# ``tests/ansible`` Directory
This is an an organically growing collection of integration and regression
tests used for development and end-user bug reports.
It will be tidied up over time, meanwhile, the playbooks here are a useful
demonstrator for what does and doesn't work.

## Preparation
For OS X, run the ``osx_setup.yml`` script to create a bunch of users.
## ``run_ansible_playbook.sh``
This is necessary to set some environment variables used by future tests, as
there appears to be no better way to inject them into the top-level process
environment before the Mitogen connection process forks.
## Running Everything
```
ANSIBLE_STRATEGY=mitogen_linear ./run_ansible_playbook.sh all.yml
```
## ``hosts/`` and ``common-hosts``
To support running the tests against a dev machine that has the requisite user
accounts, the the default inventory is a directory containing a 'localhost'
file that defines 'localhost' to be named 'target' in Ansible inventory, and a
symlink to 'common-hosts', which defines additional targets that all derive
from 'target'.
This allows ``ansible_tests.sh`` to reuse the common-hosts definitions while
replacing localhost as the test target by creating a new directory that
similarly symlinks in common-hosts.
There may be a better solution for this, but it works fine for now.
