+  @brief Testing mm_assigndirectlib macro
+  @details  A valid library must first be configured in metadata.
+  To test success, also define a table for which we can test the existence.
+  This is a unit test - not part of the full test run, as it would be a
+  lot of overhead to create an external DB and metadata setup each time.
