Add additional test tasks in Rails 5

Question

In rails 4.x you used to be able to easily add additional Rails::TestTasks that would run alongside the core Rails app tests during rake test. For instance, like this:

In Rails 5, none of the approaches I've seen seem to work, and while it seems to be documented/understood around the internet that they no longer work, I haven't seen any mention of the new way to do things.

Anybody know?

It still works but changed in Rails 5.1.3.
Basically rails test runner now picks up everything matching test/**/*_test.rb except files matching test/system/**/*_test.rb so you may not have to do anything if your tests are already within test folder.

You can still setup specific test task under test/ like this:

namespace :test do
  %w[queries reporters services workers].each do |name|
    task name => 'test:prepare' do
      $LOAD_PATH << 'test'
      Rails::TestUnit::Runner.rake_run(["test/#{name}"])
    end
  end
end
