Testing nHibernate mappings

I have just started a new project using nHibernate and Fluent for mapping. The architect has sent me a database from which I have generated several hundred entity classes and the corresponding Fluent mapping files. I know this is not the ideal DDD way of doing things but life is rarely ideal.

What I want to do is test that all the mappings are correct, columns mapped correct, OneToMany, ManyToMany etc. Is there some automated or easy way to do this? I have considered just writing a simple repository that loads a record from every entity and make sure no exception is raised, but most of the tables have no data in them yet.

Solution

Have a look at the PersistenceSpecification in Fluent NHibernate. It's hardly perfect, but it handles a lot of simple cases well.
