Suppress Capybara’s RSpec test output

Do you have a Rails 6 app with RSpec and Capybara and ever wondered how to suppress the message:

.............................Capybara starting Puma…
* Version 3.12.6 , codename: Llamas in Pajamas
* Min threads: 0, max threads: 4
* Listening on tcp://127.0.0.1:61678
.............................

This is because Capybara is starting up Puma.

To get a nice output, simple add the following rule to /spec/rails_helper.rb

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

Now RSpec will suppress the output of Puma.
