In VS2015 and later, install the xunit.runner.visualstudio NuGet package. Then debugging is as easy as right-clicking on the test in the test explorer window. (Test–>Windows–>TestExplorer if you can’t see it). You can also right-click anywhere in the code of the test and Run Test and Debug Test will be in the context menu. If your test is not showing up, be sure the class and method are both public.
