Background and Context

The test data in features/steps/message_router_new_coverage_steps.py is of poor quality. The tests rely on hardcoded data within the step definitions, which makes them brittle and difficult to maintain. This is part of a larger pattern of poor test data quality that has been observed in other step definition files across the project.

Improving test data quality in this file will make the test suite more robust, maintainable, and better at catching regressions across a wider range of scenarios.

Current Behavior

  • Test data is hardcoded directly within step definitions in features/steps/message_router_new_coverage_steps.py.
  • Scenarios in features/consolidated_routing.feature are tightly coupled to these hardcoded values.
  • Redundant scenarios exist that could be consolidated into scenario outlines, causing unnecessary code duplication.

Expected Behavior

  • Test data is externalized to fixture files (JSON or YAML) in the features/fixtures directory.
  • A data generation library (e.g., Faker) is used to produce more realistic and varied test data.
  • Redundant scenarios are consolidated into scenario outlines, reducing duplication and improving readability.

Acceptance Criteria

  • All hardcoded test data in features/steps/message_router_new_coverage_steps.py has been replaced with data loaded from external fixtures.
  • The tests in features/consolidated_routing.feature are updated to use the new fixtures.
  • The tests are more readable, maintainable, and cover a wider range of scenarios.
  • All nox stages pass.
  • Coverage >= 97%.

Supporting Information

  • Duplicate Check: Search queries "test data quality", "message_router_new_coverage_steps.py" — 0 results. No existing issues found related to test data quality in this specific file.
  • Related parent tracking issue: #3204
  • This issue follows the same pattern as other test-data-quality improvements in the project (e.g., #7844, #7787, #7800).

Backlog note: This issue was discovered during autonomous operation
on milestone v3.2.0. It does not block milestone completion and has been
placed in the backlog for human review and future milestone assignment.

Metadata

  • Branch: test/improve-test-data-quality-message-router-new-coverage-steps
  • Commit Message: test(features): improve test data quality in message_router_new_coverage_steps.py
  • Milestone: (backlog — no milestone assigned)
  • Parent Epic: #3204

Subtasks

  • Externalize test data to JSON or YAML files in the features/fixtures directory.
  • Use a data generation library (e.g., Faker) to create more realistic and varied test data.
  • Consolidate redundant scenarios into scenario outlines to reduce code duplication.
  • Update features/consolidated_routing.feature to use the new fixtures.
  • Run nox (all default sessions), fix any errors.
  • Verify coverage >= 97% via nox -s coverage_report.

Definition of Done

This issue is complete when:

  • All subtasks above are completed and checked off.
  • All hardcoded test data in features/steps/message_router_new_coverage_steps.py has been replaced with data loaded from external fixtures.
  • The tests in features/consolidated_routing.feature are updated to use the new fixtures.
  • The tests are more readable, maintainable, and cover a wider range of scenarios.
  • A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly, followed by a blank line, then additional lines providing relevant details about the implementation.
  • 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 before this issue is marked done.
  • All nox stages pass.
  • Coverage >= 97%.
