Unity Test Framework

What Unity Test Framework does

Unity's built-in testing package. Write automated Edit Mode and Play Mode tests in C# (based on NUnit) to catch bugs before players do. It is listed in our Playtesting & QA category.

Pricing and free tier

Unity Test Framework is listed as free. Plans change often, so confirm on the official site before you pay.

Best use for beginner game devs

We rate Unity Test Framework 2/5 for beginners, which makes it better suited to experienced developers than to a first project. Free and already in your project, but writing tests is a coding skill.

Best for: Unity projects that keep breaking when you change things. It ships with the Unity Editor and is included in projects made with Unity 2019.2 or later (checked Oct 23, 2026).
