GenFu is a library you can use to generate realistic test data. It is composed of several property fillers that can populate commonly named properties through reflection using an internal database of values or randomly created data. You can override any of the fillers, give GenFu hints on how to fill them.
I use big fake data generation very often. The ListOf method uses a regular list and is therefore very memory-hungry.
That's why I added a few methods to generate lazy collections:
I think this could be of use to a lot of developers. I'll be happy for the merge my pull request.
