test-unit-activesupport doesn't support parallelize yet #13

Open hiroyuki-sato opened 3 years ago

hiroyuki-sato commented 3 years ago

Rails6 introduced parallel methods

rails new command generates the following contents in test/test_helper.rb

class ActiveSupport::TestCase
  # Run tests in parallel with specified workers
  parallelize(workers: :number_of_processors)

  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...
end

After test-unit setting, I execute rails test command and I got the following error.

Workaround

comment(or remove) parallelize part

class ActiveSupport::TestCase
  # Run tests in parallel with specified workers
  #parallelize(workers: :number_of_processors) # <--- HERE

  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...
end

Wow. I didn't know it.

We need to add support for parallelization to test-unit.
