Ansible Testing with Molecule: Complete Tutorial

Testing infrastructure code is just as critical as testing application code, yet it’s often overlooked. When your Ansible playbooks deploy to production, how confident are you that they’ll work correctly? This is where Molecule comes in—a powerful testing framework designed specifically for Ansible roles. In this comprehensive tutorial, you’ll learn how to implement robust testing strategies for your Ansible automation, from basic role testing to complex multi-scenario validations. Whether you’re managing a handful of servers or orchestrating thousands of nodes, Molecule will transform how you develop and maintain your infrastructure as code.

Prerequisites

Before diving into Molecule, ensure you have the following set up:

Required Tools:

Python 3.8 or higher
Ansible 2.10 or higher
Docker (for container-based testing)
pip (Python package manager)

Knowledge Requirements:

Basic Ansible experience (roles, tasks, handlers)
Familiarity with YAML syntax
Understanding of Docker concepts
Command-line proficiency

Environment Setup: I recommend creating a dedicated Python virtual environment to avoid dependency conflicts:

python3 -m venv molecule-env
source molecule-env/bin/activate  # On Windows: molecule-env\Scripts\activate

Step 1: Installing Molecule

Molecule installation is straightforward with pip. You’ll need to install Molecule along with the Docker driver, which we’ll use for our testing scenarios.

# Install Molecule with Docker support
pip install "molecule[docker,lint]"

# Verify installation
molecule --version

Expected Output:

molecule 5.0.1 using python 3.11
    ansible:2.15.4
    default:5.0.1 from molecule
    docker:2.1.0 from molecule_plugins.docker

The installation includes several components:

Molecule core: The testing framework itself
Docker driver: Enables container-based testing
Lint tools: Ansible-lint and yamllint for code quality

Verification Checkpoint: Run molecule --version and confirm all components are installed. If Docker driver is missing, reinstall with the [docker] extra.

Step 2: Initializing a New Role

Let’s create a practical example: an Nginx web server role. Molecule integrates seamlessly with Ansible Galaxy’s role structure.

# Create a new role with Molecule testing built-in
molecule init role nginx --driver-name docker

# Navigate into the role directory
cd nginx

This command generates a complete role structure:

nginx/
├── defaults/
│   └── main.yml
├── files/
├── handlers/
│   └── main.yml
├── meta/
│   └── main.yml
├── molecule/
│   └── default/
│       ├── converge.yml
│       ├── molecule.yml
│       └── verify.yml
├── tasks/
│   └── main.yml
├── templates/
├── tests/
└── vars/
    └── main.yml

Key Directories:

molecule/default/: Contains your test scenario configuration
tasks/main.yml: Where your Ansible tasks go
handlers/main.yml: For service restarts and notifications

Step 3: Understanding Molecule Structure

The molecule/default/ directory contains three critical files:

molecule.yml - The main configuration file:

---
dependency:
  name: galaxy
driver:
  name: docker
platforms:
  - name: instance
    image: geerlingguy/docker-ubuntu2204-ansible:latest
    pre_build_image: true
provisioner:
  name: ansible
verifier:
  name: ansible

Configuration Breakdown:

dependency: Manages role dependencies from Ansible Galaxy
driver: Specifies Docker for spinning up test instances
platforms: Defines test environments (OS, image, resources)
provisioner: Uses Ansible to apply your role
verifier: Runs verification tests after convergence

converge.yml - Applies your role to test instances:

---
- name: Converge
  hosts: all
  become: true
  tasks:
    - name: "Include nginx"
      include_role:
        name: "nginx"

verify.yml - Contains assertions to validate role behavior:

---
- name: Verify
  hosts: all
  gather_facts: false
  tasks:
    - name: Example assertion
      ansible.builtin.assert:
        that: true

Step 4: Writing Your First Test

Let’s build a functional Nginx role with proper tests. Start by defining the role tasks.

tasks/main.yml:

---
# Install Nginx web server
- name: Install Nginx package
  ansible.builtin.apt:
    name: nginx
    state: present
    update_cache: yes
  notify: Start nginx

- name: Ensure Nginx is started and enabled
  ansible.builtin.service:
    name: nginx
    state: started
    enabled: yes

- name: Deploy custom index.html
  ansible.builtin.copy:
    content: |
      <html>
      <head><title>Ansible Managed</title></head>
      <body><h1>Deployed with Ansible</h1></body>
      </html>
    dest: /var/www/html/index.html
    owner: www-data
    group: www-data
    mode: '0644'

handlers/main.yml:

---
- name: Start nginx
  ansible.builtin.service:
    name: nginx
    state: started

Now create meaningful verification tests in molecule/default/verify.yml:

---
- name: Verify
  hosts: all
  gather_facts: true
  tasks:
    - name: Check if Nginx is installed
      ansible.builtin.package_facts:
        manager: auto

    - name: Assert Nginx package is present
      ansible.builtin.assert:
        that:
          - "'nginx' in ansible_facts.packages"
        fail_msg: "Nginx package is not installed"
        success_msg: "Nginx package is correctly installed"

    - name: Check if Nginx service is running
      ansible.builtin.service_facts:

    - name: Assert Nginx service is active
      ansible.builtin.assert:
        that:
          - "ansible_facts.services['nginx.service'].state == 'running'"
          - "ansible_facts.services['nginx.service'].status == 'enabled'"
        fail_msg: "Nginx service is not running or not enabled"
        success_msg: "Nginx service is active and enabled"

    - name: Check if Nginx is listening on port 80
      ansible.builtin.wait_for:
        port: 80
        timeout: 5

    - name: Verify custom index.html content
      ansible.builtin.uri:
        url: http://localhost
        return_content: yes
      register: webpage

    - name: Assert webpage contains expected content
      ansible.builtin.assert:
        that:
          - "'Deployed with Ansible' in webpage.content"
        fail_msg: "Custom index.html was not deployed correctly"
        success_msg: "Custom index.html is correctly deployed"

Step 5: Running Tests

Molecule provides a complete test lifecycle. Here’s how to execute tests:

# Run the full test sequence
molecule test

# Or run individual steps:
molecule create    # Create test instances
molecule converge  # Apply your role
molecule verify    # Run verification tests
molecule destroy   # Clean up instances

The Full Test Sequence:

When you run molecule test, Molecule executes these phases:

Dependency: Install role dependencies from Ansible Galaxy
Lint: Check syntax and best practices
Cleanup: Remove previous test instances
Destroy: Ensure clean state
Create: Spin up test containers
Prepare: Optional pre-configuration steps
Converge: Apply your role
Idempotence: Re-run to ensure no changes occur
Verify: Run assertion tests
Destroy: Clean up resources

Expected Output (abbreviated):

--> Test matrix

└── default
    ├── dependency
    ├── cleanup
    ├── destroy
    ├── create
    ├── prepare
    ├── converge
    ├── idempotence
    ├── verify
    └── destroy

--> Scenario: 'default'
--> Action: 'converge'

    PLAY [Converge] ********************************************************

    TASK [Include nginx] ***************************************************
    included: /Users/user/nginx/tasks/main.yml

    TASK [Install Nginx package] *******************************************
    changed: [instance]

    TASK [Ensure Nginx is started and enabled] *****************************
    changed: [instance]

    PLAY RECAP *************************************************************
    instance: ok=3 changed=2 unreachable=0 failed=0

--> Scenario: 'default'
--> Action: 'verify'

    TASK [Assert Nginx service is active] **********************************
    ok: [instance] => {
        "msg": "Nginx service is active and enabled"
    }

Development Workflow Tip: During development, use molecule converge repeatedly to apply changes without destroying instances. Only run the full molecule test when you’re ready to validate everything.

Step 6: Testing with Different Scenarios

Real-world infrastructure rarely runs on a single OS. Molecule scenarios let you test across multiple platforms simultaneously.

Create a multi-platform scenario by modifying molecule/default/molecule.yml:

---
dependency:
  name: galaxy
driver:
  name: docker
platforms:
  - name: ubuntu-20-04
    image: geerlingguy/docker-ubuntu2004-ansible:latest
    pre_build_image: true
  - name: ubuntu-22-04
    image: geerlingguy/docker-ubuntu2204-ansible:latest
    pre_build_image: true
  - name: debian-11
    image: geerlingguy/docker-debian11-ansible:latest
    pre_build_image: true
provisioner:
  name: ansible
  playbooks:
    converge: converge.yml
    verify: verify.yml
verifier:
  name: ansible

Creating Named Scenarios:

You can also create completely separate test scenarios for different use cases:

# Create a production-like scenario
molecule init scenario production

# Create a scenario for testing upgrades
molecule init scenario upgrade

This creates:

molecule/
├── default/
│   ├── converge.yml
│   ├── molecule.yml
│   └── verify.yml
├── production/
│   ├── converge.yml
│   ├── molecule.yml
│   └── verify.yml
└── upgrade/
    ├── converge.yml
    ├── molecule.yml
    └── verify.yml

Running Specific Scenarios:

# Test only the production scenario
molecule test -s production

# Converge multiple scenarios
molecule converge --all

Step 7: CI/CD Integration

Molecule integrates seamlessly with continuous integration pipelines. Here’s how to set it up with GitHub Actions.

.github/workflows/molecule.yml:

---
name: Molecule Tests

on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        scenario:
          - default
          - production

    steps:
      - name: Check out code
        uses: actions/checkout@v3

      - name: Set up Python
        uses: actions/setup-python@v4
        with:
          python-version: '3.11'

      - name: Install dependencies
        run: |
          python -m pip install --upgrade pip
          pip install "molecule[docker,lint]"
          pip install ansible

      - name: Run Molecule tests
        run: molecule test -s ${{ matrix.scenario }}

GitLab CI Configuration (.gitlab-ci.yml):

---
stages:
  - test

molecule:
  stage: test
  image: geerlingguy/docker-ubuntu2204-ansible:latest
  services:
    - docker:dind
  variables:
    DOCKER_HOST: tcp://docker:2375
    DOCKER_TLS_CERTDIR: ""
  before_script:
    - pip install "molecule[docker,lint]"
  script:
    - molecule test --all
  only:
    - merge_requests
    - main

Verification Checkpoint: Push your role to a Git repository and verify the CI pipeline executes successfully. Check that all scenarios pass and the pipeline fails on test failures.

Real-world Examples

Example 1: Testing a Web Server Role

Let’s extend our Nginx role with SSL configuration and virtual hosts.

tasks/main.yml (extended):

---
- name: Install Nginx and SSL dependencies
  ansible.builtin.apt:
    name:
      - nginx
      - openssl
    state: present
    update_cache: yes

- name: Create SSL directory
  ansible.builtin.file:
    path: /etc/nginx/ssl
    state: directory
    mode: '0755'

- name: Generate self-signed SSL certificate
  ansible.builtin.command:
    cmd: >
      openssl req -x509 -nodes -days 365 -newkey rsa:2048
      -keyout /etc/nginx/ssl/nginx.key
      -out /etc/nginx/ssl/nginx.crt
      -subj "/C=US/ST=State/L=City/O=Org/CN=localhost"
    creates: /etc/nginx/ssl/nginx.crt

- name: Deploy SSL virtual host configuration
  ansible.builtin.template:
    src: vhost-ssl.conf.j2
    dest: /etc/nginx/sites-available/default
    mode: '0644'
  notify: Reload nginx

- name: Ensure Nginx is started
  ansible.builtin.service:
    name: nginx
    state: started
    enabled: yes

templates/vhost-ssl.conf.j2:

server {
    listen 80;
    listen 443 ssl;

    ssl_certificate /etc/nginx/ssl/nginx.crt;
    ssl_certificate_key /etc/nginx/ssl/nginx.key;

    root /var/www/html;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
    }
}

molecule/default/verify.yml (extended):

---
- name: Verify
  hosts: all
  gather_facts: true
  tasks:
    - name: Check SSL certificate exists
      ansible.builtin.stat:
        path: /etc/nginx/ssl/nginx.crt
      register: ssl_cert

    - name: Assert SSL certificate is present
      ansible.builtin.assert:
        that:
          - ssl_cert.stat.exists
          - ssl_cert.stat.mode == '0644'

    - name: Verify Nginx is listening on HTTPS
      ansible.builtin.wait_for:
        port: 443
        timeout: 5

    - name: Test HTTPS connection
      ansible.builtin.uri:
        url: https://localhost
        validate_certs: no
        return_content: yes
      register: https_response

    - name: Assert HTTPS is working
      ansible.builtin.assert:
        that:
          - https_response.status == 200

Example 2: Testing Database Configuration

Here’s how to test a PostgreSQL role with Molecule.

molecule/default/molecule.yml:

---
platforms:
  - name: postgres-instance
    image: geerlingguy/docker-ubuntu2204-ansible:latest
    pre_build_image: true
    volumes:
      - /sys/fs/cgroup:/sys/fs/cgroup:ro
    privileged: true
    command: /lib/systemd/systemd

tasks/main.yml (PostgreSQL role):

---
- name: Install PostgreSQL
  ansible.builtin.apt:
    name:
      - postgresql
      - postgresql-contrib
      - python3-psycopg2
    state: present
    update_cache: yes

- name: Ensure PostgreSQL is started
  ansible.builtin.service:
    name: postgresql
    state: started
    enabled: yes

- name: Create application database
  become_user: postgres
  community.postgresql.postgresql_db:
    name: appdb
    state: present

- name: Create database user
  become_user: postgres
  community.postgresql.postgresql_user:
    name: appuser
    password: "{{ db_password | default('changeme') }}"
    db: appdb
    priv: ALL
    state: present

molecule/default/verify.yml:

---
- name: Verify
  hosts: all
  become: true
  tasks:
    - name: Check PostgreSQL service status
      ansible.builtin.service_facts:

    - name: Assert PostgreSQL is running
      ansible.builtin.assert:
        that:
          - "ansible_facts.services['postgresql.service'].state == 'running'"

    - name: Verify database exists
      become_user: postgres
      community.postgresql.postgresql_query:
        db: appdb
        query: SELECT 1
      register: db_check

    - name: Assert database is accessible
      ansible.builtin.assert:
        that:
          - db_check is succeeded

    - name: Test database connection with user
      become_user: postgres
      community.postgresql.postgresql_query:
        db: appdb
        login_user: appuser
        query: CREATE TABLE test (id serial PRIMARY KEY, name varchar(50))
      register: table_creation

    - name: Assert user has correct privileges
      ansible.builtin.assert:
        that:
          - table_creation is succeeded

Example 3: Testing Security Hardening

Security roles require thorough testing to ensure they don’t break functionality.

molecule/default/verify.yml (security hardening):

---
- name: Verify Security Hardening
  hosts: all
  gather_facts: true
  tasks:
    - name: Check if SSH password authentication is disabled
      ansible.builtin.lineinfile:
        path: /etc/ssh/sshd_config
        regexp: '^PasswordAuthentication'
        line: 'PasswordAuthentication no'
        state: present
      check_mode: yes
      register: ssh_config

    - name: Assert SSH is properly configured
      ansible.builtin.assert:
        that:
          - not ssh_config.changed
        fail_msg: "SSH password authentication is not disabled"

    - name: Verify firewall is active
      ansible.builtin.command: ufw status
      register: ufw_status
      changed_when: false

    - name: Assert firewall is enabled
      ansible.builtin.assert:
        that:
          - "'Status: active' in ufw_status.stdout"

    - name: Check for unattended upgrades
      ansible.builtin.stat:
        path: /etc/apt/apt.conf.d/50unattended-upgrades
      register: unattended_upgrades

    - name: Assert automatic updates are configured
      ansible.builtin.assert:
        that:
          - unattended_upgrades.stat.exists

    - name: Verify root login is disabled
      ansible.builtin.command: passwd -S root
      register: root_status
      changed_when: false

    - name: Assert root account is locked
      ansible.builtin.assert:
        that:
          - "'L' in root_status.stdout"
        fail_msg: "Root account is not locked"

Best Practices

Test Organization

Keep tests focused and modular:

# Bad: One giant verification file
verify.yml  # 500 lines of tests

# Good: Separate verification tasks
molecule/default/
├── molecule.yml
├── converge.yml
├── verify.yml
└── verify/
    ├── test_installation.yml
    ├── test_configuration.yml
    ├── test_security.yml
    └── test_networking.yml

Main verify.yml includes specific tests:

---
- name: Verify
  hosts: all
  tasks:
    - name: Run installation tests
      include_tasks: verify/test_installation.yml

    - name: Run configuration tests
      include_tasks: verify/test_configuration.yml

    - name: Run security tests
      include_tasks: verify/test_security.yml

Scenario Management

Use scenarios strategically:

default: Basic functionality testing
production: Production-like environment with all features
upgrade: Testing upgrade paths from previous versions
multi-node: Distributed system testing

Don’t create scenarios for minor variations. Instead, use variables:

# molecule/default/converge.yml
- name: Converge
  hosts: all
  vars:
    # Override these in specific scenarios
    enable_ssl: "{{ scenario_ssl | default(true) }}"
    enable_monitoring: "{{ scenario_monitoring | default(false) }}"
  roles:
    - nginx

Idempotency Testing

Idempotency is critical—running your role multiple times should not cause changes after the first run.

Molecule automatically tests this. Ensure your tasks are idempotent:

# Bad: Always reports changed
- name: Configure application
  ansible.builtin.shell: echo "config=true" >> /etc/app.conf

# Good: Idempotent configuration
- name: Configure application
  ansible.builtin.lineinfile:
    path: /etc/app.conf
    line: "config=true"
    create: yes

Monitor idempotence test output:

PLAY RECAP *****************************************************************
instance: ok=10 changed=0 unreachable=0 failed=0

If changed is greater than 0 on the second run, you have idempotency issues.

Docker vs Vagrant

Docker (Recommended for most cases):

Fast: Containers start in seconds
Resource-efficient: Run many instances simultaneously
CI-friendly: Works in most CI environments
Limitations: Cannot test kernel modules, systemd quirks, or anything requiring full VM

Vagrant (For complex scenarios):

Full VMs: Complete operating system
Systemd: Full init system support
Kernel testing: Can test kernel parameters and modules
Trade-offs: Slower (minutes to start), resource-heavy, harder in CI

When to use Vagrant:

# molecule/vagrant/molecule.yml
---
driver:
  name: vagrant
platforms:
  - name: ubuntu-vm
    box: ubuntu/jammy64
    memory: 2048
    cpus: 2
provisioner:
  name: ansible

Use Vagrant when testing roles that:

Modify kernel parameters (sysctl)
Require specific systemd features
Install kernel modules
Need full networking stack

Common Pitfalls

Container Limitations

Problem: Systemd doesn’t work properly in standard containers.

Solution: Use pre-built images with systemd support:

platforms:
  - name: instance
    image: geerlingguy/docker-ubuntu2204-ansible:latest
    volumes:
      - /sys/fs/cgroup:/sys/fs/cgroup:ro
    privileged: true
    command: /lib/systemd/systemd

Jeff Geerling’s Docker images are specifically built for Ansible testing with working systemd.

Privilege Issues

Problem: Tasks fail with permission errors.

Solution: Use become appropriately in your converge playbook:

# molecule/default/converge.yml
---
- name: Converge
  hosts: all
  become: true  # Run tasks with sudo
  tasks:
    - name: Include role
      include_role:
        name: nginx

Avoid requiring become: yes in the role itself when possible. Let the user decide privilege escalation.

Dependency Management

Problem: Role depends on other roles, but they’re not available during testing.

Solution: Define dependencies in meta/main.yml:

# meta/main.yml
---
dependencies:
  - role: geerlingguy.security
  - role: geerlingguy.firewall

Molecule automatically installs these before testing if you have the Galaxy dependency manager enabled:

# molecule/default/molecule.yml
dependency:
  name: galaxy
  options:
    role-file: requirements.yml

Create requirements.yml for external dependencies:

# requirements.yml
---
roles:
  - name: geerlingguy.security
    version: 2.3.0
  - name: geerlingguy.firewall
    version: 3.1.0

Test Flakiness

Problem: Tests occasionally fail for no apparent reason.

Common causes:

Network timeouts
Race conditions in service startup
Insufficient wait times

Solution: Add appropriate waits and retries:

- name: Wait for service to be ready
  ansible.builtin.wait_for:
    port: 80
    delay: 2
    timeout: 30

- name: Check endpoint with retry
  ansible.builtin.uri:
    url: http://localhost/health
  register: health_check
  until: health_check.status == 200
  retries: 5
  delay: 3

Tools and Integration

Testinfra for Verification

While Molecule uses Ansible for verification by default, you can also use Testinfra (Python-based testing):

pip install testinfra

molecule/default/tests/test_default.py:

import os
import testinfra.utils.ansible_runner

testinfra_hosts = testinfra.utils.ansible_runner.AnsibleRunner(
    os.environ['MOLECULE_INVENTORY_FILE']
).get_hosts('all')

def test_nginx_is_installed(host):
    nginx = host.package("nginx")
    assert nginx.is_installed

def test_nginx_running_and_enabled(host):
    nginx = host.service("nginx")
    assert nginx.is_running
    assert nginx.is_enabled

def test_nginx_listening(host):
    assert host.socket("tcp://0.0.0.0:80").is_listening

def test_index_html_content(host):
    content = host.file("/var/www/html/index.html").content_string
    assert "Deployed with Ansible" in content

Configure Testinfra in molecule.yml:

verifier:
  name: testinfra
  options:
    v: 1
