--dry-run Execute the migration as a dry run

Question

Can anyone tell the meaning of "dry run" in Doctrine 2? I am not able to find it on Google.

I can only get some information by using this command

php app/console doctrine:migrations:migrate --help

which outputs

--dry-run Execute the migration as a dry run.

Answer 1

Dry run in the context of an console command means to run all actions for gathering informations, you get all verbose output, which will be executed, but nothing is really executed. So you can see, what the command will do, but can be safe, your database won't be modified.
