# for convenience just run the passed file when we invoke this via launchConfig.json when
# the file is a non-test file
$isDirectory = (Get-Item $Path).PSIsContainer
$isTestFile = $Path.EndsWith($Configuration.Run.TestExtension.Value)
if (-not $isDirectory -and -not $isTestFile) {

Invoke-Pester -Configuration $Configuration

Will prob work better as I see an odd issue where I end up with $path being a path as a string, and then times an object with a path with a property and then EndsWith isn't a valid method when its a null value. I just haven't quite got to the bottom of it.
