SetUpFixtureAttribute (NUnit 2.4) This is the attribute that marks a class that contains the one-time setup or teardown methods for all the test fixtures under a given namespace.

NUnit uses a very similar attribute style system just like the visual studio testing tools, but now we will be referring to a [TestClass] as a [TestFixture], and a [TestMethod] as simply a [Test]. [TestFixture] [TestClass] n/a: xUnit.net does not require an attribute for a test class; it looks for all test methods in all public (exported) classes in the assembly. But that wouldn’t make testing it flexible. Now we will run our first NUnit test case. For example we need to perform a unit test to a function where the function will get data from a file and we need to test the function 5 times with various input values and depending on the input value the file will be created. Also you may use TestFixture on a class but it is not must have. Ok, so let me discuss one real scenario using both of them. It could (in future) cache them and reuse them at will.

Insert the recorded or manual test calls Write your automation code into the Test1 method Use the ‘TestFixtureSetUp’ and ‘TearDown’ methods to initialize and set you Software Under Test (SUT) back to its original state 5.) The class may contain at most one method marked with the SetUpAttribute and one method marked with the TearDownAttribute. Lets assume that you have a project with this class: You need to test these methods and find bugs in them and despite how simple they appear, there are bugs in the above methods. Let’s add the Exception attribute to the following test … NUnit contains SetUp attribute which can be set on a choosen public method. I use it to unit test my Document Controller WPF application (.NET Framework 4.6.1) and in this project, the AutoMapper is heavily used to map domain models to view models. We have two projects CustomerOrderService project which is a class library and CustomerOrderService.Tests project which is a NUnit test project. MSTest v2 provides a way to declare methods to be called by the test runner before or after running a test. So you need to add a NuGet reference to it to write unit test cases and have them compiled. Provide a project name. By relying on C# syntax and standard interfaces in this way, the lifecycle of a test is clearer too; XUnit will construct and dispose the class for each test in the class, making it easy to see how each test will run. We'll learn more about NUnit Attribute in our next posts. It includes any dependencies and data needed. Nick has unfortunately missed the point of this post. This video is an introduction to testing in c# on the .Net framework.
