  • Commit Message: test(fixtures): expand test data variety to cover edge cases in feature files
  • Milestone: (backlog — see note below)
  • Parent Epic: #5407

Background and context

Our current test data is often simplistic and focuses on the "happy path." To improve the robustness of our test suite, we should expand the variety of our test data to include more edge cases. This will help us catch bugs that might only occur with specific data inputs.

This can be achieved by:

  • Adding new scenarios to our feature files that use different data.
  • Using Gherkin's Examples tables to run the same scenario with multiple data inputs.
  • Adding more step definitions that create data with edge-case values (e.g., empty strings, very long strings, non-ASCII characters, null values).

Expected behavior

The test suite should exercise edge-case data inputs across critical areas of the codebase, ensuring that behaviors with unusual or boundary data are verified and regressions are caught early.

Acceptance criteria

  • At least three critical areas are identified where test data variety is lacking.
  • New Gherkin scenarios or Examples tables are added for each identified area.
  • Step definitions are implemented to generate edge-case test data (empty strings, very long strings, non-ASCII characters, null/None values, boundary integers, etc.).
  • All new scenarios pass CI.

Subtasks

  • Identify at least three critical areas where test data variety is lacking (e.g., domain model fields, CLI input parsing, serialization/deserialization).
  • Add new scenarios or Examples tables to the relevant .feature files to cover these areas.
  • Implement the corresponding step definitions under features/steps/ to generate the new edge-case test data.
  • Tests (Behave): Verify all new scenarios pass with nox -s unit_tests.
  • Tests (Robot): Add or update integration tests if edge-case data affects integration boundaries.
  • Verify coverage >=97% via nox -s coverage_report.
  • Run nox (all default sessions), fix any errors.

Definition of Done

This issue is complete when:

  • At least three critical areas are identified and have their test data variety expanded.
  • New tests are added that cover edge cases for these areas.
  • All new and existing tests pass CI.
  • Coverage remains at or above 97%.
  • All nox stages pass.
  • A PR has been submitted, reviewed, and merged to master.

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