Ansible testing with Molecule example

Ansible Molecule test example

This repo contains example of how Molecule can be used and incorporated into Ansible Development Lifecycle

The why

Test techniques play an important role in development, and this is no different when we are talking about Infrastructure as Code (IaC).

Developers are always testing, and constant feedback is crucial to drive development. If it takes too long to get feedback on a change, steps might be too large, identifying te breaking changes becomes hard to spot.

Baby steps and fast feedback are the important parts in TDD (test-driven development).

Molecule

This is an example for how Molecule can be used to test the state of the automation.

In this example we are using Testinfra to test the automation.

Ansible as verifier can also be used to test. Here is an example blog post on how to use Ansible to verify within molecule.
