How to disable Molecule idempotence check on Ansible role test?

Question

Using Molecule v.2 to test Ansible roles, I faced an issue with the check for a role to be idempotent.

How can I disable this check?

As documented, Molecule configuration parameters are required to be set in molecule.yml file, but I could not find how to disable idempotence check.

# Probably something like below should disable idempotency check.
  idempotent: false
# Uncomment when developing locally to 
# keep instances running when tests are completed. 
# Must be kept commented when building on CI/CD.  
#  test_sequence:
#    - destroy
#    - create
#    - converge
#    - lint
#    - verify

I want to get rid of idempotency check altogether and rely on my own tests.

Answer 1

You should uncomment the test_sequence and include only the tests you want, for example:

test_sequence:
  - destroy
  - create
  - converge
  # - idempotence
  - lint
  - verify
