Yes! The new Visual Studio 2026 edition is available in preview (now called Insiders). I'll take some time this week to walk through some of the features I like and maybe some of the rough edges I discover along the way.
Today I want to take a look at Code Coverage in Visual Studio. “Wait… what?!” I here you think, “Code coverage is not a new feature in Visual Studio.”. And yes you are right, But until this version Code Coverage was only available for the Enterprise Edition of Visual Studio.
With Visual Studio 2026, it is finally a part of the Community and Professional Edition as well. (I always thought it was strange to call yourself professional but don’t focus on code coverage.)
How to use Code Coverage in Visual Studio
So, if you never had the opportunity to use the Code Coverage feature in Visual Studio, let me walk you through the steps.
Go to the Test menu and select the Analyze Code Coverage for All Tests option from the menu.
Another option is to right click on a set of tests in the Test Explorer and select the Analyze Code Coverage option from the context menu.
Once the code coverage analyzer has completed its job, you can see the results on the Code Coverage Results window.
Here you can see the coverage percentage on Assembly, Class and Method level.
The coverage percentage can also be highlighted in the editor making it really easy to identify what parts of your code are still missing tests. Therefore, click on the Show Code Coverage Coloring icon in the Code Coverage Results window:
I’m really happy that this feature finally made it into all editions.
