8. Conformance¶
The objective of this chapter is to provide an automated mechanism to validate OpenStack based cloud infrastructure against the standard set of requirements defined in Architecture Requirements. Through this validation mechanism, a provider of cloud infrastructure will be able to test their cloud infrastructure’s conformance to this reference architecture. This will ease the integration of network functions into operator environments that host compatible cloud infrastructures, thereby reducing cost, complexity, and time of integration.
The overall workstream requires the close coordination of the following:
Requirements - The agreed upon capabilities and conditions that a compliant cloud infrastructure must provide or satisfy.
Tests - The verification mechanism that determines that a given cloud infrastructure complies with one or more requirements.
Conformance Specifications - The definition of the requirements, tests, and circumstances (test case integration, etc.) that must be met to be deemed conformant.
8.1. Requirements and Testing Principles¶
If there is no clear traceability and strong links between Requirements, Tests, and Conformance Specifications, then it becomes difficult to determine if a cloud infrastructure is compliant. With this in mind, below are the set of recommended principles for each of the three components to follow. Adherence to these principles will provide the following:
Enable clear progress tracking and linkage between independent projects (i.e. know what has and has not been covered, and track changes over time)
Help users better understand if they meet requirements
Provide a stable set of point-in-time requirements and tests to achieve conformance
Reduce ambiguity in testing, requirements, and conformance
Testing Principles:
There must be traceability between test cases and requirement being validated
Failures should provide additional content to inform the user where or how the requirement was violated (e.g. which file or resource violated the requirement). Put another way, do not require the user to read the test to understand what went wrong
Testing tools should support selection of tests based on category or profile.
Tests must be available to run locally by both VNF and cloud infrastructure providers
Testing tools must produce machine-readable result formats that can be used as input into any badging program
Conformance Specifications:
Conformance specifications must refer to or define the versioned requirements that must be satisfied
Conformance specifications must refer to the versioned test implementations that must be used to validate the requirements
Conformance specifications must define the expected preconditions and environment requirements for any test tooling
Conformance specifications must define which tests must be executed in the given testing tools to achieve conformance
The conformance specifications must provide the mapping between tests and requirements to demonstrate traceability and coverage.
8.2. Test Case Integration and Tooling¶
The OpenStack based cloud infrastructure suite must utilise the Anuket test case integration toolchain to deliver overall integration, the same end user actions, and a unique test result format (e.g. Anuket test result database) needed by the end users and any test case result verification program (e.g. OVP [126]).
8.2.1. Anuket Toolchains¶
Anuket, previously named OPNFV, has built a complete CI/CD toolchain for continuously deploying and testing cloud infrastructure.
As for all installer projects, Jenkins [127] triggers scenario deployments, runs the Anuket gating test cases and then publishes all test results in the centralised test database [128] and all artifacts (reports, logs, etc.) to an S3 compatible storage service [129].
The verification, validation, and conformance processes leverage existing Anuket testing knowledge (projects) and experience (history) by utilising the toolchain design already in-place. The conformance toolchain only requires for the local deployment of the components instead of leveraging the common Anuket centralised services. However, the interfaces remain unchanged for leveraging test jobs, the common test case execution, the test result database and the S3 protocol to publish the artifacts. It’s worth mentioning that dumping all results and logs required for conformance is already in place in Functest daily jobs (see functest-wallaby-zip [130].
It should be noted that Xtesting CI [131] supports both centralised and distributed deployment models as described before. It has deployed the full toolchain in one small virtual machine to verify ONAP Openlab via Functest.
8.2.2. Test Case Integration¶
To reach all goals in terms of verification, validation, compliance, and conformance, all test cases must be delivered as Docker containers [132] to simplify the CI toolchain setup including:
the common test case execution
the unified way to manage all the interactions with the CI/CD components and with third-parties (e.g. dump all test case logs and results for conformance)
For their part, the Docker containers simply enforce that the test cases are delivered with all runtime dependencies. This prevents lots of manual operations when configuring the servers running the test cases and prevents conflicts between the test cases due to any dependencies.
It’s worth mentioning that all the conformance test cases already leverage Xtesting [133] which is a simple framework to assemble sparse test cases and to accelerate the adoption of CI/CD best practices. By managing all the interactions with the CI/CD components (test scheduler, test results database, artifact repository), it allows the developer to work only on the test suites without diving into CI/CD integration. Even more, it brings the capability to run heterogeneous test cases in the same CI toolchains thanks to a few, quickly achievable constraints [134].
The Docker containers proposed by the test projects must also embed the Xtesting Python package [135] and the related test case execution description files [136] as required by Xtesting.
8.2.3. Testing Cookbooks¶
Xtesting CI [131] leverages the common test case execution proposed by Xtesting. Thanks to a simple test case list, this tool deploys plug-and-play CI/CD toolchains in a few commands [137]. In addition, it supports multiple components such as Jenkins and Gitlab CI (test schedulers) and multiple deployment models [138] such as all-in-one or centralised services.
Xtesting [133] and Xtesting CI [131] combined meet the requirements about verification, validation, compliance, and conformance:
smoothly assemble multiple heterogeneous test cases
generate the Jenkins jobs in Anuket Releng [139] to verify conformance with Anuket specifications
deploy local CI/CD toolchains everywhere to check conformance with Anuket specifications
dump all test case results and logs [140] for third-party conformance review
Here are a couple of publicly available playbooks :
8.3. Conformance Test Suite¶
8.3.1. Functest in a nutshell¶
Functest [145] was initially created to verify OPNFV Installers and Scenarios and then to publish fair, trustable, and public results regarding the status of the different open-source technologies, especially for Neutron backends (e.g., Neutron agents, OpenDaylight, OVN, etc.). It has been continuously updated to offer the best testing coverage for any kind of OpenStack and Kubernetes deployments including production environments. It also ensures that the platforms meet Network Functions Virtualisation requirements by running and testing VNFs amongst all tests available.
Functest is driven by a true verification of the platform under test as opposed to the interoperability programs such as RefStack [146] or OPNFV Verification Program [126] which select a small subset of Functional tests passing in many different open-source software combinations:
tests are skipped if an optional support is missing (e.g. Barbican [68] or networking features such as such as BGPVPN interconnection [147] or Service Function Chaining [148])
tests are parameterised (e.g. shared vs non-shared live migration)
blacklist mechanisms are available if needed
It should be noted that the RefStack lists [146] are included as they are in Functest in the next 3 dedicated testcases:
refstack_compute (OpenStack Powered Compute)
refstack_object (OpenStack Powered Object Storage)
refstack_platform (OpenStack Powered Platform)
Then Functest conforms with the upstream rules (versions, code quality, etc.) and especially their gates [149] (a.k.a. the automatic verification prior to any code review) to preserve the quality between code and deployment. In that case, Functest can be considered as a smooth and lightweight integration of tests developed upstream (and the Functest team directly contributes in these projects: Rally [150], Tempest [151], etc.). It is worth mentioning that, as opposed to the OpenStack Gates leveraging on DevStack [152], it can check the same already deployed SUT over and over even from a Raspberry PI [153]. Here the testcases can be executed in parallel vs the same deployment instead of being executed vs different pools of virtual machines.
Here are the functional tests (>2000) running in OpenStack gates integrated in Functest Smoke (see Functest daily jobs [154] for more details):

Functest should be considered as a whole as it meets multiple objectives about the reference implementation:
verify all APIs (services, advances, features, etc.) exposed by the reference implementation
compare the reference implementation and local deployments from a functional standpoint and from OpenStack control plane and dataplane capabilities

8.3.2. Test Case traceability¶
8.3.2.1. Interfaces & APIs¶
The OpenStack Gates [149] verify all changes proposed mostly by running thousands of Tempest tests completed by Rally scenarios in a few cases. Skipping tests is allowed in all OpenStack Gates and only failures rate the review -1 because of the multiple capabilities and backends selected in the different Gate jobs. The classical Functest containers [156] conform to this model which also fits the heterogeneous user deployments.
From an OpenStack based cloud infrastructure conformance state point, the capabilities are well described in Interfaces and APIs which allows tuning the test configurations and the test lists to avoid skipping any test. It results that all tests covering optional capabilities and all upstream skipped tests due to known bugs are not executed. All remaining tests must be executed and must pass successfully.
New Functest containers [158] have been proposed for Anuket Compliance which simply override the default test configurations and the default test lists. Any optional capability or services (e.g. Barbican) can be still verified by the classical Functest containers.
The next subsections detail the Tempest tests which must not be executed from a compliance state point. The remaining tests have to pass successfully. They cover all together the API testing requirements as asked by Interfaces and APIs

8.3.2.4. Dataplane benchmarking¶
Functest Benchmarking CNTT [185] offers two benchmarking dataplane test cases leveraging on:
VMTP [188] is a small python application that will automatically perform ping connectivity, round trip time measurement (latency) and TCP/UDP throughput measurement on any OpenStack deployment.
[189] wraps around popular system network testing tools like iperf, iperf3 and netperf (with help of flent). [189] is able to deploy OpenStack instances and networks in different topologies. [189] scenario specifies the deployment and list of tests to execute.
The SLA is the default SLA proposed in Functest Benchmarking CNTT [185].
8.3.2.4.1. VMTP¶
Here are the scenarios [190] executed by Functest [191]: - VM to VM same network fixed IP (intra-node) - VM to VM different network fixed IP (intra-node) - VM to VM different network floating IP (intra-node) - VM to VM same network fixed IP (inter-node) - VM to VM different network fixed IP (inter-node) - VM to VM different network floating IP (inter-node)

8.3.2.5. Open-source VNF onboarding and testing¶
Running open-source VNFs is a key technical solution to ensure that the platforms meet Network Functions Virtualisation requirements. Functest VNF [193] offers 5 test cases which automatically onboard and test the following 3 open-source VNFs:
Here are the full list of orchestrators used for all these deployments:
The VNF are covered by upstream tests when possible (see clearwater-live-test [199]) and by Functest VNF tests in the other cases.

8.5. OpenStack Testing Cookbook¶
Please note the next two points depending on the GNU/Linux distributions and the network settings:
SELinux: you may have to add –system-site-packages when creating the virtualenv (“Aborting, target uses selinux but python bindings (libselinux-python) aren’t installed!”)
Proxy: you may set your proxy in env for Ansible and in systemd for Docker [200]
To deploy your own CI toolchain running OpenStack based cloud infrastructure Conformance:
virtualenv functest --system-site-packages
. functest/bin/activate
pip install ansible
ansible-galaxy install collivier.xtesting
ansible-galaxy collection install ansible.posix community.general community.grafana kubernetes.core community.docker community.postgresql
git clone https://gerrit.opnfv.org/gerrit/functest functest-src
(cd functest-src && git checkout -b stable/wallaby origin/stable/wallaby)
ansible-playbook functest-src/ansible/site.cntt.yml
8.5.1. OpenStack API testing configuration¶
Here is the default Functest tree as proposed in Functest Wallaby [156]:
/home/opnfv/functest/openstack.creds
/home/opnfv/functest/images
Download the images and fill /home/opnfv/functest/openstack.creds as proposed in Functest Wallaby [156].
You may have to modify a few Functest env vars according to the SUT (see env in Functest Wallaby [156]). Be free to modify functest-src/ansible/host_vars/127.0.0.1 at your convenience and then to reconfigure the toolchain:
ansible-playbook functest-src/ansible/site.cntt.yml
8.5.2. Run OpenStack based cloud infrastructure Conformance¶
Open http://127.0.0.1:8080/job/functest-wallaby-daily/ in a web browser, login as admin/admin and click on “Build with Parameters” (keep the default build_tag value).
If the System under test (SUT) is compliant, a link to the full archive containing all test results and artifacts will be printed in functest-wallaby-zip’s console. Be free to download it and then to send it to any reviewer committee.
To clean your working directory:
deactivate
rm -rf functest-src functest
