This repository is the home for Microsoft.Testing.Platform and extensions, as well as MSTest.

Microsoft.Testing.Platform is a lightweight alternative to VSTest. For more information, see [Microsoft.Testing.Platform overview](https://aka.ms/mtp-overview).

MSTest, Microsoft Test Framework, is a testing framework for .NET applications. It allows you to write tests, use Test Explorer, create test suites, and apply the red, green, and refactor patterns to write code.

This is a fully supported, open source, and cross-platform test framework with which to write tests targeting .NET Framework, .NET Core, .NET, UWP, and WinUI on Windows, Linux, and Mac.
