When running tests in Rails, sometimes you need to perform various tasks in the database directly which can lead to a lot of unwanted messages in your test output.

If you’re using Postgresql, simply add the following line to your tests/tests_helper.rb file.

ActiveRecord::Base.connection.execute "set client_min_messages to ERROR"

Now you’ll only see messages of ERROR and above in your test output.

Update

Found a better way to do this. In your database.yml file, simply add the following line to your :test section.

min_messages: ERROR
