Support for the Ruby 2.4 series has ended. See here for reference.
Test case for creating new plain-text RDoc::Markup formatters.  See also RDoc::Markup::FormatterTestCase
See test_rdoc_markup_to_rdoc.rb for a complete example.
Example:
class TestRDocMarkupToNewTextFormat < RDoc::Markup::TextFormatterTestCase add_visitor_tests add_text_tests def setup super @to = RDoc::Markup::ToNewTextFormat.new end def accept_blank_line assert_equal :junk, @to.res.join end # ... end
Adds test cases to the calling TestCase.
