Extra vars

The extra_vars flag will override default variables when executing a task. This allows to change variable in the context of a scenario to validate a playbook behavior.

Syntax

monkeyble_scenarios:
  validate_test_1:
    name: "Monkeyble hello world"
    tasks_to_test:
      - task: "debug task"    
        extra_vars:
          new_var_key: "new_value"     
          override_existing_key: "other value"     

Example

# playbook.yml
- name: "play1"
  hosts: localhost
  connection: local
  gather_facts: false
  become: false
  vars:
    my_var: "Hello Monkeyble"
  tasks:
    - name: "task1"
      debug:
        msg: "{{ my_var }}"

    - name: "task2"
      debug:
        msg: "{{ my_var }}"

# monkeyble.yml
monkeyble_scenarios:
  validate_test_1:
    name: "Monkeyble hello world"
    tasks_to_test:
      - task: "task2"
        extra_vars:
          my_var: "new value"

When executed, the second task use the overriden variable value instead of the default one set at playbook level:
