## [Example Playbook](#example-playbook)
|
|
|
|
This example is taken from `molecule/resources/converge.yml` and is tested on each push, pull request and release.
|
|
```yaml
|
|
---
|
|
- name: Converge
|
|
hosts: all
|
|
become: yes
|
|
gather_facts: yes
|
|
|
|
roles:
|
|
- role: robertdebock.common
|
|
```
|
|
|
|
The machine may need to be prepared using `molecule/resources/prepare.yml`:
|
|
```yaml
|
|
---
|
|
- name: Prepare
|
|
hosts: all
|
|
gather_facts: no
|
|
become: yes
|
|
|
|
roles:
|
|
- role: robertdebock.bootstrap
|
|
```
|
|
|
|
For verification `molecule/resources/verify.yml` runs after the role has been applied.
|
|
```yaml
|
|
---
|
|
- name: Verify
|
|
hosts: all
|
|
become: yes
|
|
gather_facts: no
|
|
|
|
tasks:
|
|
- name: check if connection still works
|
|
ping:
|
|
```
|
|
|

|
|
|
|
## [Testing](#testing)
|
|
|
|
[Unit tests](https://travis-ci.com/robertdebock/ansible-role-common) are done on every commit, pull request, release and periodically.
|
|
|
|
If you find issues, please register them in [GitHub](https://github.com/robertdebock/ansible-role-common/issues)
|
|
|
|
Testing is done using [Tox](https://tox.readthedocs.io/en/latest/) and [Molecule](https://github.com/ansible/molecule):
|
|
|
|
[Tox](https://tox.readthedocs.io/en/latest/) tests multiple ansible versions.
|
|
[Molecule](https://github.com/ansible/molecule) tests multiple distributions.
|
|
|
|
To test using the defaults (any installed ansible version, namespace: `robertdebock`, image: `fedora`, tag: `latest`):
|
|
|
|
```
|
|
molecule test
|
|
|
|
# Or select a specific image:
|
|
image=ubuntu molecule test
|
|
# Or select a specific image and a specific tag:
|
|
image="debian" tag="stable" tox
|
|
```
|
|
|
|
Or you can test multiple versions of Ansible, and select images:
|
|
Tox allows multiple versions of Ansible to be tested. To run the default (namespace: `robertdebock`, image: `fedora`, tag: `latest`) tests:
|
|
|
|
```
|
|
tox
|
|
|
|
# To run CentOS (namespace: `robertdebock`, tag: `latest`)
|
|
image="centos" tox
|
|
# Or customize more:
|
|
image="debian" tag="stable" tox
|
|
```
