Empty spec causes infinite loop hang

[amandapouget]

it('hangs forever and it takes you days to figure out why...', () => {
  // my spec is empty right now, without an 'expect' statement
}

It took me forever to realize that this was the behavior I was observing. I suspected So. Many. Things. in my code before I finally realized that common denominator of when jasmine-rails hangs.
