How to debug your tests when using testinfra as verifier in Molecule

Question

When testing an ansible role using molecule tool and verifying the result with testinfra(pytest), I am not able to print or debug certain output or an ansible variable.

============================= test session starts ==============================
platform linux2 -- Python 2.7.5, pytest-4.6.6, py-1.8.0, pluggy-0.13.0 -- /root/test1/myenv/bin/python2

tests/test_default.py::test_Ansible_variable[ansible://instance] PASSED  [100%]

=========================== 1 passed in 3.29 seconds ===========================

Is there is a way to do that?

Answer 1

Under the testinfra verifier component in molecule.yml file, enable the 's' option. For example:

---
dependency:
  name: galaxy
driver:
  name: docker
lint:
  name: yamllint
platforms:
  - name: instance
    image: centos:7
provisioner:
  name: ansible
  lint:
    name: ansible-lint
verifier:
  name: testinfra
  lint:
    name: flake8
  options:
    s: true
