When to use:when you want a clean test context for every test (sharing the setup and cleanup code, without sharing the object instance). My TestCaseSource list doesn't change from run to run, its a static list built from the dll being tested, but I need to build the list once.

Once the project is set up, we install the SpecFlow, SpecFlow.NUnit, and SpecFlow.Tools.MsBuild.Generation packages. xUnit.net creates a new instance of the test class for every test that is run, so any code which is placed into the constructor of the test class will be run for every single test. Tagged on: Mocking, Moq, UnitTesting. Each test can be named differently like this. The TearDown method is executed once after all the fixtures have completed execution.

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 framework will create three different test cases using these three parameters. In this example, we have use three TestCase attributes on same method with different parameters. In the above example, we have fixed the result to true that means we can only check the above test case with positive parameters. Copyright © 2002-2018 Charlie Poole.
