5. VERIFY: Bot performs melee attacks
6. VERIFY: Continuous facing updates (OnCombatUpdate)
7. Leader moves to different position
8. VERIFY: Bot stays facing enemy (Follow blocked)

Expected Behavior:

Before Fix (BROKEN):
- Follow strategy: Bot faces leader
- Combat strategy: Tries to set facing to enemy
- CONFLICT: Both strategies run, Follow wins
- Result: Bot faces leader, can't attack

After Fix (WORKING):
- Follow strategy: Blocked (priority 50 < 100)
- Combat strategy: Exclusive control (priority 100)
- SetFacingToObject(enemy): Works without interference
- Result: Bot faces enemy, attacks successfully

Validation Code:

// In ClassAI::OnCombatUpdate() (Task 2.3)
if (Unit* target = GetCombatTarget())
{
    float optimalRange = GetOptimalRange();
    if (optimalRange <= 5.0f)  // Melee range
    {
        bot->SetFacingToObject(target);  // Continuous facing update
    }
}

---

Expected Behavior:

Combat Start:
- ClassAI::OnCombatStart(target) called
- CombatTarget set to leader's target (Task 2.3)
- Follow blocked by priority system
- Combat executes exclusively

Ranged Combat:

- No Follow interference
- Smooth spell casting

Validation:

• Combat target should NEVER be NULL (Task 2.3 fix)
• Ranged abilities should execute (Combat exclusive control)

Troubleshooting

Issue: Bot Not Entering Combat

Symptoms:

• Leader attacks, bot stays following
• Bot doesn't acquire target

Debug Steps:

1. Check combat state transition:

   TC_LOG_DEBUG("playerbot", "Bot {} combat state: {}",
       bot->GetName(), ai->IsInCombat());
   

2. Check target acquisition:

   TC_LOG_DEBUG("playerbot", "Bot {} target: {}",
       bot->GetName(), ai->GetTarget().ToString());
   

3. Check strategy selection:

   Strategy* active = ai->GetPriorityManager()->GetActiveStrategy();
   TC_LOG_DEBUG("playerbot", "Active strategy: {}",
       active ? active->GetName() : "NULL");
   

Likely Cause: Combat state not transitioning (check OnCombatStart hook)

Issue: Melee Bot Still Facing Leader

Symptoms:

• Bot in combat but facing wrong direction
• Melee attacks not connecting

Debug Steps:

1. Check Follow strategy state:

   auto follow = ai->GetStrategy("follow");
   TC_LOG_DEBUG("playerbot", "Follow relevance: {}",
       follow->CalculateRelevance(ai));
   

2. Check mutual exclusion:

   bool excluded = ai->GetPriorityManager()->IsExclusiveWith(
       BehaviorPriority::COMBAT, BehaviorPriority::FOLLOW);
   TC_LOG_DEBUG("playerbot", "Combat excludes Follow: {}", excluded);
   

3. Check facing updates:

   // Add to ClassAI::OnCombatUpdate()
   TC_LOG_DEBUG("playerbot", "Setting facing to target: {}",
       target->GetName());
   

Likely Cause: Follow not properly excluded (check exclusion rules in constructor)

Issue: Performance Degradation

Symptoms:

• Server lag with many bots
• High CPU usage

Debug Steps:

1. Check strategy count:

   auto metrics = ai->GetPerformanceMetrics();
   TC_LOG_DEBUG("playerbot", "Strategies evaluated: {}",
       metrics.strategiesEvaluated);
   // Should always be 1
   

2. Profile update time:

   auto start = std::chrono::high_resolution_clock::now();
   ai->UpdateAI(diff);
   auto end = std::chrono::high_resolution_clock::now();
   auto duration = std::chrono::duration_cast<std::chrono::microseconds>(end - start);
   TC_LOG_DEBUG("playerbot", "Update time: {} μs", duration.count());
   

Likely Cause: Multiple strategies executing (check UpdateStrategies implementation)
