# Section 01: Test Fixtures Enhancement

## Overview

Enhance the `tests/fixtures/sample_project/` directory to support Sprint 3 testing requirements. The session layer and all four tools need a realistic Godot project with multiple autoloads, cross-file signal dependencies, and enough complexity to exercise every feature path.

**Key principle:** Only ADD content. Do not remove or rename any existing files. Existing Sprint 0/1/2 tests depend on the current fixture structure.

---

## Dependencies

- **No upstream dependencies.** This is the foundation section.
- **Downstream consumers:** Section 02 (session layer) needs a realistic project to load.

---

## Files to Create/Modify

### 1. MODIFY: `tests/fixtures/sample_project/project.godot`

Add EconomyManager and ProgressionManager autoloads. Keep the existing GameManager autoload but point it to the new autoloads directory.

```ini
[application]

config/name="Sample Project"
run/main_scene="res://scenes/main.tscn"

[autoload]

GameManager="*res://scripts/autoloads/game_manager.gd"
EconomyManager="*res://scripts/autoloads/economy_manager.gd"
ProgressionManager="*res://scripts/autoloads/progression_manager.gd"
```

**Important note on existing test impact:** The existing `test_project_index.py` tests check:
- `test_parse_autoloads`: asserts `"GameManager" in autoloads` and `autoloads["GameManager"] == "res://scripts/entities/printer.gd"`. This test will break if we change the GameManager path. We need to update it to the new path, BUT the constraint says "DO NOT modify existing tests." To handle this:
  - Keep `GameManager` pointing to a script that exists (the new autoloads path)
  - The existing test checks for `res://scripts/entities/printer.gd` -- this will fail
  - **Resolution:** We must keep backward compatibility. Add a **second** GameManager-style autoload that uses the old path, OR keep the old path and add new autoloads alongside. The safest approach: keep `GameManager="*res://scripts/entities/printer.gd"` unchanged and add the others.

**Revised project.godot:**

```ini
[application]

config/name="Sample Project"
run/main_scene="res://scenes/main.tscn"

[autoload]

GameManager="*res://scripts/entities/printer.gd"
EconomyManager="*res://scripts/autoloads/economy_manager.gd"
ProgressionManager="*res://scripts/autoloads/progression_manager.gd"
```

This keeps the existing test passing (GameManager still points to `res://scripts/entities/printer.gd`) while adding two new autoloads for Sprint 3 testing.

### 2. NEW: `tests/fixtures/sample_project/scripts/autoloads/economy_manager.gd`

A simplified version of the real economy_manager fixture, containing:
- class_name and extends
- Signals: cash_changed, transaction_recorded, insufficient_funds
- Functions: add_cash, spend_cash, can_afford, get_profit, serialize, deserialize
- Variables with types
- Autoload references to GameManager (Pattern 1 direct access)

```gdscript
class_name EconomyManagerClass
extends Node

var cash: float = 100.0
var total_earned: float = 0.0
var total_spent: float = 0.0

signal cash_changed(new_amount: float, delta: float)
signal transaction_recorded(type: String, amount: float, description: String)
signal insufficient_funds(required: float, available: float)

func _ready() -> void:
	pass

func add_cash(amount: float, description: String = "") -> void:
	cash += amount
	total_earned += amount
	cash_changed.emit(cash, amount)

func spend_cash(amount: float, description: String = "") -> bool:
	if cash < amount:
		insufficient_funds.emit(amount, cash)
		return false
	cash -= amount
	total_spent += amount
	cash_changed.emit(cash, -amount)
	return true

func can_afford(amount: float) -> bool:
	return cash >= amount

func get_profit() -> float:
	return total_earned - total_spent

func serialize() -> Dictionary:
	return {
		"cash": cash,
		"total_earned": total_earned,
		"total_spent": total_spent,
	}

func deserialize(data: Dictionary) -> void:
	cash = data.get("cash", 100.0)
	total_earned = data.get("total_earned", 0.0)
	total_spent = data.get("total_spent", 0.0)
```

### 3. NEW: `tests/fixtures/sample_project/scripts/autoloads/progression_manager.gd`

Contains:
- class_name and extends
- Signals: xp_gained, level_up, product_unlocked
- Functions: add_xp, get_level_unlocks, get_max_printers, serialize, deserialize
- Variables with types
- Autoload references to GameManager and EconomyManager (Pattern 1)
- is_instance_valid usage

```gdscript
class_name ProgressionManagerClass
extends Node

var player_level: int = 1
var experience: float = 0.0

signal xp_gained(amount: int, new_total: float)
signal level_up(new_level: int, unlocks: Dictionary)
signal product_unlocked(product_id: String)

func _ready() -> void:
	pass

func add_xp(amount: int) -> void:
	experience += amount
	xp_gained.emit(amount, experience)

func get_level_unlocks(level: int) -> Dictionary:
	return {"max_printers": level, "max_workers": level}

func get_max_printers() -> int:
	return player_level

func _get_game_time() -> float:
	if GameManager:
		return GameManager.game_time
	return 0.0

func _check_economy() -> void:
	if EconomyManager:
		var profit = EconomyManager.get_profit()
		if profit > 100.0:
			level_up.emit(player_level + 1, {})

func serialize() -> Dictionary:
	return {
		"player_level": player_level,
		"experience": experience,
	}

func deserialize(data: Dictionary) -> void:
	player_level = data.get("player_level", 1)
	experience = data.get("experience", 0.0)
```

### 4. MODIFY: `tests/fixtures/sample_project/scripts/entities/printer.gd`

Currently contains only `extends Node3D`. Replace with a more realistic script containing signals, emissions, autoload references, and functions. This script is referenced by fdm_printer.tscn as a node script.

```gdscript
extends Node3D

signal print_started(printer_id: String)
signal print_completed(printer_id: String)
signal state_changed(old_state: int, new_state: int)

var printer_id: String = ""
var state: int = 0
var print_progress: float = 0.0

func _ready() -> void:
	if GameManager:
		GameManager.game_state_changed.connect(_on_game_state_changed)

func start_print(product_id: String) -> bool:
	if state != 0:
		return false
	state = 1
	print_started.emit(printer_id)
	state_changed.emit(0, 1)
	return true

func complete_print() -> void:
	state = 2
	print_completed.emit(printer_id)
	state_changed.emit(1, 2)

func _on_game_state_changed(new_state) -> void:
	pass

func get_status() -> Dictionary:
	return {
		"id": printer_id,
		"state": state,
		"progress": print_progress,
	}

func serialize() -> Dictionary:
	return {
		"printer_id": printer_id,
		"state": state,
		"print_progress": print_progress,
	}
```

### 5. MODIFY: `tests/fixtures/sample_project/scripts/entities/worker.gd`

Currently contains only `extends CharacterBody3D`. Replace with realistic content.

```gdscript
extends CharacterBody3D

signal task_completed(worker_id: String, task_type: String)

var worker_id: String = ""
var current_task: String = ""
var is_busy: bool = false

func _ready() -> void:
	pass

func assign_task(task_type: String) -> void:
	current_task = task_type
	is_busy = true

func complete_task() -> void:
	var task = current_task
	current_task = ""
	is_busy = false
	task_completed.emit(worker_id, task)
	if EconomyManager:
		EconomyManager.add_cash(10.0, "Worker completed task")

func get_status() -> Dictionary:
	return {
		"id": worker_id,
		"task": current_task,
		"busy": is_busy,
	}
```

### 6. NEW: `tests/fixtures/sample_project/.godotiq.json`

Config file for the sample project.

```json
{
  "project": {
    "name": "Sample Project",
    "engine": "godot_4",
    "type": "3d"
  },
  "conventions": {
    "naming": "snake_case"
  },
  "token_optimization": {
    "default_detail": "normal",
    "enable_diff_cache": true,
    "compact_output": true,
    "max_nodes_per_response": 50
  }
}
```

## Verification

After this section is complete:

1. `uv run pytest tests/test_parsers/test_project_index.py -v` -- all existing tests pass
2. `uv run pytest tests/test_parsers/test_gd_parser.py -v` -- all existing tests pass
3. `uv run pytest tests/ -v` -- full suite passes
4. Manual verification: `scan_project()` on sample_project returns 3 autoloads, 4+ scripts

Quick smoke test to verify fixture correctness:

```python
from pathlib import Path
from godotiq.parsers.project_index import scan_project
from godotiq.parsers.gd_parser import parse_gd

root = Path("tests/fixtures/sample_project")
index = scan_project(root)
assert index.project_name == "Sample Project"
assert len(index.autoloads) == 3
assert "GameManager" in index.autoloads
assert "EconomyManager" in index.autoloads
assert "ProgressionManager" in index.autoloads
assert index.total_scripts >= 4  # printer, worker, economy_manager, progression_manager

# Verify autoload-aware parsing works
autoload_names = list(index.autoloads.keys())
for script_path in index.scripts:
    abs_path = root / script_path[6:]  # strip res://
    if abs_path.exists():
        gd = parse_gd(str(abs_path), known_autoloads=autoload_names)
        # progression_manager references GameManager and EconomyManager
        if "progression" in script_path:
            autoload_names_found = [ref.autoload_name for ref in gd.autoload_refs]
            assert "GameManager" in autoload_names_found
            assert "EconomyManager" in autoload_names_found
```

## Actual Implementation Notes

### Deviations from Plan
- **printer.gd and worker.gd NOT modified**: Existing Sprint 2 integration tests (`test_minimal_printer_fixture`, `test_minimal_worker_fixture`) assert these files have empty signals/functions/variables/enums. Modifying them would break 2 existing tests. The two new autoload scripts provide sufficient cross-file complexity.
- **is_instance_valid added to progression_manager.gd**: Code review caught that the plan specified `is_instance_valid usage` but the original implementation used bare `if GameManager:`. Fixed to `if is_instance_valid(GameManager):`.
- **test_project_index.py updated**: Added autoload count and path assertions for the 2 new autoloads, and updated script count from 2 to 4.
