+|-----------------------|---------------------------------------------------|
+| prepare()             | prepare VNF env (user, tenant, security group,..) |
+| run(**kwargs)         | run VNF test case                                 |
+| deploy_orchestrator() | deploy cloudify, ONAP, OpenBaton,... (optional)   |
+| deploy_vnf()          | deploy the VNF                                    |
+| test_vnf()            | run tests on the VNF                              |
+
+
+### run(**kwargs)
+
+- deploys an orchestrator if needed (e.g. heat, OpenBaton, Cloudify, ONAP, Juju)
+- deploys the VNF
+- performs tests on the VNF
+
+
+### prepare()
+
+- creates a user
+- creates a Tenant/Project
+- allocates admin role to the user on this tenant
+
+
+### deploy_orchestrator()
+
+- deploys an orchestrator (optional)
+- if this function is overridden then raise orchestratorDeploymentException if error during orchestrator deployment
+
+
+### deploy_vnf()
+
+- **MUST be implemented** by vnf test cases. The details section MAY be updated in the vnf test cases.
+- The deployment can be executed via a specific orchestrator or using build-in orchestrators such as heat, openbaton, cloudify, juju, ONAP, ...
+- returns:
+  True if the VNF is properly deployed
+  False if the VNF is not deployed
+- raises VnfDeploymentException if error during VNF deployment
+
+
+### test_vnf()
+
+- **MUST be implemented** by vnf test cases. The details section MAY be updated in the vnf test cases.
+- Once a VNF is deployed, it is assumed that specific test suite can be run to validate the VNF.
+- returns:
+  True if VNF tests are PASS
+  False if test suite is FAIL
+- raises VnfTestException if error during VNF tests
