Error with devise

[yovasx2]

I'm using Devise Token Auth gem and, everytime I run my test suite in Rails 4.2.5 app, I'm getting this deprecation warning from Devise:

DEPRECATION WARNING: [Devise] config.email_regexp will have a new default on Devise 4.1 To keep the current behavior please set in your config/initializers/devise.rb the following:

Devise.setup do |config|
   config.email_regexp = /\A[^@\s]+@([^@\s]+\.)+[^@\W]+\z/
end

If you want to use the new default:

Devise.setup do |config|
   config.email_regexp = /\A[^@\s]+@[^@\s]+\z/
end

(called from block in tsort_each at /usr/local/lib/ruby/2.2.0/tsort.rb:226)
I've already added config/initializers/devise.rb file manually and have set email_regex as suggested by the message above, but the annoying message persists.

How can I disable this message?

Not a full fix but this SO answer hid the deprecation warning for me

In fact that's my answer
