Microsoft.IdentityModel.Clients.ActiveDirectory vs NUnit3TestAdapter

This package contains the binaries of the Active Directory Authentication Library (ADAL). ADAL provides easy to use authentication functionality for your .NET based client by taking advantage of Windows Server Active Directory and Azure Active Directory. ADAL.NET enables you to acquire a security token to access protected Web APIs, for instance Microsoft Graph or your own Web API. ADAL.NET is built against multiple platforms, including .net desktop, .net standard, .net core, UWP, Xamarin iOS and Xamarin Android. It can be called from applications and Web APIs (ASP.NET, .NET Core, ASP.NET Core) that call other Web APIs in the name of a user, or without a user.

A package including the NUnit 3 TestAdapter for Visual Studio 2012 onwards. With this package you don't need to install the VSIX adapter package, and you don't need to upload the adapter to your TFS server. Note that this package ONLY contains the adapter, not the NUnit framework. You must also get the framework. For VS 2017 and forward, you should add this package to every test project in your solution. (Earlier versions only require a single adapter package per solution.) The package works with Visual Studio 2012 and newer.
