Guard with RSpec on Rails 4 giving a lot of warnings

Question

I'm wondering how I can turn off all these warnings when running a simple test:

[1] guard(main)>

I'm running Rails 4.1.1, Ruby 2.1.2p95, and...

guard (2.6.1)
rspec (3.0.0)
guard-rspec (4.2.9)

I've tried running guard with:

guard :rspec, cmd:"ruby -W0 bin/rspec" do

instead of:

guard :rspec, cmd:"spring rspec" do

But it didn't do anything.

These warnings are super annoying, and I'm pretty sure I'm not causing them. Help!

Solution 1

The rspec generator rails generate rspec:install now puts the --warnings option in the .rspec file by default. Remove that line, and the warnings will go away.

Solution 2

You can set the warnings to false in the your test environment to force Rspec to disable the warnings messages.

# spec/spec_helper.rb

config.warnings = false
