A Test Developer's blog: How to write NUnit Test Cases?
Unit Testing is very important in Test Driven Development (TDD) where the development starts with writing test cases before code. Lot of testing frameworks are available for doing better unit testing in different languages. For .NET there are frameworks like NUnit, TestDriven.NET, xUnit.net and more.
Now click on the Install button to install the NUnit package in the unit test project. You are now ready to write and run NUnit tests from within Visual Studio IDE. As an example let's write a simple unit test using NUnit that tests the GetEmployeeByID() method you created earlier.
Abstract. This article looks at unit testing patterns and describes the main patterns found in tested .NET code.It also describes the problems with each pattern. We will be using nUnit for our examples. For more information, see nUnit and Test Driven Development.Read the below nUnit tutorial to get more information on Nunit Unit testing and download Typemock Isolator for.
A reasonable combination of unit and integration tests ensures that every single unit works correctly, independently from others, and that all these units play nicely when integrated, giving us a high level of confidence that the whole system works as expected.

If any code in the test raises an ArgumentNullException, this test will pass. Suppose that a bug in the SampleComponent constructor produces an ArgumentNullException? This test will pass! Not what we want in a robust unit test. To counter this, the nUnit framework (as well as some of the other frameworks) added an Assert.Throws method.
ReSharper provides a unit test runner that helps you run and debug unit tests based on NUnit, xUnit.net, MSTest, QUnit and Jasmine. You can explore tests, group them in different ways, break them down into individual sessions, see test output and navigate to source code from stack traces.
