Test Driven Development with Ansible

Pooja Salpekar (~pooja-salpekar)




“When deploying and administering large infrastructures, it is still common to think in terms of individual machines rather than view an entire infrastructure as a combined whole. This standard practice creates many problems, including labor-intensive administration, high cost of ownership, and limited generally-available knowledge or code usable for administering large infrastructures.”— Steve Traugott and Joel Huddleston

Server infrastructure has traditionally lagged far behind our development practices in terms of code quality, testing, continuous integration and continuous development.

When you write your Ansible scripts or any other CM, you are coding, and every code is prone to defects. All of us understand the benefits of test-driving the application code. The same applies to your infrastructure code. Testing becomes even more significant in case of deployments spanning large clusters of nodes.

Test-driving allows the infrastructure teams to have confidence that their configuration changes are being applied as intended across many different systems, and having the intended effect. This allows the whole system to be trusted, and then updated without fear for introducing breaking changes or otherwise causing instability.

The objective is to cover agile lifecycle of infrastructure code and provide a quick demo of how to test drive Ansible scripts.
