Install NUnit Test Adapter
This test adapter is used as a bridge between Visual Studio and NUnit framework can be used from within Visual Studio IDE.
- Click Tools->Extensions and Updates…
- It will open Extensions and Updates dialog box , click online and Type nunit in the search box
- Click download button will download and install necessary components on your machine.
- After installation you have to restart visual studio
To implement NUnit in your Test Project
- Create your unit test project
- From menu Click PROJECT->Manage NuGet Package…
- You will presented NuGet Package Manger
- Click Online and type nunit in search dialog box
- Now click on the install button to install NUnit Package in the unit test project ,
Note: Make sure you have selected your unit test project. - Now NUnit is ready
- Reference project you want to test , in this case reference SimpleOrder.Business
- If you need some mocking install Moq in you test project.
- Everything is ready to write your test.
- Right click on your test Project and add UnitTest class
- In your test class make sure to replace the following namespace from using
using Microsoft.VisualStudio.TestTools.UnitTesting;
//by
using NUnit.Framework;
12. In your test class
Add class attribute [TestFixture] instead of [TestClass]
Add test method attribute [Test] instead of [TestMethod]
13. And our test method will be as shown below
