This article has been editorially reviewed by Suprotim Agarwal. In this article, I have discussed NUnit testing from scratch and how to incorporate it for Visual Studio 2015. Add test methods for the remaining functionality and you will get 100% code coverage. If you have not written any test methods for a piece of code, you will see red color for them (eg: Concat). You can add or remove columns as per your need and find colored statements. You can select Add and Remove Columns and you get following options. The data is shown for % of Blocks as not covered and covered. The Code Coverage window will be added automatically once the test methods are executed. If you want the data for all the tests, click on down arrow for Run and select Analyze Code Coverage for All Tests. With Visual Studio, we get blue and red colors which indicate portions of code that was reached, and the ones which was not reached while running the test.Ĭapturing Code Coverage data is very straight forward as we just need to select the method(s), right click and select Analyze Code Coverage for Selected Tests. Code Coverage for Test MethodsĬode Coverage is a process of finding out if the code you have written is being tested properly or not. We can change the data on the fly in the data file and every time the test method will be executed with different set of data. Now observe the TestSumCsvFile(int num) method with integer array as parameter and it executes for as many number of records in the csv file. I have yet again used a List and converted it to array in order to keep array length as flexible. Public string Concat(string str1, string str2) I have added a class library to the solution which has some methods for which we will write NUnit tests. Let us start from scratch by creating an empty solution in VS 2015. I am now going to walk you through the process of installation and use of Nunit framework. NUnit can be incorporated in Visual Studio by installing NuGet packages of NUnit. It is similar to Junit which is used for Java. NUnit is a unit testing framework which can be used for. Unit Tests are written by the same developers who are writing that unit of code. Visual Studio provides support for unit testing via the MS Test framework as well as third party frameworks like NUnit. Unit Testing is typically an automated functionality testing. Unit Testing in simple words is a testing process in which a unit of code is tested. Developers can also choose to install Visual Studio 2015 from web using the Web installer or download installation disc in.

I have briefly mentioned NUnit test with Visual Studio in one of my previous articles ( Code Quality Tools in Visual Studio 2015). Visual Studio portal provides different download and installation options for Visual Studio 2015 editions like Visual Studio Community 2015 RC or Visual Studio Enterprise 2015 RC. I will also show you how easy it is to compute the code coverage in Visual Studio 2015.

This article will describe all aspects of NUnit starting from Test Driven Development (TDD) to converting it to data driven test.
