Gain access to role vars in Goss test files

[decentral1se]

Transferring https://github.com/ansible/molecule/issues/2375 to here.

---

We need to pass the role defaults/main.yml and vars/main.yml into the verifier (like goss). If I have in my defaults/main.yml:

---
myfile: /etc/foo

And then a Goss test like:

---
file:
    /etc/foo:
        exists: true

My tests and my vars can quickly get out of sync when I change my vars.

How can we receive vars from Ansible in the context of Molecule?

I have been using j2cli for this purpose. Since I want to use the goss test anyway in production, I have it as a template and the vars in default/main.yml

I can then update my development goss tests by running (e.g. in nginx role)

j2 --customize ~/custom-j2.py templates/test_nginx.yml.j2 defaults/main.yml > molecule/default/tests/test_default.yml

We just need to adapt j2cli to the ansible jinja2 config

# custom-j2.py
def j2_environment_params():
    """ Extra parameters for the Jinja2 Environment """
    # Jinja2 Environment configuration
    # http://jinja.pocoo.org/docs/2.10/api/#jinja2.Environment
    return dict(
        # Remove whitespace around blocks
        trim_blocks=True,
    )

Does this somehow help? Can it be integrated into molecule?

@t2d have you got a working example on Github that we can take a look at please ?

Would it be a good idea to put a verifier task as a yml file inside role tasks? Then you can execute it with molecule verify.yml. In that way you could access inventory and role vars. Also run it in other deployments.

@decentral1se I think it's possible this request was addressed by @markwell-ch via PR #13

Can you verify?

Awesome, that works like a charm! https://github.com/systemli/ansible-role-sshd/commit/abc61369364d42416e4958d18da6e705985250d0 Thanks @markwell-ch !
