Do you use testing for Ansible Role?

Yes, testing an Ansible Role is an important practice to ensure quality and stability of automation. Common tools used include:

• Molecule — a testing framework for Ansible roles that allows running scenarios in isolated containers or virtual machines.
• Testinfra — a library for writing infrastructure tests in Python.

Example of a simple test with Molecule:

1. Create a role and initialize Molecule:

molecule init role myrole
cd myrole
molecule init scenario --scenario-name default

2. Write tests in molecule/default/tests/test_default.py using Testinfra.

3. Run the tests:

molecule test

This allows verifying that the role correctly applies configuration and reaches the desired system state.
