Test projects fulfill different roles such as +verifying VIM functionality, benchmarking components and platforms or analysis of measured +KPIs for the scenarios released in OPNFV. + +Feature projects also provide their own test suites that either run independently or within a +test project. + +This document details the OPNFV testing ecosystem, describes common test components used +by individual OPNFV projects and provides links to project specific documentation. + + +OPNFV testing ecosystem +======================= + +The testing projects +-------------------- + +The OPNFV testing projects may be summarized as follows: + +.. figure:: ../../images/OPNFV_testing_working_group.png + :align: center + :alt: Overview of OPNFV Testing projects + +The major testing projects are described in the table below: + ++----------------+---------------------------------------------------------+ +| Project | Description | ++================+=========================================================+ +| Bottlenecks | This project aims to find system bottlenecks by testing | +| | and verifying OPNFV infrastructure in a staging | +| | environment before committing it to a production | +| | environment. Instead of debugging a deployment in | +| | production environment, an automatic method for | +| | executing benchmarks which plans to validate the | +| | deployment during staging is adopted. This project | +| | forms a staging framework to find bottlenecks and to do | +| | analysis of the OPNFV infrastructure. | ++----------------+---------------------------------------------------------+ +| CPerf | SDN Controller benchmarks and performance testing, | +| | applicable to controllers in general. Collaboration of | +| | upstream controller testing experts, external test tool | +| | developers and the standards community. Primarily | +| | contribute to upstream/external tooling, then add jobs | +| | to run those tools on OPNFV's infrastructure. | ++----------------+---------------------------------------------------------+ +| Dovetail | This project intends to define and provide a set of | +| | OPNFV related validation criteria that will provide | +| | input for the evaluation of the use of OPNFV trademarks.| +| | The dovetail project is executed with the guidance and | +| | oversight of the Compliance and Certification committee | +| | and work to secure the goals of the C&C committee for | +| | each release. The project intends to incrementally | +| | define qualification criteria that establish the | +| | foundations of how we are able to measure the ability to| +| | utilize the OPNFV platform, how the platform itself | +| | should behave, and how applications may be deployed on | +| | the platform. | ++----------------+---------------------------------------------------------+ +| Functest | This project deals with the functional testing of the | +| | VIM and NFVI. It leverages several upstream test suites | +| | (OpenStack, ODL, ONOS, etc.) and can be used by feature | +| | project to launch feature test suites in CI/CD. | +| | The project is used for scenario validation. | ++----------------+---------------------------------------------------------+ +| Qtip | QTIP as the project for "Platform Performance | +| | Benchmarking" in OPNFV aims to provide user a simple | +| | indicator for performance, supported by comprehensive | +| | testing data and transparent calculation formula. | +| | It provides a platform with common services for | +| | performance benchmarking which helps users to build | +| | indicators by themselves with ease. | ++----------------+---------------------------------------------------------+ +| Storperf | The purpose of this project is to provide a tool to | +| | measure block and object storage performance in an NFVI.| +| | When complemented with a characterization of typical VF | +| | storage performance requirements, it can provide | +| | pass/fail thresholds for test, staging, and production | +| | NFVI environments. | ++----------------+---------------------------------------------------------+ +| VSperf | This project provides a framework for automation of NFV | +| | data-plane performance testing and benchmarking. The | +| | NFVI fast-path includes switch technology and network | +| | with physical and virtual interfaces. VSperf can be | +| | used to evaluate the suitability of different Switch | +| | implementations and features, quantify data-path | +| | performance and optimize platform configurations. | ++----------------+---------------------------------------------------------+ +| Yardstick | The goal of the Project is to verify the infrastructure | +| | compliance when running VNF applications. NFV Use Cases | +| | described in ETSI GS NFV 001 show a large variety of | +| | applications, each defining specific requirements and | +| | complex configuration on the underlying infrastructure | +| | and test tools.The Yardstick concept decomposes typical | +| | VNF work-load performance metrics into a number of | +| | characteristics/performance vectors, which each of them | +| | can be represented by distinct test-cases. | ++----------------+---------------------------------------------------------+ + + +=================================== +The testing working group resources +=================================== + +The assets +========== + +Overall Architecture +-------------------- +The Test result management can be summarized as follows:: + + +-------------+ +-------------+ +-------------+ + | | | | | | + | Test | | Test | | Test | + | Project #1 | | Project #2 | | Project #N | + | | | | | | + +-------------+ +-------------+ +-------------+ + | | | + V V V + +---------------------------------------------+ + | | + | Test Rest API front end | + | http://testresults.opnfv.org/test | + | | + +---------------------------------------------+ + ^ | ^ + | V | + | +-------------------------+ | + | | | | + | | Test Results DB | | + | | Mongo DB | | + | | | | + | +-------------------------+ | + | | + | | + +----------------------+ +----------------------+ + | | | | + | Testing Dashboards | | Landing page | + | | | | + +----------------------+ +----------------------+ + + +The testing databases +--------------------- +A Mongo DB Database has been introduced for the Brahmaputra release. +The following collections are declared in this database: + * pods: the list of pods used for production CI + * projects: the list of projects providing test cases + * testcases: the test cases related to a given project + * results: the results of the test cases + * scenarios: the OPNFV scenarios tested in CI + +This database can be used by any project through the testapi. +Please note that projects may also use additional databases. This database is +mainly use to colelct CI results and scenario trust indicators. + +This database is also cloned for OPNFV Plugfest. + + +The test API +------------ +The Test API is used to declare pods, projects, test cases and test results. +Pods correspond to the cluster of machines (3 controller and 2 compute nodes in +HA mode) used to run the tests and defined in Pharos project. +The results pushed in the database are related to pods, projects and cases. +If you try to push results of test done on non referenced pod, the API will +return an error message. + +An additional method dashboard has been added to post-process the raw results in +the Brahmaputra release (deprecated in Colorado release). + +The data model is very basic, 5 objects are available: + * Pods + * Projects + * Testcases + * Results + * Scenarios + +For detailed information, please go to http://artifacts.opnfv.org/releng/docs/testapi.html + + +The reporting +------------- +The reporting page for the test projects is http://testresults.opnfv.org/reporting/ + +.. figure:: ../../images/reporting_page.png + :align: center + :alt: Testing group reporting page + +This page provides a reporting per OPNFV release and per testing project. + +.. figure:: ../../images/reporting_danube_page.png + :align: center + :alt: Testing group Danube reporting page + +An evolution of this page is planned. +It was decided to unify the reporting by creating a landing page that should give +the scenario status in one glance (it was previously consolidated manually +on a wiki page). + +The landing page (planned for Danube 2.0) will be displayed per scenario: + * the status of the deployment + * the score of the test projectS + * a trust indicator + +Additional filters (version, installer, test collection time window,... ) are +included. + +The test case catalog +--------------------- +Until the Colorado release, each testing project was managing the list of its +test cases. It was very hard to have a global view of the available test cases +among the different test projects. A common view was possible through the API +but it was not very user friendly. +In fact you may know all the cases per project calling: + + http://testresults.opnfv.org/test/api/v1/projects//cases + +with project_name: bottlenecks, functest, qtip, storperf, vsperf, yardstick + +It was decided to build a web site providing a consistent view of the test cases +per project and allow any scenario owner to build his/her custom list of tests +(Danube 2.0). + +Other resources +=============== + +wiki: https://wiki.opnfv.org/testing + +mailing list: test-wg@lists.opnfv.org + +IRC chan: #opnfv-testperf + +weekly meeting (https://wiki.opnfv.org/display/meetings/TestPerf): + * Usual time: Every Thursday 15:00-16:00 UTC / 7:00-8:00 PST + * APAC time: 2nd Wednesday of the month 8:00-9:00 UTC + +======================= +Reference documentation +======================= + ++----------------+---------------------------------------------------------+ +| Project | Documentation links | ++================+=========================================================+ +| Bottlenecks | https://wiki.opnfv.org/display/bottlenecks/Bottlenecks | ++----------------+---------------------------------------------------------+ +| CPerf | https://wiki.opnfv.org/display/cperf | ++----------------+---------------------------------------------------------+ +| Dovetail | https://wiki.opnfv.org/display/dovetail | ++----------------+---------------------------------------------------------+ +| Functest | https://wiki.opnfv.org/display/functest/ | ++----------------+---------------------------------------------------------+ +| Qtip | https://wiki.opnfv.org/display/qtip | ++----------------+---------------------------------------------------------+ +| Storperf | https://wiki.opnfv.org/display/storperf/Storperf | ++----------------+---------------------------------------------------------+ +| VSperf | https://wiki.opnfv.org/display/vsperf | ++----------------+---------------------------------------------------------+ +| Yardstick | https://wiki.opnfv.org/display/yardstick/Yardstick | ++----------------+---------------------------------------------------------+ -- cgit 1.2.3-korg
