scrabble-score: add tests for optional extensions? (:double/:triple letter values)

[juleskers]

In the scrabble-score exercise, there is the optional section to implement the double-letter-value mechanism. However, there are no tests to guide one when doing this.

I stumbled over this while implementing scrabble-score for the rust-track.
My pull-request against xrust was redirected here for broader discussion.

Should we add tests for this optional section? Or are those intentionally not included to encourage the exerciser to try his/her hand at test-writing?

Should we add tests for this optional section?

No

I also wrote about this here: #512 (comment)

The main problem that should be well described and covered by the canonical-data tests is just the word scoring.

The discussion about how to implement the extensions is part of the extended work and should not be specified in the problem description.

Thanks for the feedback! I'll stop work in that direction then.
