# RDoc::TestCase is an abstract TestCase to provide common setup and teardown
# across all RDoc tests.  The test case uses minitest, so all the assertions
# of minitest may be used.
#
# The testcase provides the following:
#
# * A reset code-object tree
# * A reset markup preprocessor (RDoc::Markup::PreProcess)
# * The <code>@RM</code> alias of RDoc::Markup (for less typing)
# * <code>@pwd</code> containing the current working directory
# * FileUtils, pp, Tempfile, Dir.tmpdir and StringIO
