Introduction
<Details about Additional tests required for this Blue Print in addition to the Akraino Validation Feature Project>
REC Blueprint is deployed and validated in Nokia Espoo and AT&T Middletown Radio Edge Cloud Validation Labs. Deployment of REC and test cases have been run automatically with different clusters such as Nokia OpenEdge, Dell and HP Gen 10. REC feature testing is based on Cloud TAF (Test Automation Framework), which tests basic k8s features. Results of deployments and testing are publicly available in LF Akraino nexus servers.

Test suites:
- post-install (8 test cases)
- kube-namespace (1 test case)
- kube-service (1 test case)
- smoke-tests (6 test cases)
- pm-supports (2 test cases)
Test cases:
| # | Test suite | Test case | Short description |
|---|---|---|---|
| 1 | post-install | Verify Deployment | Check deployment logs (/srv/deployment/log/bootstrap.log). Looking for “Installation complete, Installation Succeeded” in log. |
| 2 | Verify Image Build Number | Show Build number. | |
| 3 | Verify Docker Version | Check version of the installed docker (needed Docker version 19.03.3) | |
| 4 | Verify Kubernetes Clusters | Check pods’ status in kube-system namespace. All pod needs to be in “Running” state. | |
| 5 | Verify State of required services | Check the services are running and active. Checked services: docker.service, kubelet.service | |
| 6 | Verify Node Functionality | Checks the state of the nodes. All nodes need to be in “Ready” state. | |
| 7 | Verify Package Manager Status | Try to pull caas/hypercube from common(?) repository. Verify the pull is in success and image is up to date. | |
| 8 | Verify Helm Caas Infra Status | Check helm status. Caas-infra helm chart execution status needs to be “DEPLOYED” | |
| 9 | kube-namespace | Verify creating and testing Namespaces | Create “test-ns” namespace. Create a pod from nginx image in test-ns namespace. Verify the pod is created. Check the pod is created in test-ns namespace. Delete the created pod and namespace. |
| 10 | kube-service | Verify creating and testing services | Create pod from nginx image. Create a service what contains the previously created pod, and targets TCP port 80 to the pod’s TCP port 80. Verify that the nginx is reachable on TCP port 80. Delete the created service and pod. |
| 11 | smoke-tests | Verify Cluster Config Management | Verify all the nodes names. Verify database: cluster size needs to be 3 (wsrep_cluster_size). |
| 12 | Verify Cluster Config Management After Reboot Management VIP Node | Reboot the VIP(?) node. Verify the restart same as ‘Verify Cluster Config Management’ test case. | |
| 13 | Verify Database Stop And Start | Stop one of the databases. Check database: cluster size needs to be 2. Start a database node. Check database: cluster size needs to be 3. | |
| 14 | Verify Create All And No Roles | Create a user with all-roles. Create a user with no roles. | |
| 15 | Verify SudoShells | Verify all the sudo-“node” user. All need to be root user. | |
| 16 | Verify Remotescript Default | Verify ‘remotescript-default’ command execution. | |
| 17 | pm-supports | PM001 | Check resource usage of the nodes (kubectl top node). |
| 18 | PM002 | Check kubectl api metrics (kubectl api-versions | grep metrics). Printout needs to be contain “custom.metrics.k8s.io/v1beta1” and “metrics.k8s.io/v1beta1”. |
