+# Below are some example test cases. You may uncomment and modify them to match
+# your needs. Notice that they all expect the base error class of `StandardError`.
+# This is because the autogenerated function uses an untyped array for parameters
+# and relies on your implementation to do the validation. As you convert your
+# function to proper dispatches and typed signatures, you should change the
+# expected error of the argument validation examples to `ArgumentError`.
+#
+# Other error types you might encounter include
+#
+# * StandardError
+# * ArgumentError
+# * Puppet::ParseError
