示例1: test_get_head_node
# 需要导入模块: from appscale.tools.appscale import AppScale [as 别名]
# 或者: from appscale.tools.appscale.AppScale import get_head_node [as 别名]
def test_get_head_node(self):
shadow_node_1 = {'public_ip': 'public2', 'roles': ['shadow']}
appengine_node = {'public_ip': 'public1', 'roles': ['appengine']}

appscale = AppScale()
# If the list of nodes does not have a node with the shadow role, the
# tools should raise an AppScaleException.
with self.assertRaises(AppScaleException):
appscale.get_head_node([appengine_node])
# If the list of nodes contains any nodes with the shadow role, the tools
# should return the public IP address of the first node which has that
# role.
self.assertEqual(shadow_node_1['public_ip'],
appscale.get_head_node([shadow_node_1, appengine_node, shadow_node_2]))
