How the simples thing (its gem) makes specs much easier to read
# Controller spec using plain old matchers
describe "#create" do
let(:participation) { stub 'Participation' }
let(:params) { {:participation => {}} }
before { InviteUser.stub(:into_company_by_params => participation) }
context "with success" do
before { participation.stub(:valid? => true) }

Run Postgres Specs in Ramdisk
  • This creates a 560mb ramdisk. Adjust the size accordingly. I think the number at the end of the command is the number of disk blocks. They are 2kb in size for me.
  • Restarting postgres is not necessary; you can create the ramdisk and tablespace while postgres is running.
  • You will lose all data in the ramdisk tablespace when you shut your machine down

  $ diskutil erasevolume HFS+ "postgres_ramdisk" `hdiutil attach -nomount ram://1165430`
  Started erase on disk1
  Unmounting disk
  Erasing
 Initialized /dev/rdisk1 as a 569 MB HFS Plus volume
