Introduction
This document covers both ELIOT Blueprint Use Case.
ELIOT is "Enterprise Edge Lightweight and IOT" project under Akraino approved blueprint family and part of Akraino Edge Stack, which intends to develop a fully integrated edge network infrastructure and running edge computing applications on lightweight Edge Nodes. ELIOT targets on making the edge node a lightweight software stack which can be deployed on edge nodes which have limited hardware capacity by leveraging lightweight OS, container running environment and container orchestration applications.
In addition ELIOT stack focuses to have infrastructure for edge computing which will enable high performance, high availability, security and reduce latency.
Akarino Test Group Information
The Test Environment consists of two topology :
- ELIOT topology with Kubernetes Cluster + EdgexPlatform
- ELIOT topology with KubeEdge
Overall Test Architecture
ELIOT topology with Kubernetes Cluster.
ELIOT Manager and single ELIOT Edge Node are installed VM having Ubuntu 16.04.
In ELIOT Manager the setup.sh is executed which internally installs docker ,k8s and tests k8s deployment by deploying nginx on ELIOT Edge Node
ELIOT topology with KubeEdge
ELIOT Manager and single ELIOT Edge Node are installed VM having Ubuntu 16.04.
In ELIOT Manager Docker, K8S , KubeEdge-EdgeController is installed and in ELIOT Edge Docker and KubeEdge-EdgeCore is installed.
In the KubeEdge init command the nginx is deployed in ELIOT - Edge Core.

ELIOT Platform Test
covers Test Deployment Environment and Test Case Result for ELIOT IoT Gateway Blueprint.
The number of nodes in the ELIOT Cluster remains same as Release 1.0 ; one virtual machine node for ELIOT Manager and one Virtual Node for ELIOT Edge Node (IoT Gateway)
The changes include testing of the new software included in the ELIOT Platform Stack.

Overall Test Architecture
ELIOT Cluster Number of Nodes remains same as Release 1.0
- One Node for ELIOT Manager.
- One Node for ELIOT Edge Node.
Both the nodes are running on Virtual Machine.
In Release 1.0 the Test Environments were :-
- ELIOT Cluster with Kubernetes on Ubuntu OS.
- ELIOT Cluster with KubeEdge on Ubuntu OS
In Release 2.0 the Test Environments are :-
- ELIOT Cluster with Kubernetes + EdgeX Platform on Ubuntu OS.
- ELIOT Cluster with Kubernetes + OPC-UA on Tailored OS
- ELIOT Cluster with KubeEdge on Cent OS

Test API description
Some test cases are re-used from Release 1.0 . Test cases are marked as inherited from Release 1.0 and New Test Cases.
1. Deployment Type 1 Test Environment
ELIOT Cluster with Kubernetes + EdgeX Platform on Ubuntu OS
1.1 ELIOT Platform Test
Test Case 1: NGINX deployment verification.
(Inherited from Release 1.0)
Test inputs:
Execute the bootstrap script to setup the ELIOT platform. The bootstrap script internally invokes verifyk8s.sh script.
verifyk8s.sh script check if the nginx pod is deployed and running in the ELIOT Cluster. If not returns non zero value.
Test Procedure
The setup.sh script will deploy nginx pod in the ELIOT Edge Node after Kubernetes Installation.
Manual Check : execute kubectl get pods
Expected output
It will check nginx deployment and result the details in the log. If the nginx pod is not in running state after 10 retry setup.sh script will return value 1.
(CI Job fails if the return value is 1)
