Up until now I've been deploying Rails apps to our Apache/Passenger setup using a simple Rake task that I wrote. I haven't tried to mess around with Capistrano or Vlad the Deployer.
However, now more developers are coming on board, and I'm interesting in arranging things so that the deployment process runs the tests first and won't deploy unless they all pass. So I'm revisiting the question.
It's been a while since I looked into this. What are most people doing these days? Still using Capistrano? Writing individual Rake tasks? Something else?
