Add `-Watch` switch

[dfinke]

This would enable the watching of file & directory trees, and enable continuous testing at the console.

Hmm... how do you see this behaving with the various Output options? Separate parameter set that only writes to the console and nothing else? Run until you hit Control+C or something and then output to PassThru / file / etc? Constant output to file?

[dfinke]

I don't know ;-)

I'm using vs code and have not taken the time to setup a Pester task. I make code changes, switch back to the console, up arrow and press enter. If I had a -watch, it'd be done

Have you tried https://github.com/smurawski/PowerShellGuard ? Same idea, just a separate module.

[dfinke]

Yeah, I like things in one place. Figured it be nice feature. No additional dependencies or figuring out how to wire it up, just do a -Watch. Guess I'm spoiled from npm

If I could vote this up 1000 times...

I've written a module to support -Watch like we would have in javascript if anyone wants to use it feel free. I am going to shove in the gallery.

Invoke-PesterWatcher -WatchFolder . -PesterOptions etc

(forwards all pester arguments onto pester)

@GoEddie Thank you for your contribution. There are other projects that do the same or similar thing, but it does not hurt to have another one. If you want you can add your project to our list of projects connected to Pester.
