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 a VM running on x86 hardware, performing jump host/deploy and master node roles, two edge nodes on ARM64 (Jetson Nano) hardware, and two sensor nodes on ARM32 (Raspberry Pi) hardware.

A second 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

CI/CD Regression Tests: Docker Private Registry

This set of test cases confirms the Docker private registry setup, population, and tear-down procedures.

The Test inputs

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

Test Procedure

The test bed is placed in a state with the deploy and master node setup complete, but with Kubernetes, EdgeX, and the private registry not running.

Execute the test scripts:

robot cicd/tests/docker

Expected output

The test script will start the registry, pull upstream images and populate the registry, clean images left over from the pull process, stop the registry, and remove the registry. The robot command should report success for all test cases.

Test Results

Pass

CI/CD Regression Tests: Node Setup

This set of test cases confirms the scripting to initialize master and edge nodes.

The Test inputs

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

Test Procedure

The test bed is place in a state where only the deploy node is initialized. No EdgeX or Kubernetes services are running. For a complete test, the master and edge nodes should not have any software installed that was not installed as part of the OS installation.

Execute the test scripts:

robot cicd/tests/install

Expected output

The test scripts will initialize the master and edge nodes and verify the required software is installed. The robot command should report success for all test cases.

Test Results

Pass

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/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/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

Pass

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/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-lora service should be enabled with dht2lra service running on the sensor nodes, or device-virtual should be enabled to provide readings.

Execute the test scripts:

robot cicd/tests/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

Pass

CI/CD Regression Tests: LoRa Device Service

These test cases verify that the LoRa device service can read sensor data over the LoRa communications channel.

The Test inputs

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

Test Procedure

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

The dht2lra service is started on the two sensor nodes.

Execute the test scripts:

robot cicd/tests/lora

Expected output

The test cases will check if MQTT messages containing temperature data gathered from the sensor nodes are arriving at the master node on the topic for each each edge node, validating that the LoRa device support is functioning.

The Robot Framework should report success for all test cases.

Test Results

Pass

Steps To Implement Security Scan Requirements

Test Procedure

1. Deploy a Test VM
2. Copy the folder ~/.kube from Kubernetes master node to the Test VM
3. Create SSH Key to access Kubernetes master node

Vuls

We use Ubuntu 20.04, so we run Vuls test as follow:

Steps To Implement Security Scan Requirements#Vuls

1. Create directory

   $ mkdir ~/vuls $ cd ~/vuls $ mkdir go-cve-dictionary-log goval-dictionary-log gost-log

2. Fetch NVD

   $ docker run --rm -it \ -v $PWD:/go-cve-dictionary \ -v $PWD/go-cve-dictionary-log:/var/log/go-cve-dictionary \ vuls/go-cve-dictionary fetch nvd

3. Fetch OVAL

   $ docker run --rm -it \ -v $PWD:/goval-dictionary \ -v $PWD/goval-dictionary-log:/var/log/goval-dictionary \ vuls/goval-dictionary fetch ubuntu 16 17 18 19 20

4. Fetch gost

   $ docker run --rm -i \ -v $PWD:/gost \ -v $PWD/gost-log:/var/log/gost \ vuls/gost fetch ubuntu

5. Create config.toml

   [servers] [servers.master] host = "192.168.2.16" port = "22" user = "test-user" keyPath = "/root/.ssh/id_rsa"

6. Start vuls container to run tests

   $ docker run --rm -it \ -v ~/.ssh:/root/.ssh:ro \ -v $PWD:/vuls \ -v $PWD/vuls-log:/var/log/vuls \ -v /etc/localtime:/etc/localtime:ro \ -e "TZ=Asia/Tokyo" \ vuls/vuls scan \ -config=./config.toml

7. Get the report

   $ docker run --rm -it \ -v ~/.ssh:/root/.ssh:ro \ -v $PWD:/vuls \ -v $PWD/vuls-log:/var/log/vuls \ -v /etc/localtime:/etc/localtime:ro \ vuls/vuls report \ -format-list \ -config=./config.toml
