CNF Test Suite

| Main | | ------------------------------------------------------------------------------------------------------------------------------------------- | | Build Status |

The CNF Test Suite is a tool that validates telco application's (i.e. Cloud Native Network Functions - CNFs) adherence to cloud native principles and best practices.

This Test Suite initiative works closely with the CNF WG which determines requirements for the CNF Test Suite program.

Installation and Usage

To get the CNF Test Suite up and running, see the Installation Guide.

To give it a try immediately you can use these quick install steps

Prereqs: kubernetes cluster, wget, curl, helm 3.1.1 or greater on your system already.

  1. Install the latest test suite binary: source <(curl -s https://raw.githubusercontent.com/cncf/cnf-testsuite/main/curl_install.sh)
  2. Run setup to prepare the cnf-testsuite: cnf-testsuite setup
  3. Pull down an example CNF configuration to try: curl -o cnf-testsuite.yml https://raw.githubusercontent.com/cncf/cnf-testsuite/main/example-cnfs/coredns/cnf-testsuite.yml
  4. Initialize the test suite for using the CNF: cnf-testsuite cnf_setup cnf-config=./cnf-testsuite.yml
  5. Run all of application/workload tests: cnf-testsuite workload

Implementation overview

The CNF Test Suite leverages upstream tools such as OPA Gatekeeper, Helm linter, and Promtool for testing CNFs. The upstream tool installation, configuration, and versioning has been made repeatable.

The test framework and tests (using the upstream tools) are written in the human-readable, compiled language, Crystal. Common capabilities like dependencies between tests and categories are supported.

Setup of vanilla upstream K8s on Equinix Metal is done with the CNF Testbed platform tool chain, which includes k8s-infra, Kubespray. To add support for other providers, please submit a Pull Request to the CNF Testbed repo.
