示例1: test_dash_underscore_introspection
# 需要导入模块: from tornado.options import OptionParser [as 别名]
# 或者: from tornado.options.OptionParser import print_help [as 别名]
def test_dash_underscore_introspection(self):
# Original names are preserved in introspection APIs.
options = OptionParser()
options.define('with-dash', group='g')
options.define('with_underscore', group='g')
all_options = ['help', 'with-dash', 'with_underscore']
self.assertEqual(sorted(options), all_options)
self.assertEqual(sorted(k for (k, v) in options.items()), all_options)
self.assertEqual(sorted(options.as_dict().keys()), all_options)
self.assertEqual(sorted(options.group_dict('g')),
['with-dash', 'with_underscore'])
# --help shows CLI-style names with dashes.
buf = StringIO()
options.print_help(buf)
self.assertIn('--with-dash', buf.getvalue())
