Running migration script on test environment only

Question

Is there a way to only run migrations in the test environment?

I'd like to create tables and seed the data in only the test environment since the staging and production databases already exist.

Answer 1

I've found a solution based on the post here. This allows me to only apply the migration against the test environment.

class CreateLicenseDatabase < ActiveRecord::Migration
  def change
    if Rails.env.test?

      create_table.....

    end
  end
end

Answer 2

Can't you just do this:

RAILS_ENV=test rake db:create
RAILS_ENV=test rake db:migrate

?
