为什么murano-test-runner连接到keystone？

Question

我在Tomcat包之后为我的包"kubernetes-cluster“添加了一些单元测试(参见：https://github.com/openstack/murano-apps/blob/master/Tomcat/package/Classes/TomcatTest.yaml)。

然后，使用命令运行它(不带--config-file、--os-auth-url，在path /etc/murano/中不带murano.conf )：

murano-test-runner -v io.murano.apps.docker.kubernetes.KuryrCluster io.murano.test.KuryrClusterTest -l /my-packages and core-library/local/path

我得到了错误消息：

我只想检查我的单元测试是否像pep8或py27那样用muranoPL编写正确。我可以像tox -e py27一样运行tox -e murano-test-runner而不需要连接keystone服务器和neutron服务器吗？如果不能，原因何在？如果我可以，怎么做？模拟键控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(and deal with auth_uri.replace('v2.0', 'v3') AttributeError Exception) murano.engine.system.net_explorer.NetworkExplorer._get_client

则murano-test-runner可以在没有config-opts os-*或config-file的情况下运行
