I used to maintain a number of [Ansible roles][roles], and I recently wrote one for automatically generating `settings.php` files for Drupal projects that I use for some client projects as part of the [Ansible and Ansistrano deployment process][talk], as it can populate these files with credentials stored in Ansible Vault.
I uploaded an initial version of the role [onto GitHub][github], but haven’t yet released it onto Ansible Galaxy.
I’d seen in other people’s roles and read elsewhere about writing automated tests for Ansible roles using a tool called [Molecule][molecule], and wanted to write some tests for this role before publishing it onto Galaxy.
I looked around for resources about Molecule, and found a [blog post by Jeff Geerling][jeff-post], but also this YouTube video that I found very helpful.
I’ve since been re-writing the role from scratch based on Molecule, and plan to release an official version of it soon.
