The order of the tests is arbitrary as there are no dependencies +across the tests. Specifically, every test performs clean-up operations which +return the system to the same state as before the test. + + +Test Descriptions +================= + +---------------------------------------------------------------- +Test Case 1 - vEPC +---------------------------------------------------------------- + +Short name +---------- + +dovetail.vnf.vepc + + +Use case specification +---------------------- + +The Evolved Packet Core (EPC) is the main component of the System Architecture +Evolution (SAE) which forms the core of the 3GPP LTE specification. + +vEPC has been integrated in Functest to demonstrate the capability to deploy +a complex mobility-specific NFV scenario on the OPNFV platform. The OAI EPC +supports most of the essential functions defined by the 3GPP Technical Specs; +hence the successful execution of functional tests on the OAI EPC provides a +good endorsement of the underlying NFV platform. + + +Test preconditions +------------------ + +At least one compute node is available. No further pre-configuration needed. + + +Basic test flow execution description and pass/fail criteria +------------------------------------------------------------ + +Methodology for verifying connectivity +'''''''''''''''''''''''''''''''''''''' + +This integration also includes ABot, a Test Orchestration system that enables +test scenarios to be defined in high-level DSL. ABot is also deployed as a VM +on the OPNFV platform; and this provides an example of the automation driver +and the Test VNF being both deployed as separate VNFs on the underlying OPNFV +platform. + + +Test execution +'''''''''''''' +* Test action 1: Deploy Juju controller (VNF Manager) using Bootstrap command. +* Test action 2: Deploy ABot (Orchestrator) and OAI EPC as Juju charms. + Configuration of ABot and OAI EPC components is handled through built-in Juju + relations. +* Test action 3: Execution of ABot feature files triggered by Juju actions. + This executes a suite of LTE signalling tests on the OAI EPC. +* Test action 4: ABot test results are parsed accordingly. +* Test action 5: The deployed VMS are deleted. + + +Pass / fail criteria +'''''''''''''''''''' + +The VNF Manager (juju) should be deployed successfully + +Test executor (ABot), test Orchestration system is deployed and enables test +scenarios to be defined in high-level DSL + +VMs which are act as VNFs (including the VNF that is the SUT for test case) are +following the 3GPP technical specifications accordingly. + + +Post conditions +--------------- + +The clean-up operations are run. |
