Well, I've been getting rid of my Factory Girl for my controllers at least and I run 280 tests in about 1.5 seconds. To me, this is worth it as before it took 40-50 seconds. This is too much of a speed improvement to ignore I think.
I am at a loss as to why Factory_girl takes so many cpu cycles to create a few objects per test. I have benchmarked a simple call to Factory.create(:user), and it takes .14 seconds to run. Even if you use Factory.build() though and it doesn't hit the database, it is STILL slow. I am at a loss as to how factory_girl cannot come close to the performance of manually instantiating the object yourself. Why is it so much slower? I'd have to look at their source code to know for sure. Honestly though, I have removed factory_girl completely from my controller tests and I am so thrilled. I have not really lost anything in terms of expressiveness. Sure, I have to add a pieces of data to make render_views comply, but it's not much. It is a *very small* price to pay for this much performance gain.
