Support test files alongside source like Pester suggests

[sjwestern]

Is it possible to have test files next to their source files instead of in a separate directory?
This seems to be pretty standard and is the Pester docs recommended way of doing it.

Well, obviously I disagree that it's standard or the best way (and Pester itself certainly doesn't do that) but I would be happy to add support for Exclude. Honestly, I think we could even add a default Exclude = "*.Tests.ps1" although it would technically be a breaking change, so maybe not worth it.

You can easily hard code that in a fork for yourself though. You would just need to change line 206 of Build-Module.ps1

            # SilentlyContinue because there don't *HAVE* to be functions at all
            $AllScripts = Get-ChildItem -Path @($ModuleInfo.SourceDirectories).ForEach{ Join-Path $ModuleInfo.ModuleBase $_ } -Filter *.ps1 -Recurse -ErrorAction SilentlyContinue

to add -Exclude *.tests.ps1 like:

            # SilentlyContinue because there don't *HAVE* to be functions at all
            $AllScripts = Get-ChildItem -Path @($ModuleInfo.SourceDirectories).ForEach{ Join-Path $ModuleInfo.ModuleBase $_ } -Filter *.ps1 -Exclude *.tests.ps1 -Recurse -ErrorAction SilentlyContinue

I filed an issue against the Pester docs, because I can't find anyone who does that. I think they're talking about it from a "my first PowerShell script" practice, not module developers.

@sjwestern putting test files next to your production files is just one of the ways to structure your projects. Pester suggests it as an option, because it is the simplest way to do it for simple projects. More advanced projects are usually split their code into src and tst / test / tests folder. The guidance in Pester docs was updated to reflect that.

Thanks @Jaykul and @nohwnd appreciate your time.
If that's what most PowerShell module projects do then I'll stick with that.
I had just noticed the suggestion in Pester docs, which is similar to what Angular does - putting test files for components in the same location as the component files.
