One working CAT test that should become one test per table, partition, customer, contract or any family a query can list: a template with a `Metadata` query, expanded into one test per row when the project opens, with `%COLUMN%` placeholders in every property. Obligatory reading before writing a test with a `Metadata` property, before copying a test many times with small changes, and when a project's test count is not what its file suggests.
