示例1: test_multi_exceptions
# 需要导入模块: from tornado import gen [as 别名]
# 或者: from tornado.gen import Multi [as 别名]
def test_multi_exceptions(self):
with ExpectLog(app_log, "Multiple exceptions in yield list"):
with self.assertRaises(RuntimeError) as cm:
yield gen.Multi([self.async_exception(RuntimeError("error 1")),
self.async_exception(RuntimeError("error 2"))])
self.assertEqual(str(cm.exception), "error 1")
# With only one exception, no error is logged.
with self.assertRaises(RuntimeError):
yield gen.Multi([self.async_exception(RuntimeError("error 1")),
self.async_future(2)])
# Exception logging may be explicitly quieted.

示例2: test_multi_dict
# 需要导入模块: from tornado import gen [as 别名]
# 或者: from tornado.gen import Multi [as 别名]

self.run_gen(f)
# The following tests explicitly run with both gen.Multi
# and gen.multi_future (Task returns a Future, so it can be used
# with either).
