How to make mandatory variables if variable is defined

[Javier Martí]

Hi, I want to make sure before execution of the role that if a variable is defined you have to define another variables, can I do that?

I have a template:

{% if variable1 != '' %}

variable1 = {{ variable1 }}

variable2 = {{ variable2 }}

variable3 = {{ variable3 }}

{% endif %}

How to make mandatory variable2 and variable3 if variable1 is defined?

- assert:
that:
- variable2 is defined
- variable3 is defined
when: variable1 is defined
