-If `parallelism` is set to N > 1, then N independent executors will be set up and each will run the steps of that job in parallel. This can help optimize your test steps; you can split your test suite, using the CircleCI CLI, across parallel containers so the job will complete in a shorter time. Certain parallelism-aware steps can opt out of the parallelism and only run on a single executor (for example [`deploy` step](#deploy)).
