controllers/external_works_controller currently has 53.66% test coverage on Coveralls:
We'd like better coverage. In particular, the #fetch action needs to be covered.
How to test:
Use Coveralls to confirm that the coverage percentage has increased and the fetch action is covered:
1. Go to https://coveralls.io/github/otwcode/otwarchive?branch=master
2. In the "Search" field near the "Source Files on Master" heading, enter the name of the controller: controllers/external_works_controller.rb
3. Note the number in the "Coverage" column of the table
4. The lines of code making up def fetch should be highlighted in green
