Without it, your code may not work properly, and errors or bugs may go unnoticed until later in the development cycle. Visual Studio makes unit testing an integral part of development, with features that make it simple to create and run tests, and assess the results.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_Set_Up_Your_Test_Environment\"><\/span>1. Set Up Your Test Environment<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Creating a test project in Visual Studio is a must before testing your code. In the Solution Explorer, right-click your solution, select &#8220;Add,&#8221; and then &#8220;New Project.&#8221; From the options, choose &#8220;Test,&#8221; select &#8220;Unit Test Project,&#8221; and create a project to accommodate your tests.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"2_Create_Your_Test_Methods\"><\/span>2. Create Your Test Methods<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In Visual Studio, a test is a method that verifies a particular piece of code behaves accordingly. To make a test method, right-click on your test project and select &#8220;Add,&#8221; then choose &#8220;UnitTest.&#8221; This will generate a new test method containing the following starter code:<\/p>\n<p>&#8220;`csharp<br \/>\n[TestMethod]<br \/>\npublic void TestMethod1()<br \/>\n{<br \/>\n    \/\/ Arrange<\/p>\n<p>    \/\/ Act<\/p>\n<p>    \/\/ Assert<br \/>\n}<br \/>\n&#8220;`<\/p>\n<p>In the three commented regions, you will input your code to set up your test environment (Arrange), execute your code, and then confirm that what you expected to happen actually happened (Assert).<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_Write_Your_Test_Logic\"><\/span>3. Write Your Test Logic<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>After creating the test method, it&#8217;s now time to write out the logic. This typically involves generating data and objects for testing, running the code you want to test, and affirming that it worked as expected.<\/p>\n<p>For instance, let&#8217;s assume you have an add function that adds two numbers together:<\/p>\n<p>&#8220;`csharp<br \/>\npublic int Add (int a, int b)<br \/>\n{<br \/>\n    return a + b;<br \/>\n}<br \/>\n&#8220;`<\/p>\n<p>You can develop a test method to verify that the add function operates correctly such as the one below:<\/p>\n<p>&#8220;`csharp<br \/>\n[TestMethod]<br \/>\npublic void TestAddMethod()<br \/>\n{<br \/>\n    \/\/ Arrange<br \/>\n    int a = 5;<br \/>\n    int b = 10;<\/p>\n<p>    \/\/ Act<br \/>\n    int result = Add(a, b);<\/p>\n<p>    \/\/ Assert<br \/>\n    Assert.AreEqual(result, 15);<br \/>\n}<br \/>\n&#8220;`<\/p>\n<p>In this instance, you establish two variables that will hold the numerical values to be added, then pass these values to the Add function, storing the result in a variable. And finally, the Assert method verifies that the result is equal to the specified value of 15.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"4_Run_Your_Test\"><\/span>4. Run Your Test<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When done writing the test method, it is necessary to run it to see if your code works as expected. To do this, right-click on your test method in the Solution Explorer, and choose &#8220;Run Tests.&#8221; This action will initiate the test, and the outcomes of the test will be displayed in the Test Explorer.<\/p>\n<p>The Test Explorer will show which tests passed and which ones failed, as well as any problems or exceptions that happened during the test.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"5_Refine_Your_Tests\"><\/span>5. Refine Your Tests<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If any of your tests failed, you need to refine them. The process of refining the tests may involve making adjustments to the test data or logic or revising the code to deal with any recognized bugs.<\/p>\n<p>The task of refining your tests should continue until they accurately verify your code functions as expected in different scenarios, thus building confidence in the code.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Visual Studio has significantly simplified the unit testing process, enabling developers to assess\u00a0the overall behavior of the code early on in the development cycle. The process of writing and running tests is a simple process that doesn&#8217;t require much effort from you. Following the actionable steps above will enable you to write and run basic unit tests, facilitating the development of more efficient and stable code.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Unit Testing in Visual Studio Unit testing is an absolute must in the software development process.
