The document introduces Test Driven Development (TDD), Continuous Integration (CI), Inversion of Control (IoC), and Aspect Oriented Programming (AOP). It discusses TDD principles and tools for writing tests first before code. CI aims to integrate code changes frequently to prevent integration problems. IoC and dependency injection improve software design by reducing coupling between components. AOP allows cross-cutting concerns like logging to be coded separately from the main program logic.

5. Some Examples namespace ERP.UnitTests.Repository.NHibernate { [ TestFixture ] public class FixtureNHibernateClientRepository { [ SetUp ] public void SetupMethod()‏ { TestUtilities obj= new TestUtilities (); obj.ExecuteQuery( "DELETE FROM CLIENTS" ); obj.ExecuteQuery( @"DBCC CHECKIDENT(Clients,RESEED,0)" ); } [ Test ] public void SaveClient()‏ { Client obj= new Client (); obj.NameSurname = "name" ; obj.City = "city" ; obj.Address = "Address" ; ERP.Repository.NHibernate. ClientRepository objRep= new ClientRepository (); objRep.Save(obj); objRep.Commit(); Client tmp = objRep.Load(1); Assert .AreEqual( true , CompareClients(tmp, obj)); } private bool CompareClients( Client tmp, Client obj)‏ { if (tmp.ID == obj.ID && obj.City == tmp.City && tmp.NameSurname == obj.NameSurname && tmp.Address == obj.Address)‏ return true ; return false ; } } }
