🎩 What? Why?

There is a somewhat concurrent timeout error in the system specs that test the views with iframes.

The issue seems to relate to puma server threads in the Capybara server configuration.

The issue seems to be resolved when we set the minimum and maximum threads to 1.

Here is information about configuring the puma threads:
https://github.com/puma/puma#thread-pool

Example test run that timed out:

Testing

This seems to happen quite constantly when running the admin newsletter templates system spec, so try try running:

$ cd decidim-admin
$ bundle exec rspec spec/system/admin_manages_newsletter_templates_spec.rb
