Assume I have a variable $ConfigPath in mymodule.psm1 and cmdlet Get-MyConfig uses that variable to fetch the data from the configuration file.

Can I run a test and override that variable so I that I perform the operations on a test file instead of the real configuration file that could affect the software it is used by?

& (gmo modulename) { $configpath = 'x' }

void summit ```ps1 & (gmo modulename) { $configpath = 'x' } ```

Could you please explain a bit what's happening here? I might be missing some knowledge about modules

It runs the scriptblock in the modules state. It allows you to modify variables among other things.
