Question

How to replace MSTest with NUnit (C#)?

Answer 1

1. Add nuget package NUnit package into test project

   Install-Package NUnit
   

2. Remove the reference to Microsoft.VisualStudio.QualityTools.UnitTestFramework

3. Change the following namespace usings from

   using Microsoft.VisualStudio.TestTools.UnitTesting; 
   

   to

   using NUnit.Framework;
   

4. Search and replace the following:

   [TestClass] => [TestFixture]
   [ClassInitialize] => [TestFixtureSetUp]
   [ClassCleanup] => [TestFixtureTearDown]
   [TestInitialize] => [SetUp]
   [TestCleanup] => [TearDown]
   [TestMethod] => [Test]
   Assert.Ignore => Assert.Inconclusive
   

5. Unload project, open the .csproj file as Xml and remove line that looks like:

   <ProjectTypeGuids>{0b19334d-acce-4bf9-9475-088436fada27};{a9df11a7-84ef-49d2-b13a-9ed7e1f913e6}</ProjectTypeGuids>
   

6. Remove (or replace) private or internal modifiers and make sure the Test project has visibility to internal members. You can refer this link for InternalsVisibleTo.
