Whenever I try to run my rspec tests (using 'rspec spec' or 'bundle exec rspec spec') I get a huge amount of output on the screen. It seems to be going through every gem in my Gemfile and displaying messages from it. Below is a sample of that output (there was much much more).
Can someone tell me what these messages are and how to stop them from showing every time I want to run tests?

See https://github.com/rspec/rspec-core/issues/1571. Basically, recent rspec versions added --warnings to the .rspec file by default. This has led to lots of warnings about code in gems being output. The 'fix' for now is to remove the --warnings line.
