The goal of Unit Testing is to write test code that tests production code. Unit Testing can be an amazing driver of quality or an expensive epic fail. Here are some best practices to make sure it the former, a driver of quality, instead of the latter, an epic fail.

Learn how to create unit tests for controller actions. In this tutorial, Stephen Walther demonstrates how to test whether a controller action returns a particular view, returns a particular set of data, or returns a different type of action result. The goal of this tutorial is to demonstrate how you can write unit tests for the controllers in your ASP. NET MVC applications. We discuss how to build three different types of unit tests. You learn how to test the view returned by a controller action, how to test the View Data returned by a controller action, and how to test whether or not one controller action redirects you to a second controller action. Creating the Controller under Test Let’s start by creating the controller that we intend to test. The controller, named the Product Controller, is contained in Listing 1. Listing 1 – Product Controller.cs using System; using System. Web. Mvc; namespace Store. Controllers public class Product Controller : Controller public Action Result Index / Add action logic here throw new Not Implemented Exception public Action Result Details(int Id) return View( Details The Product Controller contains two action methods named Index and Details. Both action methods return a view. Notice that the Details action accepts a parameter named Id. Testing the View returned by a Controller Imagine that we want to test whether or not the Product Controller returns the right view. We want to make sure that when the Product Controller. Details action is invoked, the Details view is returned. The test class in Listing 2 contains a unit test for testing the view returned by the Product Controller. Details action. Listing 2 – Product Controller Test.cs using System. Web. Mvc; using Microsoft. Visual Studio. Test Tools. Unit Testing;.
Unit tests give developers and testers a quick way to check for logic errors in the methods of classes in C, Visual Basic. NET, and C+ projects. A unit test can be created one time and run every time that source code is changed to make sure that no bugs are introduced. This topic covers how to use Visual Studio Team System unit testing tools to automatically generate the skeleton for a unit test from existing code, add validation to fill in that skeleton, create a test list, run a test, and read code coverage results.

The following figure shows the Create Unit Tests dialog box, which appears when you right-click in a code file that contains methods and then click Create Unit Tests. Unit tests are generated for all the methods that you select in the Types list of the dialog box. The following figure shows that in this example, unit tests will be generated for the Credit and Debit methods. After you have generated your unit tests, a code file is created and there are changes made in your solution explorer. The following figure shows the results of creating the unit tests. A separate unit test is created for each method that you select in the Create Unit Test dialog box. In this example, we generated unit tests for the Credit and Debit methods. Each unit tests that is generated has empty variables and a placeholder Assert statement. The default placeholder Assert statement is usually the Assert. Inconclusive statement. To make the test meaningful, you have to initialize the.
