* Add option to set parallel test worker count to the physical core count of ↵Bogdan2018-12-181-4/+4
| | | | | | | | | | | | | | | | | | | | | | the machine (#34735) * Add option to set parallel test worker count to the physical core count of the machine Also, use the physical core count of the machine as the default number of workers, and generate the `test_helper.rb` file with `parallelize(workers: :number_of_processors)` Closes #34734 * Ensure that we always test parallel testing Since #34734 we decided to use the physical core count of the machine as the default number of workers in the parallel testing, we need to ensure that some tests use at least 2 workers because we could run those tests on VM that has only 1 physical core. It also fixes tests failures on the CI since Travis server we are using has only one physical core. See https://travis-ci.org/rails/rails/jobs/469281088#L2352

| | | | | | | | | | | | | | | | | | As discussed in #33203 rails command already looks for, and runs, bin/rails if it is present. We were mixing recommendations within guides and USAGE guidelines, in some files we recommended using rails, in others bin/rails and in some cases we even had both options mixed together.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provides both a forked process and threaded parallelization options. To use add `parallelize` to your test suite. Takes a `workers` argument that controls how many times the process is forked. For each process a new database will be created suffixed with the worker number; test-database-0 and test-database-1 respectively. If `ENV["PARALLEL_WORKERS"]` is set the workers argument will be ignored and the environment variable will be used instead. This is useful for CI environments, or other environments where you may need more workers than you do for local testing. If the number of workers is set to `1` or fewer, the tests will not be parallelized. The default parallelization method is to fork processes. If you'd like to use threads instead you can pass `with: :threads` to the `parallelize` method. Note the threaded parallelization does not create multiple database and will not work with system tests at this time. parallelize(workers: 2, with: :threads) The threaded parallelization uses Minitest's parallel exector directly. The processes paralleliztion uses a Ruby Drb server. For parallelization via threads a setup hook and cleanup hook are provided. ``` class ActiveSupport::TestCase parallelize_setup do |worker| # setup databases end parallelize_teardown do |worker| # cleanup database end parallelize(workers: 2) end ``` [Eileen M. Uchitelle, Aaron Patterson]

Additionally the users create view is unlikely to have the text "UserCreates" since that is likely generated as well. This is now an example of visiting the users index.
