Game Test Framework Setup

Workflow ID: gds-test-framework Version: 1.0 (BMad v6)

Conventions

  • Bare paths (e.g. template.md) resolve from the skill root.
  • {skill-root} resolves to this skill's installed directory (where customize.toml lives).
  • {project-root}-prefixed paths resolve from the project working directory.
  • {skill-name} resolves to the skill directory's basename.

On Activation

Step 1: Resolve the Workflow Block

Run: python3 {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key workflow

If the script fails, resolve the workflow block yourself by reading these three files in base → team → user order and applying the same structural merge rules as the resolver:

  1. {skill-root}/customize.toml — defaults
  2. {project-root}/_bmad/custom/{skill-name}.toml — team overrides
  3. {project-root}/_bmad/custom/{skill-name}.user.toml — personal overrides

Any missing file is skipped. Scalars override, tables deep-merge, arrays of tables keyed by code or id replace matching entries and append new entries, and all other arrays append.

Step 2: Execute Prepend Steps

Execute each entry in {workflow.activation_steps_prepend} in order before proceeding.

Step 3: Load Persistent Facts

Treat every entry in {workflow.persistent_facts} as foundational context you carry for the rest of the workflow run. Entries prefixed file: are paths or globs under {project-root} — load the referenced contents as facts. All other entries are facts verbatim.

Step 4: Load Config

Load config from {project-root}/_bmad/gds/config.yaml and resolve:

  • user_name
  • communication_language

Step 5: Greet the User

Greet {user_name}, speaking in {communication_language}.

Step 6: Execute Append Steps

Execute each entry in {workflow.activation_steps_append} in order.

Activation is complete. If activation_steps_prepend or activation_steps_append were non-empty, confirm every entry was executed in order before proceeding. Do not begin the main workflow until all activation steps have been completed.

Goal

Initialize a production-ready game test framework for Unity, Unreal Engine, or Godot projects. This workflow scaffolds the complete testing infrastructure including unit tests, integration tests, and play mode tests appropriate for the detected game engine.

Role

You are a Game QA Architect specializing in test infrastructure. You detect the game engine in use, scaffold the appropriate test framework, generate working example tests, and produce documentation — leaving the team with a fully operational testing setup from day one.


WORKFLOW ARCHITECTURE

This workflow detects the game engine and creates all necessary test infrastructure files directly in the game project.

Primary Output: {test_dir}/README.md

Supporting Components:

  • Validation: {installed_path}/checklist.md

Knowledge Base References:

  • knowledge/unity-testing.md
  • knowledge/unreal-testing.md
  • knowledge/godot-testing.md

Load and resolve configuration from {module_config}:

output_folder: {from config}
user_name: {from config}
communication_language: {from config}
document_output_language: {from config}
game_dev_experience: {from config}
date: {system-generated}

Resolve workflow variables:

test_dir: "{project-root}/tests"    # Root test directory
game_engine: "auto"                  # auto | unity | unreal | godot
test_framework: "auto"               # auto | gut (godot) | unity-test-framework | unreal-automation

EXECUTION

Preflight Requirements

Critical: Verify these requirements before proceeding. If any fail, HALT and notify the user.

  • Game project exists with identifiable engine
  • No test framework already configured (check for existing test directories)
  • Project structure is accessible

Step 1: Detect Game Engine

Actions

  1. Identify Engine Type

Look for engine-specific files:

  • Unity: Assets/, ProjectSettings/ProjectSettings.asset, *.unity scene files
  • Unreal: *.uproject, Source/, Config/DefaultEngine.ini
  • Godot: project.godot, *.tscn, *.gd files
  1. Verify Engine Version

    • Unity: Check ProjectSettings/ProjectVersion.txt
    • Unreal: Check *.uproject file for EngineAssociation
    • Godot: Check project.godot for config_version
  2. Check for Existing Test Framework

    • Unity: Check for Tests/ folder, *.Tests.asmdef
    • Unreal: Check for Tests/ in Source, *Tests.Build.cs
    • Godot: Check for tests/ folder, GUT plugin in addons/gut/

Halt Condition: If existing framework detected, offer upgrade path or HALT.


Step 2: Scaffold Framework

Unity Test Framework

Knowledge Base Reference: knowledge/unity-testing.md

  1. Create Directory Structure

    Assets/
    ├── Tests/
    │   ├── EditMode/
    │   │   ├── EditModeTests.asmdef
    │   │   └── ExampleEditModeTest.cs
    │   └── PlayMode/
    │       ├── PlayModeTests.asmdef
    │       └── ExamplePlayModeTest.cs
    
  2. Generate Assembly Definitions

EditModeTests.asmdef:

   {
     "name": "EditModeTests",
     "references": ["<GameAssembly>"],
     "includePlatforms": ["Editor"],
     "defineConstraints": ["UNITY_INCLUDE_TESTS"],
     "optionalUnityReferences": ["TestAssemblies"]
   }

PlayModeTests.asmdef:

   {
     "name": "PlayModeTests",
     "references": ["<GameAssembly>"],
     "includePlatforms": [],
     "defineConstraints": ["UNITY_INCLUDE_TESTS"],
     "optionalUnityReferences": ["TestAssemblies"]
   }
  1. Generate Sample Tests

Edit Mode test example:

   using NUnit.Framework;

   [TestFixture]
   public class DamageCalculatorTests
   {
       [Test]
       public void Calculate_BaseDamage_ReturnsCorrectValue()
       {
           // Arrange
           var calculator = new DamageCalculator();

           // Act
           float result = calculator.Calculate(100f, 1f);

           // Assert
           Assert.AreEqual(100f, result);
       }
   }

Play Mode test example:

   using System.Collections;
   using NUnit.Framework;
   using UnityEngine;
   using UnityEngine.TestTools;

   public class PlayerMovementTests
   {
       [UnityTest]
       public IEnumerator Player_WhenInputApplied_Moves()
       {
           // Arrange
           var playerGO = new GameObject("Player");
           var controller = playerGO.AddComponent<PlayerController>();

           // Act
           controller.SetMoveInput(Vector2.right);
           yield return new WaitForSeconds(0.5f);

           // Assert
           Assert.Greater(playerGO.transform.position.x, 0f);

           // Cleanup
           Object.Destroy(playerGO);
       }
   }

Unreal Engine Automation

Knowledge Base Reference: knowledge/unreal-testing.md

  1. Create Directory Structure

    Source/
    ├── <ProjectName>/
    │   └── ...
    └── <ProjectName>Tests/
       ├── <ProjectName>Tests.Build.cs
       └── Private/
           ├── DamageCalculationTests.cpp
           └── PlayerCombatTests.cpp
    
  2. Generate Module Build File

<ProjectName>Tests.Build.cs:

   using UnrealBuildTool;

   public class <ProjectName>Tests : ModuleRules
   {
       public <ProjectName>Tests(ReadOnlyTargetRules Target) : base(Target)
       {
           PCHUsage = ModuleRules.PCHUsageMode.UseExplicitOrSharedPCHs;

           PublicDependencyModuleNames.AddRange(new string[] {
               "Core",
               "CoreUObject",
               "Engine",
               "<ProjectName>"
           });

           PrivateDependencyModuleNames.AddRange(new string[] {
               "AutomationController"
           });
       }
   }
  1. Generate Sample Tests

    #include "Misc/AutomationTest.h"
    
    IMPLEMENT_SIMPLE_AUTOMATION_TEST(
       FDamageCalculationTest,
       "<ProjectName>.Combat.DamageCalculation",
       EAutomationTestFlags::ApplicationContextMask |
       EAutomationTestFlags::ProductFilter
    )
    
    bool FDamageCalculationTest::RunTest(const FString& Parameters)
    {
       // Arrange
       float BaseDamage = 100.f;
       float CritMultiplier = 2.f;
    
       // Act
       float Result = UDamageCalculator::Calculate(BaseDamage, CritMultiplier);
    
       // Assert
       TestEqual("Critical hit doubles damage", Result, 200.f);
    
       return true;
    }
    

Godot GUT Framework

Knowledge Base Reference: knowledge/godot-testing.md

  1. Create Directory Structure

    project/
    ├── addons/
    │   └── gut/ (plugin files)
    ├── tests/
    │   ├── unit/
    │   │   └── test_damage_calculator.gd
    │   └── integration/
    │       └── test_player_combat.gd
    └── gut_config.json
    
  2. Generate GUT Configuration

gut_config.json:

   {
     "dirs": ["res://tests/"],
     "include_subdirs": true,
     "prefix": "test_",
     "suffix": ".gd",
     "should_exit": true,
     "should_exit_on_success": true,
     "log_level": 1,
     "junit_xml_file": "results.xml"
   }
  1. Generate Sample Tests

tests/unit/test_damage_calculator.gd:

   extends GutTest

   var calculator: DamageCalculator

   func before_each():
       calculator = DamageCalculator.new()

   func after_each():
       calculator.free()

   func test_calculate_base_damage():
       var result = calculator.calculate(100.0, 1.0)
       assert_eq(result, 100.0, "Base damage should equal input")

   func test_calculate_critical_hit():
       var result = calculator.calculate(100.0, 2.0)
       assert_eq(result, 200.0, "Critical hit should double damage")

Step 3: Generate Documentation

Create tests/README.md with:

  • Test framework overview for the detected engine
  • Directory structure explanation
  • Running tests locally
  • CI integration commands
  • Best practices for game testing
  • Links to knowledge base fragments

Step 4: Deliverables

Primary Artifacts Created

  1. Directory Structure — Engine-appropriate test folders
  2. Configuration Files — Framework-specific config (asmdef, Build.cs, gut_config.json)
  3. Sample Tests — Working examples for unit and integration tests
  4. Documentationtests/README.md
