Cases and template seem to be very simple, and may be used in documenting this process.

test_case.workload should include the assertion.
So this line can be simplified to: <%= test_case.workload %>

This can be made private as it is only needed by workload

"#{input}"
This will work, but it's a good habit to use input.inspect which will handle input that contains quotes.
Nice usage of %Q though. 👍

I've updated the documentation to help clarify this: #560

Is there a style guide somewhere (other than the README)? Because some of the exercises use work_load and others use workload. In fact, as long as it is the same in both example.tt and <exercise>_cases.rb it should work fine.

No, just the README.
I've made a PR to rename the old occurrences to try and clear this up: #561

Thanks for doing this @hilary ❤️ It will be some non-deterministic amount of time until this change is visible as it requires Katrina to do a release to the live site, but that will probably happen sometime in the next day or two. |
