Add test parallelization to Rails 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.
