NUnit Tool – Used for Test driven development
• Lets create a sample banking class named account
which supports operations to deposit, withdraw or
transfer funds.
• To get started, lets create a new project, and select
project type as Visual C# - Class Library
• Also give the location as C:\Documents and
Settings\smktb\My Documents\Visual Studio
2005\Projects -- with your respective username and give
the name to the Class Library as TestNUnit
New Class Library
Rename the class name to Account.cs from Class1.cs
Add NUnit Reference by selecting your project name, right click and
add reference as shown below
Add a new class “TestAccount.cs” and add the below code. Also add
the namespace “using NUnit.Framework” and then build the solution
Start NUnit GUI from Programs-Applications-NUnit-Net-2.0 – NUnit
GUI. Click on File-Open-Select the folder where your program is stored,
go to the bin directory and select TestNUnit.dll
Click on Run to check the output. In this case, the test case will fail, as
we did not invoke destination.Deposit(amount).
In order to correct the error, lets uncomment the line in Account.cs file
which says “destination.Deposit(amount)”. Important points to note is
that [TestFxture] denotes that the corresponding class contains a “Test
Case” and [Test] indicates that the corresponding function is a test case
