Question

I use this command to run a unit test in rails:

$ ruby -Itest test/unit/post_test.rb

I get an error “Test is not a module (TypeError)” and no tests are run.

Could it be related to the fact that I have a model class named “Test”? If there is no way to make that work, what would be the fastest way to refactor and change the class name?

Answer 1

I believe you’re right that it’s because you’ve created a model using a name you shouldn’t use (Test in this case).

All you should need to do is:

Create a migration to rename the database table: (rename_table :oldname, :newname)

• Rename the model.
• Edit any associations in other models.
• Rename the controller (if required)
• Modify routes.rb
• Modify any links in views.
• Rename views.
• Rename the model in controllers and views.
• Rename and modify any tests.
