About Unity Test Framework

The Unity Test Framework (UTF) enables Unity users to test their code in both Edit Mode and Play Mode, and also on target platforms such as Standalone, Android, iOS, etc.

This package provides a standard test framework for users of Unity and developers at Unity so that both benefit from the same features and can write tests the same way.

UTF uses a Unity integration of NUnit library, which is an open-source unit testing library for .Net languages. UTF currently uses NUnit version 3.5. For more information about NUnit, see the official NUnit website and the NUnit documentation.

Note: UTF is not a new concept or toolset; it is an adjusted and more descriptive naming for the toolset otherwise known as Unity Test Runner, which is now available as this package.
