NUnit is a unit-testing framework for all .NET languages.It can run on macOS, Linux and Windows operating systems.NUnit can be used for a wide range of testing, from unit testing with TDD to full fledged system and integration testing.It is a non-opinionated, broad and deep framework with multiple different ways to assert that your code behaves as expected. Many aspects of NUnit can be extended to suit your specific purposes.

The latest version, version 4, is an upgrade from the groundbreaking NUnit 3 framework. It is a modernized version, aimed at taking advantage of the latest .NET features and C# language constructs.

If you are upgrading from NUnit 3, be aware of thebreaking changes. Please see theNUnit 4 Migration Guide and take care to prepare your NUnit 3 code before you do the upgrade.

• NUnit Test Framework - The test framework used to write NUnit tests (this repository)
• NUnit Visual Studio Adapter - Visual Studio/Dotnet adapter for running NUnit 3 and 4 tests in Visual Studio or thedotnet command line.
• NUnit Console and Engine - Runs unit tests from the command line and provides the engine that is used by other test runners to run NUnit tests.

• NUnit Visual Studio Adapter - Visual Studio adapter for running NUnit 3 and 4 tests in Visual Studio or thedotnet command line.
• NUnit Visual Studio Templates - Project templates and snippets for writing unit tests in Visual Studio. This repo is for reference only, as the templates have been donated to theDotnet project and are maintained there, and also released as part of the dotnet releases.
• Visual Studio Test Generator - Generates NUnit tests in Visual Studio
• NUnit 2 Visual Studio Adapter - Visual Studio adapter for running older NUnit 2.x tests in Visual Studio and in VSTS/TFS builds

• NUnit 2 Driver - Allows the NUnit 3 engine to run NUnit 2 tests
• NUnit 2 Result Writer - Writes test results in the legacy NUnit 2 format
• Visual Studio Project Loader - Loads and parses Visual Studio projects and solutions
• NUnit Project Loader - Loads NUnit projects
