示例1: test_can_connect
# 需要导入模块: from kafka.client_async import KafkaClient [as 别名]
# 或者: from kafka.client_async.KafkaClient import _can_connect [as 别名]
def test_can_connect(conn):
cli = KafkaClient()
# Node is not in broker metadata - cant connect
assert not cli._can_connect(2)
# Node is in broker metadata but not in _conns
assert 0 not in cli._conns
assert cli._can_connect(0)
# Node is connected, can't reconnect
assert cli._maybe_connect(0) is True
assert not cli._can_connect(0)
# Node is disconnected, can connect
cli._conns[0].state = ConnectionStates.DISCONNECTED
assert cli._can_connect(0)
# Node is disconnected, but blacked out
conn.blacked_out.return_value = True
assert not cli._can_connect(0)
