The role gathers the facts it uses. For example, if the user uses
ANSIBLE_GATHERING=explicit, the role uses the setup module with the
facts and subsets it requires.

This change allows us to test this. Before every role invocation, the test
will use meta: clear_facts so that the role starts with no facts.

Create a task file tests/tasks/run_role_with_clear_facts.yml to do the tasks
to clear the facts and run the role. Note that this means we don't need to
use gather_facts for the tests.

Some vars defined using ansible_facts have been changed to be defined with
set_fact instead. This is because of the fact that vars are lazily
evaluated - the var might be referenced when the facts have been cleared, and
will issue an error like ansible_facts["distribution"] is undefined. This is
typically done for blocks that have a when condition that uses ansible_facts
and the block has a role invocation using run_role_with_clear_facts.yml
These have been rewritten to define the when condition using set_fact. This
is because the when condition is evaluated every time a task is invoked in the
block, and if the facts are cleared, this will raise an undefined variable error.

Summary by Sourcery

Tests:

  • Replace direct include_role usages in ad_integration tests with a helper task file that clears facts then runs the role, allowing verification that the role works without pre-gathered facts.

…s before include_role

The role gathers the facts it uses.  For example, if the user uses
`ANSIBLE_GATHERING=explicit`, the role uses the `setup` module with the
facts and subsets it requires.

This change allows us to test this.  Before every role invocation, the test
will use `meta: clear_facts` so that the role starts with no facts.

Create a task file tests/tasks/run_role_with_clear_facts.yml to do the tasks
to clear the facts and run the role.  Note that this means we don't need to
use `gather_facts` for the tests.

Some vars defined using `ansible_facts` have been changed to be defined with

Reviewer's Guide

Adds a reusable test task wrapper that clears Ansible facts before running the ad_integration role, then refactors existing tests to use it instead of including the role directly and removes now-unnecessary gather_facts usage.

File-Level Changes

Change Details Files
Introduce shared test helper that clears facts then runs the ad_integration role, with optional control over tasks_from, public vars export, and failure handling.
  • Create tests/tasks/run_role_with_clear_facts.yml that first executes meta: clear_facts, then conditionally runs the ad_integration role in a block that swallows failures when __sr_failed_when is false, and finally runs the role normally when __sr_failed_when is true or undefined.
  • Provide parameters __sr_tasks_from, __sr_public, and __sr_failed_when to mimic include_role options and control which tasks file is used, whether role vars are public, and whether failures are ignored.
tests/tasks/run_role_with_clear_facts.yml
Refactor tests to use the new clear-facts helper instead of including the role directly and remove explicit gather_facts from affected playbooks.
  • Replace include_role: linux-system-roles.ad_integration in test playbooks with include_tasks: tasks/run_role_with_clear_facts.yml, passing __sr_public: true where tests relied on role variables being public.
  • Remove gather_facts directives from multiple test plays since the role is now responsible for gathering any facts it needs via setup.
  • Ensure repeated role invocations in tests (e.g., rerun to remove vars, migrate settings, manage packages) all go through the new helper so that each run starts from a clean fact set.
