SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill automates the creation of comprehensive C++ unit tests for Unreal Engine projects, ensuring code quality and robustness by identifying edge cases and integration errors.

Core Features & Use Cases

  • Automated Test Generation: Creates production-quality unit and functional tests for C++ code.
  • Ultrathink Analysis: Identifies exhaustive edge cases, mutation-based errors, and coverage gaps.
  • Use Case: When developing a new gameplay ability in UE5, use this Skill to automatically generate a full suite of tests covering all possible player inputs, game states, and potential integration issues with other systems like combat or AI.

Quick Start

Use the create-unittest skill to generate tests for the FSipherAsyncLoader class.

Frequently Asked Questions about create-unittest

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate C++ unit tests for an Unreal Engine 5 project?▼

You can generate C++ unit tests by providing existing C++ source files or technical documentation directly. The tool analyzes the code or specs to automatically create test suites covering edge cases and integration errors.

What is ultrathink analysis for C++ unit testing?▼

Ultrathink analysis is an advanced processing mechanism that identifies exhaustive edge cases, mutation-based errors, and coverage gaps in C++ code. It ensures comprehensive test generation by deeply evaluating potential integration errors within Unreal Engine projects.

Can I generate tests from a PRD or technical documentation instead of existing code?▼

Yes, spec-first generation supports creating C++ unit tests directly from PRDs or technical documentation. This allows you to define test cases and expected behaviors before writing the actual gameplay ability or system code.

Does this automated test generation work with Unreal Engine project structures?▼

Yes, the tool is built specifically for Unreal Engine 5 projects and follows UE5 project structure rules. It automatically detects fixtures and determines the correct output locations for generated test files.

What is the best way to find edge cases in Unreal Engine C++ gameplay abilities?▼

The best way to find edge cases is using automated ultrathink analysis on your C++ source files. It identifies exhaustive edge cases, mutation-based errors, and coverage gaps specific to gameplay abilities and system integration issues.

What are the limitations of automated C++ unit test generation for UE5?▼

Automated C++ unit test generation requires clear C++ source files or detailed PRDs to function accurately. While it identifies edge cases and integration errors, it cannot replace manual testing for complex runtime behaviors unique to your specific Unreal Engine game logic.
