How can I run unit tests after build with Visual Studio 2015 Professional?

I have created some unit tests for my C# web application. What I would like to do next, is to run the unit tests automatically, each time I build my application.

I understand that you have a "Run unit tests after build" option in Visual Studio 2015 Enterprise Edition, which will do just that. But unfortunately I have only the Professional edition, which seems not to offer this feature.

Is there some other way to to run unit tests automatically, when building the code using the Professional editon of Visual Studio 2015?
