Let us write code for the test method and find out how the tests passes. The tests methods are added and as we have added code for Assert Failure, both the test methods will fail as follows: I have added the methods to the existing test project In order to add Test Methods for the complete class, right click on it and select Create Unit Tests. Observe a blue bar appearing on the left and when you hover mouse over it, you will see that this code is not yet covered by any tests. Let us add some more code in the class library. Now that we have seen the approach for TDD, let us first add code to the class library and then create the test methods. The above figure shows the method implementation as well as the test method and ensures that the test has passed. Let us add the implementation for the method and see how the test automatically passes. The test method calls the proper code but as it does not have implementation, the test still fails. The above method shows the stub written in class library. Let us write the stub for the method in the class library. I will change the test method so as to use the class library. Let us start writing code for this test method in the class library and find out how the Live Unit Testing helps us.Īdd a project to the same solution of type class library and give it a name. The first test method fails (red color cross) as the two strings are not matching whereas in the second test method, the strings are matching so we see a green colored tick mark. (As expected in TDD, these test methods do not have any corresponding methods to test). I have written two test methods directly as follows. The moment you start writing code, the feature kicks in and you start getting real time results. The reference to NuGet package for MS Testing framework gets added automatically. In order to enable live unit testing select Test > Live Unit Testing > Start. As usual, you get a class with TestClass as the attribute and the method with TestMethod as attribute in it. Create a new test project using Visual Studio 2017 and provide a name to it.
Let us see a walkthrough of creating Live Unit Testing. It can be used with 3-unit testing frameworks namely MSTest, xUnit and NUnit. This feature is available in Visual Studio 2017 Enterprise Edition and for the projects using C# or VB.NET which are targeting. The results for test execution and code coverage are shown in real time. It runs the impacted unit tests in the background the moment you start editing code. Live Unit Tests also lets a developer know right away if he/she is breaking part of code or not. It gives impact of changes encountered on the existing tests. This feedback is given immediately while a developer is fixing a bug. Live Unit Testing gives the developer real time information directly while editing or writing code. It encourages Test Driven Development (TDD). Live Unit Testing helps in creating better quality code and also helps in finding code coverage. It only works with projects that are built upon the. This feature improves upon traditional unit testing to provide automation testing to achieve rapid development.Įditorial Note: As of this writing, Live Unit Testing currently does not work with.
In Visual Studio 2017(Enterprise Edition), Microsoft has introduced yet another very interesting feature called Live Unit Testing. In previous articles, I have discussed in details about the unit testing feature in Visual Studio, IntelliTest with Visual Studio and have taken overview of other automated tests like Web Test, Ordered Test, Load Tests. Unit Testing is an automated testing feature and has support in Visual Studio for MS Test framework as well as other third party frameworks like NUnit.

Unit Testing is a feature in software development where each unit/component/module is tested as soon as it is written.
