Is there a way to manually clear the pester TestDrive, other than something like Remove-Item "TestDrive:\" -Recurse -Force
AFAIK there isn't a function to trigger a clear of TestDrive, so yes I would recommend using something like Remove-Item $TestDrive -Recurse -Force
if you had a specific need to.
However you should also be aware that a TestDrive is scoped to a Describe
or Context
block and automatically cleaned up at the end of those blocks. So if you want to avoid conflicts between different usages of TestDrive just have those test in different Context blocks.
