T.delay(arg, kwarg=value)
#always a shortcut to .apply_async.

T.apply_async((arg, ), {'kwarg': value})

T.apply_async(countdown=10)
#executes 10 seconds from now.

expect(x).toEqual(y); compares objects or primitives x and y and passes if they are equivalent

expect(x).toBe(y); compares objects or primitives x and y and passes if they are the same object

expect(x).toMatch(pattern); compares x to string or regular expression pattern and passes if they match

expect(x).toBeDefined(); passes if x is not undefined

expect(x).toBeUndefined(); passes if x is undefined

# Start/Stop PostgreSQL

If this is your first install, automatically load on login with:
  mkdir -p ~/Library/LaunchAgents
  cp /usr/local/Cellar/postgresql/9.1.3/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/
  launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

If this is an upgrade and you already have the homebrew.mxcl.postgresql.plist loaded:
  launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
  cp /usr/local/Cellar/postgresql/9.1.3/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/
