# Phase 5: Testing & Iteration Guide

## Overview
This phase documents the testing protocol for validating audio mod fixes and improvements.

**Note:** Actual testing must be performed by playing the game. This document provides the testing workflow and evaluation criteria.

---

## Pre-Testing Checklist

### 1. BepInEx Installation
- [ ] BepInEx installed in game directory
- [ ] `winhttp.dll` present in game root
- [ ] `BepInEx\LogOutput.log` generated after first run

### 2. Plugin Installation
- [ ] `HomuraHimeAudioMod.dll` in `BepInEx\plugins\`
- [ ] Config file generated at `BepInEx\config\com.homurahime.audiomod.cfg`

### 3. Original Bank Backup
- [ ] Original banks backed up to `backup_banks_original\`

### 4. FMOD Banks (Optional)
- [ ] Modified banks copied to game directory (if using Phase 3 FMOD changes)

## Testing Scenarios

### Test 1: Quiet Exploration (Baseline)

**Purpose:** Verify mod doesn't break normal audio

**Steps:**
1. Launch game with mod enabled
2. Start new game or load save
3. Move through quiet area (hub, menu, cutscenes)
4. Listen for 5+ minutes

**Success Criteria:**
- [ ] No audio distortion or pops
- [ ] BGM plays smoothly without cutting out
- [ ] UI sounds (menu navigation) work correctly
- [ ] No crashes or errors in LogOutput.log

**Log Check:**
```
Filter: Look for "HomuraHimeAudio" entries
Expected: "initialized successfully"
```

---

### Test 2: Combat with 3+ Enemies

**Purpose:** Test voice limit fixes under moderate load

**Steps:**
1. Find an area with 3+ enemies (early game stages)
2. Engage in combat
3. Observe audio behavior during:
   - Multiple attack impacts
   - Enemy death sounds
   - Player attack sounds
   - Dodge/roll sounds

**Success Criteria:**
- [ ] No audio distortion during impact sounds
- [ ] Sounds don't cut out prematurely
- [ ] Enemy voices don't override each other harshly
- [ ] Can distinguish individual sound sources

**Failure Signs:**
- Crackling/popping sounds
- Sudden audio cutoff
- "Muffled" audio
- Missing sound effects

---

### Test 3: Boss Fights (Heavy Load)

**Purpose:** Stress test audio system

**Steps:**
1. Enter boss arena
2. Engage boss
3. Observe during:
   - Boss special attacks
   - Phase transitions
   - Multiple minions spawning
   - Intense combo sequences

**Success Criteria:**
- [ ] No audio glitches during phase transitions
- [ ] Music continues playing smoothly
- [ ] Voice lines play without cutoff
- [ ] Attack sounds remain distinguishable

**Challenge:** If glitches occur, reduce `MaxVoiceCount` in config

---

### Test 4: Swarm Enemy Encounters

**Purpose:** Test rapid sound triggering

**Steps:**
1. Find area with many weak enemies (swarms)
2. Use area-of-effect attacks
3. Observe:
   - Rapid footstep sounds
   - Multiple death sounds
   - Attack impact sounds overlapping

**Success Criteria:**
- [ ] No stuttering or repeating sounds
- [ ] Audio doesn't "stick" or loop
- [ ] Clean sound transitions

---

### Test 5: Enemy Behavior State Changes

**Purpose:** Validate enemy audio indicator improvements

**Steps:**
1. Approach enemies and observe state changes
2. Listen for audio cues during:
   - Enemy idle (subtle ambient)
   - Enemy alert (noticing player)
   - Enemy chase (pursuing)
   - Enemy attack (warning + strike)

**Success Criteria:**
| State | Expected Audio |
|-------|----------------|
| Idle | Subtle, low-volume ambient |
| Alert | Distinct warning/notice sound |
| Chase | Intensified pursuit audio |
| Attack | Clear attack indicator + impact |

**Rating Scale:**
- 1: Cannot hear/identify
- 2: Barely audible
- 3: Audible but unclear
- 4: Clear and distinguishable
- 5: Very distinct and helpful

## Metrics Tracking

### Audio Glitch Rating

| Rating | Description |
|--------|-------------|
| 0 | No glitches ever |
| 1 | Rare glitches (<1 per minute) |
| 2 | Occasional glitches (1-5 per minute) |
| 3 | Frequent glitches (>5 per minute) |
| 4 | Constant glitches |

### Target: Rating 0-1 for all scenarios

---

## Configuration Tuning

### If Distortion/Pops Occur

```ini
[VoiceManager]
MaxVoiceCount = 64  ; Reduce from 128

[Ducking]
DuckFadeTime = 0.08  ; Increase for smoother transitions
```

### If Sounds Cut Out

```ini
[VoiceManager]
MaxVoiceCount = 256  ; Increase if hardware supports
EnableVoiceLimitFix = true
```

### If Enemy Cues Unclear

```ini
[EnemyAudio]
EnemyIndicatorBoost = 1.5
AlertSoundBoost = 1.6
AttackSoundBoost = 1.4
```

| `HomuraHime Audio Mod initialized` | Plugin loaded OK |
| `Voice count X exceeds limit Y` | Voice limiting active |
| `DuckVolume adjusted` | Ducking patch working |
| `Enemy voice event: X` | Enemy audio hook active |
