Moose Runner | A Test Runner with HotReload Integration

MooseRunner Overview

MooseRunner is a powerful test runner built to transform your development workflow both manual and with AI. Designed with a focus on speed and convenience, MooseRunner eliminates unnecessary time sinks by letting you test smarter, iterate faster, and stay fully immersed in the creative process.

Key Features

AI-enabled

• Allow Claude Code or other MCP using AI to use this tool if you get Unity-MCP https://github.com/CoplayDev/unity-mcp (not required but an option). As long as you have it installed it auto registers MooseRunner's MCP tool. 

Run Tests Seamlessly

• Execute single methods, entire classes, or all assemblies directly in PlayMode.
• Filter out the methods you are running at the moment to keep it clean by name or test attributes.
• MooseRunner cuts down on back-and-forth switching, saving time and reducing frustration.
• Speeds up iteration cycles (requires HotReload, for code changes).

Advanced Timescale Control

• Take complete control of your test execution speed with an interactive slider.
• Set custom speeds per method, including max speed, limited speed, or “run until” modes.
• Fast-forward to critical moments or step through frame by frame for precise debugging.

Uses Standard Attributes

• MooseRunner leverages Unity Test Runner attributes for full compatibility.
• Tests created with MooseRunner can also run with Unity Test Runner or integrate with regression pipelines.

Hot Reload Integration

• Automatically reruns your last executed test after a hot reload.
• This feature shortens your edit-test cycle, enabling rapid iteration and smooth development flow.

Task and UniTask Support

• Allows streamlined test execution with Task and UniTask methods, making tests more efficient. Also allows for cancellationTokens with timeout support to prevent infinite loops.

Use Cases

• Stay fully engaged in PlayMode with MooseRunner’s seamless TDD support for rapid iteration.Test-Driven Development (TDD) in PlayMode
• Accelerate long gameplay sequences, tutorials, or other extensive tests with dynamic timescale control.Time-Consuming Scenarios

Why MooseRunner?

MooseRunner was built to overcome the limitations of Unity’s Test Runner, which lacked Hot Reload compatibility, timescale flexibility, and Task support. Instead of settling, we created a custom solution to save time and iterate faster—and now, we’re sharing it with the developer community.
