How to use this with IOC , UnitOfwork and test unit ?

[rluisnpt1]

This implementation is very good, however i have one point of situation because how make this when i use Unitofwork and Ioc and unit test, like this project for example http://www.bomboca.co.uk/umbraco-cms/unit-testing-umbraco/ and this is a project him https://s3-eu-west-1.amazonaws.com/bomboca-promo/Bomboca.Marketing.zip ? The my it is a little diferente because i use another project to separe the structure Umbraco of business Layers. I don't understand one thing because you use modelsBulder umbraco and I use vega.USiteBuilder as the exemple i said before.
