Changes to Luhn tests

[IanWhitney]

We recently rewrote the test suite for the Luhn exercise. Since this track implements Luhn, please take a look at the new canonical_data.json file and see if your track should update its implementation or tests.

Details on the test changes and the motivation can be found in the PR.

Tracking of these changes is being done at the tracking issue.

Now is a good time to do a generator for this exercise/test as well.

@IanWhitney @kotp is there anything that needs to be done for this track?

[kotp]

@morme Yes.

Look through the issues and if you see something you are interested in, let me know. I do monitor the Exercism gitter rooms, and contacting me for Ruby in the ruby gitter room is a good place to do so if you do have questions specifically, or if you would like to have some help setting up and working on an issue.

If you are interested in working on this one specifically, there are two directions that this can go. Either match up the current tests with the canonical_data file mentioned in the description above, or work on creating a generator library for this exercise specifically.

The generator is the long term preferred solution.

@kotp i'd like to know more about the generator option.

[kotp]

This document is a good place to start. You can also look at the lib/ folder to see the exercises that are already generated, and compare them for examples.

Thanks @hilary !!

[kotp]

Thanks @morme for considering to work on this as well. Hopefully I have not missed your contribution.

[morrme]

@kotp this was one i fought with a little. i still want to get this workflow down, because it would be good to do it on other exercises.

[hilary]

@morrme We updated the documentation for the generators; it was a bit ... obscure :D

[morrme]

@hilary i blamed my inexperience. good to know!

[Insti]

Definitely not your fault @morrme.
