Akarino Test Group Information

N/A

Testing has been carried out at Fujitsu Limited labs without any Akraino Test Working Group resources.

Overall Test Architecture

Tests are carried out on the architecture shown in the diagram below.

Test Bed

The test bed consists of 4 VMs running on x86 hardware, performing deploy and ci/cd and build and master node roles, two edge nodes on ARM64 (Jetson Nano) hardware, and two sensor nodes on ARM32 (Raspberry Pi) hardware.

Node Type	Count	Hardware	OS
CI/CD	1	Intel i5, 2 cores VM	Ubuntu 20.04
Build	1	Intel i5, 2 cores VM	Ubuntu 20.04
Deploy	1	Intel i5, 2 cores VM	Ubuntu 20.04
Master	1	Intel i5, 2 cores VM	Ubuntu 20.04
Edge	2	Jetson Nano, ARM Cortex-A57, 4 cores	Ubuntu 20.04
Camera	2	H.View HV-500E6A	N/A (pre-installed)

The Build VM is used to run the BluVal test framework components outside the system under test.

Test Framework

BluVal and additional tests are carried out using Robot Framework.

Test API description

Before running the tests below, ensure that the configuration in the chapter Verifying the Setup of Smart Data Transaction for CPS R7 Installation Guide has been implemented.

CI/CD Regression Tests: Node Setup

This set of test cases confirms the scripting to change the default runtime of edge nodes.

The Test inputs

The test scripts and data are stored in the source repository's cicd/tests/sdt_step2/install/ directory.

Test Procedure

The test bed is place in a state where all nodes are prepared with required software. No EdgeX or Kubernetes services are running.

Execute the test scripts:

robot cicd/tests/sdt_step2/install/

Expected output

The test scripts will change the default runtime of edge nodes from runc to nvidia.

The robot command should report success for all test cases.

Test Results

Nexus URL: https://nexus.akraino.org/content/sites/logs/fujitsu/job/sdt/r7/lfedge-install/14/

Pass (1/1 test case)

CI/CD Regression Tests: Images Build & Push

These test cases verify that the images for EdgeX microservices can be constructed, and pushed to private registry.

The Test inputs

The test scripts and data are stored in the source repository's cicd/tests/sdt_step2/build/ directory.

Test Procedure

The test bed is placed in a state where all nodes are prepared with required software and the Docker registry is running.

Execute the test scripts:

robot cicd/tests/sdt_step2/build/

Expected output

The test scripts will build images of changed services(sync-app/image-app/device-camera), add push the images to private registry.

The robot command should report success for all test cases.

Test Results

Nexus URL: https://nexus.akraino.org/content/sites/logs/fujitsu/job/sdt/r7/lfedge-build/5

Pass (2/2 test cases)

CI/CD Regression Tests: Cluster Setup & Teardown

These test cases verify that the Kubernetes cluster can be initialized, edge nodes added to it and removed, and the cluster torn down.

The Test inputs

The test scripts and data are stored in the source repository's cicd/tests/sdt_step2/cluster/ directory.

Test Procedure

The test bed is placed in a state where all nodes are prepared with required software and the Docker registry is running. The registry must be populated with the Kubernetes and Flannel images from upstream.

Execute the test scripts:

robot cicd/tests/sdt_step2/cluster/

Expected output

The test scripts will start the cluster, add all configured edge nodes, remove the edge nodes, and reset the cluster.

The robot command should report success for all test cases.

Test Results

Nexus URL: https://nexus.akraino.org/content/sites/logs/fujitsu/job/sdt/r7/lfedge-cluster/6

Pass (4/4 test cases)

CI/CD Regression Tests: EdgeX Services

These test cases verify that the EdgeX micro-services can be started and that MQTT messages are passed to the master node from the services.

The Test inputs

The test scripts and data are stored in the source repository's cicd/tests/sdt_step2/edgex/ directory.

Test Procedure

The test bed is placed in a state where the cluster is initialized and all edge nodes have joined. The Docker registry and mosquitto MQTT broker must be running on the master node. The registry must be populated with all upstream images and custom images. Either the device-camera service should be enabled, or device-virtual should be enabled to provide readings.

Execute the test scripts:

robot cicd/tests/sdt_step2/edgex/

Expected output

The test scripts will start the EdgeX micro-services on all edge nodes, confirm that MQTT messages are being delivered from the edge nodes, and stop the EdgeX micro-services.

The robot command should report success for all test cases.

Test Results

Nexus URL: https://nexus.akraino.org/content/sites/logs/fujitsu/job/sdt/r7/edgex-install/7/

Pass (8/8 test cases)

CI/CD Regression Tests: Camera Device Service

These test cases verify that the device-camera service can get image from IP Camera, the sync-app service can share the image to other edge node, the image-app service can analyze the image, and the support-notification can receive the crowded notification.

The Test inputs

The test steps and data are contained in the scripts in the source repository cicd/tests/sdt_step2/camera/ directory.

Test Procedure

The test bed is initialized to the point of having all EdgeX services running, with device-camera and image-app enabled.

Execute the test scripts:

robot cicd/tests/sdt_step2/camera/

Expected output

The test cases will check if MQTT messages and the core-data service containing the data of image acquisition, image sharing and image analysis, and check whether the support-notification service having the notification data of crowded after setting the crowded rule.

The Robot Framework should report success for all test cases

The results compare with the Lynis Incubation: PASS/FAIL Criteria, v1.0 as follows.

The Lynis Program Update test MUST pass with no errors.

2022-09-14 16:19:49 Test: Checking for program update...
2022-09-14 16:19:49 Result: Update check failed. No network connection?
2022-09-14 16:19:49 Info: to perform an automatic update check, outbound DNS connections should be allowed (TXT record).
2022-09-14 16:19:49 Suggestion: This release is more than 4 months old. Check the website or GitHub to see if there is an update available. [test:LYNIS] [details:-] [solution:-]

The test environment is a proxied private network inside the Fujitsu corporate network which does not allow direct DNS lookups using tools such as dig. Therefore the update check cannot be performed automatically.

The latest version of Lynis, 3.0.8 at time of execution, was downloaded and run directly on the SUT. See the link below:

Kube-Hunter

Nexus URL: https://nexus.akraino.org/content/sites/logs/fujitsu/job/sdt/r7/sdt-bluval/1/

There are no reported vulnerabilities. Note, this release includes fixes for vulnerabilities found in release 6. See the release 6 test document for details on those vulnerabilities and the fixes.

Note that the results still show one test failure. The "Inside-a-Pod Scanning" test case reports failure, apparently because the log ends with "Kube Hunter couldn't find any clusters" instead of "No vulnerabilities were found." This also occurred during release 6 testing. Because vulnerabilities were detected and reported in release 6 by this test case, and those vulnerabilities are no longer reported, we believe this is a false negative, and may be caused by this issue: https://github.com/aquasecurity/kube-hunter/issues/358
