Maybe some data consistency constraints are preventing you from dropping the client table (eg you have more tables in the schema, but you only loaded the Client table into AR during unit testing). Try to drop all tables in the schema manually before running the test. Hi Stew,

(I'm calling "User" "Client", but otherwise I'm pretty much the same as the examples given.) Here's the error I get when I try to run NUnit for the first time: Scrumpy.Database.Test.Tests.ClientTests.TestAddingUsers: Castle.ActiveRecord.Framework.ActiveRecordException : Could not drop the schema ----> NHibernate.ADOException : Could not close Npgsql.NpgsqlConnection connection ----> System.NotSupportedException : This stream does not support seek operations. TearDown : System.Reflection.TargetInvocationException : Exception has been thrown by the target of an invocation. ----> System.NullReferenceException : Object reference not set to an instance of an object.

It says "password"when it's checking for email. Thanks, Federico Hi,

I think the text in your TestInvalidFormatEmail() is wrong. It says “password”when it’s checking for email.

Thanks,

Federico

You can use NHibernate directly from Castle and use the Repository pattern, for example, to write the code in a way that enables you to test domain code independently of storage. Hi Ulu,

For example, I want to create an entity and verify that my model class fetches (or ignores) it. Or I want to execute a method and verify that an entity object has been created, without a database roundtrip. Hitting a database may be fine when you do integration testing, but I don't want to touch it in _every_ test. If you can suggest another pattern, I'll be happy to try it. Another useful application is when you are pretty sure that you have all relevant objects fetched already and you don't want to fetch them again. I know that ISession is some sot of a cache, but the online documentation on AR cache is "to be added". Could you please pint me in the right direction? Thanks ulu Hi,
