SimpleCov Code Coverage Maintenance

[nicholaspneu]

SimpleCov facilities in minitest_helper.rb are broken, particularly when running test:parallel_run_all_tests_locally in Rake. This is mostly due to the ParallelTests class clobbering the class with the same name in the parallel_tests gem which stops it from running. Refer to the full traceback below for the error:

/workspaces/openstudio-standards/vendor/bundle/ruby/3.2.0/gems/simplecov-0.22.0/lib/simplecov.rb:279:in `wait_for_other_processes': undefined method `wait_for_other_processes_to_finish' for ParallelTests:Class (NoMethodError)

      ParallelTests.wait_for_other_processes_to_finish

Fixed this in the fix-simplecov branch by simply renaming occurences of the ParallelTests class to ParallelTestHelper. Will be merged into nrcan, but also noted here for future reference since it concerns the whole repository.
