SimpleCov only reports the last controller test and sets to 0.0% all previous results

[OfficeYAportatil]

Hi there!!!

I have de following issues.

My Settings:

Gemfile

ruby (3.2.2)
rails (7.0.7)
simplecov (0.22.0) # in test group

test_helper.rb

require 'simplecov
SimpleCov.start 'rails' do
    merge_timeout 2_678_400 # one month for merging 
end

ENV['RAILS_ENV'] ||= 'test'

require_relative '../config/environment'
require 'minitest/sound'
require 'rails/test_help'

Dir[Rails.root.join('test/shared_tests/**/*')].each { |f| require f }
Minitest::Sound.success = "__MINE/fx/ok_#{rand(6)}.mp3"
Minitest::Sound.failure = "__MINE/fx/er_#{rand(6)}.mp3"

module ActiveSupport
  class TestCase
    parallelize(workers: :number_of_processors)
    fixtures :all
    Faker::Config.locale = :es
    Faker::Config.random = Random.new
  end
end

Issues:

Issue #1: All controllers got a 0% when running all tests

• When I run rails test test/controllers/ all the controllers got an 0%
• If I run rails test test/models/, the models are correctly scored
• If I run rails test test/system/, everything got correctly scored

Issue #2: Everything goes back to 0% with the next tests

If after rails test test/system/, I run rails test test/controllers/banks_controller_test.rb, the previous results are forgotten and I everything got scored with 0%. In the Controllers TAB only the tests for banks_controller, concerns/common_controller and application_controller got a score.

Then, if I run a new test, like rails test test/controllers/customers_controller_test.rb, everything keeps its 0% and in the Controllers TAB only the tests for customers_controller, concerns/common_controller and application_controller got a score forgetting the previos score for banks_controller

Hmm, possible this is (or is related to) what I mentioned here: #1074 (comment)

EDIT: My issue was Rails test parallelization. Fix here: #718 (comment)
