How to execute unit test in VSIX debug mode?

I have a Visual Studio extension (VSIX) which has a button inside a window. When clicking on button, how can I run a specific unit test in debug mode?

The same thing that VS Test Explorer is doing, right clicking on test case and click Debug Unit Test. I would like to do the same approach when clicking a button from VSIX. Any idea how to debug unit test from VSIX?
