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

Run the trustee_attestation_client role in tests via a shared task file that clears facts before each role invocation.

Tests:

  • Introduce a reusable tasks file that clears Ansible facts and then runs the trustee_attestation_client role for tests.
  • Update existing test playbooks to use the new tasks file instead of direct role inclusion or gather_facts, ensuring the role runs 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
`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

Reviewer's Guide

Tests now execute the trustee_attestation_client role via a shared task file that first clears Ansible facts, ensuring the role gathers all required facts itself and supporting conditional failure handling via __sr_failed_when and optional public variable export.

File-Level Changes

Change Details Files
Route all trustee_attestation_client test playbooks through a shared helper task that clears facts, then runs the role.
  • Replace direct role usage in test playbooks with include_tasks of a new helper task file.
  • Remove gather_facts settings from tests since facts are now cleared explicitly before role execution.
  • Propagate __sr_public and other role-related vars via the helper include where necessary.
tests/tests_default.yml
tests/tests_kbs_config.yml
tests/tests_secret_registration_client.yml
tests/tests_encrypt_disk.yml
tests/tests_trustee_gc_disabled.yml
tests/tests_include_vars_from_parent.yml
Introduce tests/tasks/run_role_with_clear_facts.yml to centralize fact-clearing and role invocation behavior for tests.
  • Add a meta: clear_facts task to ensure the role starts with no gathered facts.
  • Wrap include_role invocation in a conditional block that simulates include_role failed_when=false behavior using __sr_failed_when.
  • Support configurable tasks_from selection and public variable export using __sr_tasks_from and __sr_public, with sensible defaults for normal runs.
