Unit testing 为什么murano测试运行程序连接到keystone？

我在Tomcat包之后为我的包“kubernetes集群”添加了一些单元测试（请参阅：）

然后，使用命令运行它（不带--config文件，-os auth url，不带路径/etc/murano/中的murano.conf）：

我收到了错误消息：

我只想检查我的单元测试是否正确使用Muranop编写，比如pep8或py27。 在不连接keystone服务器和Neutrono服务器的情况下，我是否可以像运行

tox-e murano测试运行程序那样运行
tox-e py27
？如果不能，原因为何？如果可以，怎么做？模拟密钥客户端和中性客户端？还是其他方式？
有人能帮我吗？谢谢。
我嘲笑：

keystoneclient.v3.Client（并处理auth_uri.replace（'v2.0'，'v3'）AttributeError异常）
murano.engine.system.net\u explorer.NetworkExplorer.\u get\u client

然后，murano测试运行程序可以在没有配置选项os-*或配置文件的情况下运行
