This one helped me  Getting started with  NET unit testing using NUnit Basically   Add the NUnit 3 library in NuGet  Create the class you want to test  Create a separate testing class  This should have  TestFixture  above it  Create a function in the testing class  This should have  Test  above it  Then go into TEST WINDOW TEST EXPLORER  across the top   Click run to the left-hand side  It will tell you what has passed and what has failed   My example code is here  using System  using System Collections Generic  using System Linq  using System Text  using System Threading Tasks  using NUnit Framework   namespace NUnitTesting       class Program               static void Main string   args                                 public class Maths               public int Add int a  int b                        int x   a   b              return x                        TestFixture      public class TestLogging                Test          public void Add                         Maths add   new Maths                int expectedResult   add Add 1  2               Assert That expectedResult  Is EqualTo 3                       This will return true  and if you change the parameter in Is EqualTo it will fail  etc
