我为我的软件包“kubernetes-cluster”添加一些单元测试，遵循Tomcat包（请参阅：https://github.com/openstack/murano-apps/blob/master/Tomcat/package/Classes/TomcatTest.yaml）。为什么murano-test-runner与keystone连接？
，然后用命令来运行它（无--config文件， - OS-AUTH-URL，没有路径的/ etc /穆拉诺/ 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写在muranoPL权利或不，像pep8或py27。 我可以运行tox -e murano-test-runner像tox -e py27而不连接到keystone服务器和neutron服务器吗？如果不能，为什么？如果可以的话，怎么样？模拟keystoneclient和neutronclient？或其他方式？ 有人可以帮助我吗？谢谢。
