Suppress Ruby warnings when running specs

Question

I\'m looking for a way to suppress Ruby warnings when I run my specs.

spec spec/models/account_spec.rb

I receive warnings such as:

Answer 1

Putting Warning[:deprecated] = false after require "rails/all" in config/application.rb works very well to suppress those warnings everywhere. You can do

Warning[:deprecated] = false if Rails.env.test?

for your particular case, or better yet - put it in config/environments/test.rb, but I'm not sure how well it is going to work since I belive some stuff is loaded before that.

Answer 2

You can also use the "RUBYOPT" environment variable to pass -W0 to rspec:

RUBYOPT=W0 rspec spec/models/event_spec.rb

This allows you to run multiple specs by passing in a directory

RUBYOPT=W0 rspec spec/models

Answer 3

The only solution that worked for me is to add $VERBOSE = nil on top of my config/environments/test.rb file

  Rails.application.configure do
   $VERBOSE = nil

I'm with faker warning problems faker-1.9.6/lib/faker/default/number.rb:34. Use it local because it hides all other warnings.

rspec has a tag option you can use -- I simply used /dev/null.

rspec spec --deprecation-out /dev/null
