I am trying to detect HasManyToMany relationships in entities at run-time for testing purposes. I've had many problems with people writing bad mappings so I wrote a test to test every single mapping on our continuous integration server.

Right now I can test every entity, composite and non-composite by detecting the mapped Id property(s) and calling .Get() or a composite getter. Most of which is done using reflection. I am using GetClassMetadata while going over every entity type.

But I missed testing something that was broken, a HasManyToMany.
I am using Fluent NHibernate, and the mapping is:

```
        mapping.HasManyToMany<ServiceType>(x => x.ServiceTypes)
            .Schema("Marketplace")
            .Table("ListingServiceTypes")
            .ParentKeyColumn("PackageID")
            .ChildKeyColumn("ServiceTypeID")
            .Cascade.SaveUpdate().LazyLoad();

```

Now since there is no entity to "test" this relationship with, I do not run over it.
What I need to know is how can I find the properties of an object that are mapped with "HasManyToMany". I can invoke them just fine, if I could only detect them.

I do not want to have to force lazy loading of every collection because if the mapping for the individual entities are correct, the mappings will be, because we use conventions for them.
