+# 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.
