IMO, it's a bad idea to use a mock database for unit testing. Test using a
database of the same type and schema as your production database. Only
mock what you must (e.g. 3rd party code you don't control), or you run the
risk of production failures even when the related code passes tests.
If you want to do this anyway, you can use the schema_caching extension,
dump the schema cache in production to a file, and load it in testing right
after creating the mock database connection.
Thanks,
