GitHub Flavored Markdown test bed

[joshbruce]

Marked version: 0.3.19

Markdown flavor: GitHub Flavored Markdown

Description

Adds GitHub Flavored Markdown to test bed.

It is our understanding that GFM is basically just CommonMark with some extensions. Therefore, this only adds the extensions to the overarching test suite.

@UziTech: Would also like to start shifting to the separate folders concept but don't know where to begin; think it's just easier to ask and learn or if you would be willing to take it on.

With these additional tests we should have a more trustworthy test bed overall...specifically one that protects itself against regression. Would like to get #1135 using it before merging that in, unless you or @styfle think there's a good reason not to.

LGTM 👍

where are you getting the examples for github_flavored_markdown.json?

[joshbruce]

@UziTech: That one I had to build, unfortunately.

https://github.github.com/gfm/ - I went to each of the TOC links that said "extension" - and copied and pasted (and modified for new lines - didn't see any tabs or anything weird).

Here's the plain text version: https://github.github.com/gfm/spec.txt

You can run this on this, like this, and then filter it in some way.

Could we put this in a /test/specs/gfm folder like:

this will follow the update to the cm tests in #1213

[joshbruce]

Think I got it. A couple of questions for my own edification.

1. What's with the tilde at shouldFail?
2. Should I be using sanitize?

[UziTech]

1. https://stackoverflow.com/a/12299717/806777
2. No, the sanitize set in beforeEach in Test folders #1213 is just to reset the defaults after the original tests. once we merge Reset defaults before tests #1212 it will be removed. I just added it in so the tests would pass.
