# Ohcount::Test is a base class which includes several helper methods for parser testing.
# All unit tests in Ohcount should derive from this class.
#
# ==== Manual Testing
#
# To manually test a parser, rebuild ohcount and run it against your test file:
#
#   rake
#   bin/ohcount --annotate test/src_dir/my_file.ext
#
# The +annotate+ option will emit your test file to the console, and each line will be
# labeled as code, comment, or blank.
#
class Ohcount::Test < Test::Unit::TestCase

	# For reasons unknown, the base class defines a default_test method to throw a failure.
	# We override it with a no-op to prevent this 'helpful' feature.
	def default_test; end
