Ansible Role and Collection Testing With Molecule

Elevating Ansible Development through Systematic Testing and Iterative Refinement in Molecule Scenarios

Introduction

Molecule, the testing framework for Ansible roles and playbooks, introduces powerful functionality through its concept of scenarios. Think of a scenario as a test suite for roles or playbooks within an Ansible collection. This article delves into Molecule scenarios, their layout, and how to harness their capabilities for efficient testing and development.

Ansible Collection

Adding Molecule to your Ansible collection is a straightforward process that enhances your development and testing workflow. Start by creating a new directory within your collection named “extensions.” Navigate to this newly created directory using the command line and then initialize a new default Molecule scenario with the following:

cd <path to your collection>/extensions/
molecule init scenario

This step sets the foundation for incorporating Molecule into your collection, allowing you to seamlessly integrate testing and development practices. The newly created…
