how do i implement / build / create an 'in memory database' for my unit test
- by Michel
Hi all,
i've started unit testing a while ago and as turned out i did more regression testing than unit testing because i also included my database layer thus going to the database verytime.
So, implemented Unity to inject a fake database layer, but i of course want to store some data, and the main opinion was: "create an in-memory database"
But what is that / how do i implement that?
Main question is: i think i have to fake the database layer, but doesn't that make me create a 'simple database' myself or: how can i keep it simple and not rebuilding Sql Server just for my unit tests :)
At the end of this question i'll give an explanation of the situation i got in on the project i just started on, and i was wondering if this was the way to go.

Current situation i've seen at this client is that testdata is contained in XML files, and there is a 'fake' database layer that connects all the xml files together.
For the real database we're using the entity framework, and this works very simple.
And now, in the 'fake' layer, i have top create all kind of classes to load, save, persist etc. the data.
It sounds weird that there is so much work in the fake layer, and so little in the real layer.
I hope this all makes sense :)
