Each testcase can generate -logs. - -Since Colorado we introduce the possibility to push the logs to the artifact. -A new script (https://git.opnfv.org/releng/tree/utils/push-test-logs.sh) has -been created for CI. - -When called, and assuming that the POD is authorized to push the logs to -artifacts, the script will push all the results or logs locally stored under -/home/opnfv/functest/results/. - -If the POD is not connected to CI, logs are not pushed. -But in both cases, logs are stored in /home/opnfv/functest/results in the -container. -Projects are encouraged to push their logs here. - -Since Colorado it is also easy for feature project to integrate this feature by -adding the log file as output_file parameter when calling execute_command from -functest_utils library - - ret_val = functest_utils.execute_command(cmd, output_file=log_file) - - -How does Functest deal with VNF onboarding? -=========================================== - -VNF onboarding has been introduced in Brahmaputra through the automation of a -clearwater vIMS deployed thanks to cloudify orchestrator. - -This automation has been described at OpenStack summit Barcelona: -https://youtu.be/Jr4nG74glmY - -The goal of Functest consists in testing OPNFV from a functional perspective: -the NFVI and/or the features developed in OPNFV. Feature test suites are -provided by the feature project. Functest just simplifies the integration of -the suite into the CI and gives a consolidated view of the tests per scenario. - -Functest does not develop VNFs. - -Functest does not test any MANO stack. - -OPNFV projects dealing with VNF onboarding ------------------------------------------- - -Testing VNF is not the main goal however it gives interesting and realistic -feedback on OPNFV as a Telco cloud. - -Onboarding VNF also allows to test a full stack: orchestrator + VNF. - -Functest is VNF and MANO stack agnostic. - -An internship has been initiated to reference the Open Source VNF: Intern -Project Open Source VNF catalog - -New projects dealing with orchestrators or VNFs are candidate for Danube. - -The 2 projects dealing with orchestration are: - - * orchestra (Openbaton) - * opera (Open-O) - -The Models project address various goals for promoting availability and -convergence of information and/or data models related to NFV service/VNF -management, as being defined in standards (SDOs) and as developed in open -source projects. - -Functest VNF onboarding ------------------------ - -In order to simplify VNF onboarding a new abstraction class has been developed -in Functest. - -This class is based on vnf_base and can be described as follow: - - +------------+ +--------------+ - | test_base |------------>| vnf_base | - +------------+ +--------------+ - |_ prepare - |_ deploy_orchestrator (optional) - |_ deploy_vnf - |_ test_vnf - |_ clean - - -Several methods are declared in vnf_base: - - * prepare - * deploy_orchestrator - * deploy_vnf - * test_vnf - * clean - -deploy_vnf and test_vnf are mandatory. - -prepare will create a user and a project. - -How to declare your orchestrator/VNF?
