(c) OPNFV, Huawei ================= Testing ecosystem ================= Testing is a key area and also a challenge for OPNFV in order to be able to verify and validate the platform we are creating. This is a complex task as we have to test the integration of the components, the functionality we are creating and using and we have to verify that the platform is suitable for telecom applications. We do testing in an automated fashion by using several test tools and frameworks in our CI/CD pipeline. This chapter gives an overview about our testing tools and activities. Release verification ==================== OPNFV releases the target platform together with the deployment tools in a set of scenarios that provides choices regarding the deployed components and the available features. The scenarios and the provided functionality are tested automatically in the CI/CD pipeline mentioned above and they are considered to be ready for release after at least 4 successful consecutive iterations. The functional testing and the platform validation are divided between two projects called Functest and Yardstick. Functest -------- Functest provides a functional testing framework along with a set of test suites and test cases that test and verify OPNFV platform functionality. The scope of Functest and relevant test cases can be found in its `user guide `_. In Brahmaputra, Functest is focusing on OpenStack and SDN controllers deployment testing. Its testing framework combines a number of testing tools to verify the key components of the OPNFV platform are running successfully. For example, Rally and Tempest are integrated for OpenStack basic functional testing and benchmark, Robot is used for ODL testing, and Teston is integrated for ONOS testing. Besides these, Functest also includes tests by deploying candidate VNFs such as vPing and vIMS, and testing their basic functionality. Yardstick --------- Yardstick is a testing project for verifying the infrastructure compliance when running VNF applications. Yardstick can benchmark a number of characteristics/performance vectors about the infrastructure, that makes it become a useful pre-deployment NFVI testing tools. Yardstick is also a flexible testing framework supporting OPNFV feature testing by the various projects in OPNFV. Projects can plug in their test cases for specific features easily. The detail of Yardstick project can be found in the `yardstick user guide `_. There are two types of test cases in Yardstick: Yardstick generic test cases and OPNFV feature test cases. Yardstick generic test cases include basic characteristics benchmarking in compute/storage/network area. OPNFV feature test cases include basic telecom feature testing from OPNFV projects, for example nfv-kvm, sfc, ipv6, Parser, Availability and SDN VPN. All of the Yardstick test cases are listed on ``_. Additional Testing ================== Besides the test suites and cases for release verification, there are some additional testing for specific feature or characteristics on OPNFV platform. These testing framework and test cases may include some specific needs, such as extended measurements, or additional testing stimuli, or tests which cause disturbances on the environment. These additional testing can provide a more complete evaluation about OPNFV platform deployment. Qtip ---- Qtip is a performance benchmark testing project by using a "Bottom-Up" approach in characterizing and benchmarking OPNFV platform. Qtip aims to benchmark the performance of components for a quantitative analysis and doesn't deal with validation of the platform. In Brahmaputra, Qtip develops a flexible framework, adds a number of test cases covering compute/storage/network area, and compares these benchmarks on a bare metal machine vs a VM. These contrastive result can be used to evaluate the performance of these components on the OPNFV platform basically. VSPERF ------ VSPERF will develop a generic and architecture agnostic vSwitch testing framework and associated tests, that will serve as a basis for validating the suitability of different vSwitch implementations in a Telco NFV deployment environment. The output of this project will be utilized as part of OPNFV Platform and VNF level testing and validation. Bottlenecks ----------- Bottlenecks will provide a framework to find system bottlenecks by testing and verifying OPNFV infrastructure in a staging environment before committing it to a production environment. The Bottlenecks framework can not only find specific system limitations and bottlenecks, but also the root cause of these bottlenecks. In Brahmaputra, Bottlenecks includes two test cases: rubbos and vstf. These test cases are executed on OPNFV community pods, and test result report are visible on the community testing dashboard. ..
