Rails + Rake: How to simulate running of rake task to see if it works?

Question

Is there a way to do a test run of a rake task? If so what is the command to do it? I don't want to actually touch the development database since my task manipulates the data.

Answer 1

Yes you can actually run bundle exec rake COMMAND -n

Having a look at rakes help we can see it here.

# rake --help
--dry-run Do a dry run without executing actions.
