Why another testing tool?
I have used Jenkins before. I was maintaining one instance in one of my VPS instance. The amount of RAM required by Jenkins was too much for my small VM. I can admit that I am not a great sys-admin anyway.
As part of my daily job, I have to test the latest cloud images we build under Fedora project. While doing so, I figured out that most of it can be automated if we have a system to create/maintain/terminate cloud instances. Of course I do not want any actual cloud, it will be a different monster to maintain.
This is the point where I came up with Tunir. Tunir is a simple testing tool that will help me run automated tests for the cloud images. I kept the system generic enough to execute any kind of tests people want.
The configuration is very minimal with Tunir. There is also a golang verion called gotun which has better option to run the tests inside OpenStack or AWS.
