How to silence Puma for your feature tests

When RSpecs runs the first feature spec, you may see log output like this:

CopyCapybara starting Puma...
* Version 6.5.0, codename: Sky's Version
* Min threads: 0, max threads: 4
* Listening on http://127.0.0.1:39949

You can disable this behavior by tweaking Capybara's Puma server in your spec/support/capybara.rb:

CopyCapybara.server = :puma, { Silent: true }

Note

You don't need to configure this if you're using system tests with modern versions of Rails.
