Rails - Populate test database with development data

Is there any trivial way to copy the data from developmenet database into the test one? I know theres a way to copy schema and recreate database, but is there any rake task to populate test database with development one?

From stackoverflow

• You can use:

  rake db:test:clone
  

  To copy the development db into test.

  mdrozdziel : Doesn't work for me at all. Structure is created, but no records are copied. Is that task ment to copy the data at all? The description isn't pointing that directly.

• You can use mysql directly:

  mysqldump app_development | mysql app_test
