# This feature spec is intended to be a comprehensive exercising of all of
|
|
|
|
# GitLab's non-standard Markdown parsing and the integration thereof.
|
|
|
|
#
|
|
|
|
# These tests should be very high-level. Anything low-level belongs in the specs
|
|
|
|
# for the corresponding HTML::Pipeline filter or helper method.
|
|
|
|
#
|
|
|
|
# The idea is to pass a Markdown document through our entire processing stack.
|
|
|
|
#
|
|
|
|
# The process looks like this:
|
|
|
|
#
|
|
|
|
# Raw Markdown
|
|
|
|
# -> `markdown` helper
|
|
|
|
# -> Redcarpet::Render::GitlabHTML converts Markdown to HTML
|
|
|
|
# -> Post-process HTML
|
2015-08-12 22:45:16 -04:00
|
|
|
# -> `gfm` helper
|
2015-04-23 00:21:11 -04:00
|
|
|
# -> HTML::Pipeline
|
2015-07-22 21:22:57 -04:00
|
|
|
# -> SanitizationFilter
|
|
|
|
# -> Other filters, depending on pipeline
|
2015-04-23 00:21:11 -04:00
|
|
|
# -> `html_safe`
|
|
|
|
# -> Template
|
|
|
|
#
|
|
|
|
# See the MarkdownFeature class for setup details.
