PathProcessing.Tests.ps1

# These Pester tests are for the for parameter-* and ex-path* snippets.
# Take a look at the .vscode\tasks.json file to see how you can create
# and configure a test task runner that will run all the Pester tests
# in your workspace folder.

# To run these Pester tests, press Ctrl+Shift+T or press Ctrl+Shift+P,
# type "test" and select "Tasks: Run Test Task".  This will invoke the
# test task runner defined in .vscode\tasks.json.

# This (empty) file is required by some of the tests.
