I was going through the various articles throughout the web to figure out how to setup testing.
"Open up your launch.config..."
"Type a bunch of various junk"
Or like all things keep going until you find something stupid simple.
Stupid Simple Method
Open up your VSCode instance.
Open your package.json file
Notice the icon VSCode puts above the scripts block.
Select the script that you have created to run your tests from the command line.
After going through that process the first time, you can go into your terminal (ctrl+`) and run your command line
npm run test/yarn test and it will attach a debugger automatically. Even easier!
