Machinist vs FactoryGirl - pros and cons

Question

I'm working with factory_girl, but looking at the machinist gem. Could you tell me please - what are the pros and cons of migrating to machinist? Have you compared those libs?

Answer 1

Machinist was actually heavily inspired by factory_girl , but varied because machinist's author wanted a different syntax. Since then, factory_girl added different syntax layers to simulate other factory libraries (including machinist's "blueprint" syntax). In other words, both are extremely similar, just with a different default syntax. Personally, I use factory_girl.

Answer 2

Actually, Machinist has a big advantage over Factory Girl: it doesn't hit the DB for associated objects. Look here:

Still not sure about how Machinist handles this, but anyhow it could be a huge performance boost for your test base.

Answer 3

我之前没有使用机械师，但我可以说factory_girl非常容易使用，扩展和撕掉任何类型的项目必须使用的以导轨为中心的东西。
