  • Branch: test/backlog-fixture-management
  • Commit Message: test(fixtures): create reusable fixture library for complex test objects
  • Milestone: Backlog (no milestone — see note below)
  • Parent Epic: #3374

Background and Context

Our tests for complex objects, such as the v3 Plan, rely on ad-hoc fixture creation within the step definitions. This makes it difficult to reuse fixtures across different tests and to ensure that the fixtures are consistent.

A test fixture is a fixed state of a set of objects used as a baseline for running tests. The purpose of a test fixture is to ensure that there is a well-known and fixed environment in which tests are run so that results are repeatable.

Currently, fixture data is scattered across individual step definition files, leading to:

  • Duplication of fixture setup logic across test suites
  • Inconsistent fixture states that can cause flaky or misleading test results
  • Difficulty onboarding new contributors who must understand each test's bespoke setup

Implementation Plan

  1. Identify all complex objects that are used as fixtures in our tests (e.g., v3 Plan, sessions, actors, tools).
  2. For each identified object, create a library of pre-defined fixtures that can be easily reused across different tests.
  3. Update the existing tests to use the new fixture library.
  4. Document the fixture library so contributors know how to extend it.

Subtasks

  • Audit all existing BDD step definitions and identify ad-hoc fixture creation patterns
  • Design a tests/fixtures/ library structure (e.g., plan_fixtures.py, session_fixtures.py, actor_fixtures.py)
  • Implement pre-defined fixture factories for all identified complex objects
  • Refactor existing step definitions to import and use the new fixture library
  • Add documentation / docstrings to the fixture library
  • Run nox (all default sessions), fix any errors
  • Verify coverage >= 97% via nox -s coverage_report

Definition of Done

  • All subtasks above are completed and checked off
  • A fixture library exists under tests/fixtures/ covering all complex objects used as test baselines
  • All existing tests have been updated to use the new fixture library (no ad-hoc fixture creation in step definitions)
  • Tests are still passing after the refactor
  • A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly
  • The commit is pushed to the remote on the branch matching the Branch in Metadata exactly
  • The commit is submitted as a pull request to master, reviewed, and merged
  • All nox stages pass
  • Coverage >= 97%

Backlog note: This issue was discovered during autonomous operation
on milestone v3.6.0. It does not block milestone completion and has been
placed in the backlog for human review and future milestone assignment.
