gitlab-org--gitlab-foss/spec/support/markdown_feature.rb

# This is a helper class used by the GitLab Markdown feature spec
#
# Because the feature spec only cares about the output of the Markdown, and the
# test setup and teardown and parsing is fairly expensive, we only want to do it
# once. Unfortunately RSpec will not let you access `let`s in a `before(:all)`
# block, so we fake it by encapsulating all the shared setup in this class.
#
# The class renders `spec/fixtures/markdown.md.erb` using ERB, allowing for
# reference to the factory-created objects.
