Build System

Module Setup (Build.cs)

// Source/UnrealFrog/UnrealFrog.Build.cs
using UnrealBuildTool;

public class UnrealFrog : ModuleRules
{
    public UnrealFrog(ReadOnlyTargetRules Target) : base(Target)
    {
        PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
        PublicDependencyModuleNames.AddRange(new string[] {
            "Core", "CoreUObject", "Engine", "InputCore",
            "EnhancedInput", "UMG"
        });

Target Files

• UnrealFrog.Target.cs — Game target (shipping build)
• UnrealFrogEditor.Target.cs — Editor target (development)

Testing Framework

Automation Tests

#include "Misc/AutomationTest.h"

// Simple unit test
IMPLEMENT_SIMPLE_AUTOMATION_TEST(
    FScoreSystemTest,
    "UnrealFrog.Gameplay.ScoreSystem",
    EAutomationTestFlags::ApplicationContextMask | EAutomationTestFlags::ProductFilter
)

bool FScoreSystemTest::RunTest(const FString& Parameters)
{
    // Arrange
    UScoreSubsystem* Score = NewObject<UScoreSubsystem>();

    // Act
    Score->AddPoints(100);

    // Assert
    TestEqual("Score should be 100", Score->GetCurrentScore(), 100);
    return true;
}

Functional Tests (In-Game)

// AFroggerFunctionalTest inherits from AFunctionalTest
// Place in test maps, run via automation framework
UCLASS()
class AFrogHopTest : public AFunctionalTest
{
    GENERATED_BODY()
public:
    virtual void StartTest() override;
    virtual void Tick(float DeltaTime) override;
};

Running Tests

# Run all project tests
UnrealEditor-Cmd UnrealFrog.uproject -ExecCmds="Automation RunTests UnrealFrog" -NullRHI -NoSound

# Run specific test group
UnrealEditor-Cmd UnrealFrog.uproject -ExecCmds="Automation RunTests UnrealFrog.Gameplay"

# Run with Gauntlet (CI-friendly)
RunUAT.bat RunUnrealTests -project=UnrealFrog.uproject -test=UnrealFrog

Asset Validation

Data Validation Plugin

Enable DataValidation plugin. Create validators:

UCLASS()
class UAssetNamingValidator : public UEditorValidatorBase
{
    GENERATED_BODY()
public:
    virtual EDataValidationResult IsValid(TArray<FText>& ValidationErrors) override;
};

Naming Convention Checks

Python Editor Scripting

import unreal

# Import an asset
task = unreal.AssetImportTask()
task.filename = "path/to/model.fbx"
task.destination_path = "/Game/Meshes/Characters"
task.automated = True
task.replace_existing = True
unreal.AssetToolsHelpers.get_asset_tools().import_asset_tasks([task])

# Validate assets
validator = unreal.EditorValidatorSubsystem()
validator.validate_assets_with_settings(assets, settings)
