Commit message: test(fixtures): improve BDD test data quality with realistic, separated, and generated data
Branch name: feat/test-infra/improve-test-data-quality

Background and Context

The current test data for the BDD tests in the features/fixtures directory is overly simplistic and not representative of real-world scenarios. The data, such as file content in git_repo.json, uses "hello world" style examples. This is sufficient for basic functionality testing but does not cover edge cases or complex scenarios that the system is likely to encounter in production.

Additionally, embedding file content directly within JSON fixtures makes the test data difficult to maintain, especially for larger files or non-text files.

This issue was identified by the Test Infrastructure Pool Supervisor ([AUTO-INF-SUP] #8470) as part of the broader CI/test infrastructure improvement effort tracked under Epic #5407.

Expected Behavior

BDD test fixtures in features/fixtures/ contain realistic, complex test data representative of real-world usage.
File content is stored in separate files rather than embedded directly in JSON fixtures.
A data generation library (e.g., Faker) is used where appropriate to produce realistic test data on the fly.
Tests exercise edge cases such as files with unusual characters, large files, and multiple programming languages.
Test data is easy to maintain and extend.

Acceptance Criteria

Existing simplistic fixture data (e.g., git_repo.json) is replaced with realistic, multi-language code examples covering edge cases.
File content is extracted from JSON fixtures into separate files; JSON fixtures reference these files by path.
At least one BDD scenario uses Faker (or equivalent) to generate realistic test data dynamically.
All existing BDD tests continue to pass after the fixture refactor.
New or updated fixtures cover at least: files with unusual characters, a file >1KB, and files in ≥2 programming languages.
Test coverage remains ≥97% as verified by nox -s coverage_report.
nox (all default sessions) passes without errors.

Subtasks

Audit all fixture files in features/fixtures/ and identify simplistic or embedded content.
Design a directory structure for separated fixture data files (e.g., features/fixtures/data/).
Replace "hello world" style content in git_repo.json (and similar) with realistic code samples in multiple languages.
Extract embedded file content from JSON fixtures into standalone files; update fixture references accordingly.
Add edge-case fixture files: file with unusual/unicode characters, file >1KB, binary-adjacent content.
Integrate Faker (or equivalent) into the BDD step definitions for dynamic data generation where appropriate.
Update any step definitions or hooks that load fixture data to support the new file-reference format.
Run the full BDD suite (nox -s bdd or equivalent) and confirm all scenarios pass.
Run nox -s coverage_report and confirm coverage ≥97%.
Run nox (all default sessions) and fix any errors.

Definition of Done

This issue is complete when:

All subtasks above are completed and checked off.
All fixture files in features/fixtures/ use realistic, representative data with no "hello world" placeholders.
File content is stored in separate files and referenced from JSON fixtures — no large embedded strings in JSON.
At least one scenario uses dynamically generated data via Faker or equivalent.
All BDD tests pass via the project task runner.
Test coverage meets or exceeds 97% as verified by nox -s coverage_report.
A single Git commit is created where the first line of the commit message is exactly:
```
test(fixtures): improve BDD test data quality with realistic, separated, and generated data
```
followed by a blank line and additional lines describing the changes made.
The commit is pushed to the remote on the branch feat/test-infra/improve-test-data-quality.
The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked complete.
The issue is transitioned to State/Completed after the PR is merged.

[AUTO-OWNR-2] Triage Decision (Cycle 3)

Status: ✅ Verified

MoSCoW: Should Have
Priority: Medium

Rationale: Improving BDD test data quality from "hello world" placeholders to realistic, multi-language, edge-case fixtures is a valid and valuable test infrastructure task. It improves test fidelity and maintainability without being a hard blocker for milestone acceptance. MoSCoW/Should Have and Priority/Medium are confirmed as appropriate — this is important work but does not gate any milestone directly. Labels unchanged from initial assessment.

Next Steps: A developer should pick up branch feat/test-infra/improve-test-data-quality, audit all fixtures in features/fixtures/, replace simplistic content with realistic multi-language code samples, extract embedded file content into separate files, integrate Faker for dynamic data generation in at least one scenario, and verify the full BDD suite passes with coverage ≥ 97%.
