Testing

Continous Integration is an integral part of Node. The fact that there is also an Engine appliance is very beneficial.

Overview

• Engine and Node appliances are spawned in distinct, but connected, (user-session) VMs
• virt-install is used to setup the VMs
• cloud-init is used to do the basic OS configuration (passwords, ssh, and IP configuration) Note: cloud-init is not built into the squashfs, it will be installed on-demand by the testing infrastructure.
• Python's unittest infrastructure is used to provide the testing framework

A reference implementation is part of the ovirt-appliance repository.

This setup is very convenient because it provides the following:

• Environment setup during testsuite creation (includes VM creation, configuration and initial snapshot)
• Resetting to the initial snapshot for each testcase
• SSH to perform in VM operations
• virsh to control VM lifecycle (reboot, shutdown)
