# This file contains a list of discreet tests that can be run against the environment
# Each test named Test-* is exported and discovered to be run by the user-facing function.
# The user uses Include and Exclude parameters to run specific tests. (this provides a consistent experience across validators)
# If tests have dependencies on other tests, or they should be run in a specific order, the pattern describe above should be removed.
