rspec using old files when rerunning tests

Question

This is my first project in Rails 4, I'm using 4.2

I'm finding that rspec is not reloading my spec files each time it runs, so tests that I've fixed continue to fail with the old error message.

I'm guessing this has something to do with spring but I can't seem to find information on how to configure paths it should reload.

I'm launching rspec using bin/rspec, and here's my Gemfile if that's of use.
