How to create dummy fields I use Drupal7. I want to create some dozens of dummy fields in my test node quickly. But, it will take long if I do at "manage fields page"(admin/structure/types/manage/CONTENT_TYPE).

Unfortunately, I couldn't find any modules to do it(Devel Generat can create contents, but not fields). Any suggestions to do it?
Thank you.
You could use this module:
https://www.drupal.org/project/bundle_copy


Create a field
Export the bundle/content type
Copy the field in the exported text, paste several times, changing stuff for each field that you want to change for each new field
Import the same bundle/content type
