Create new test.yml workflow to run backend pytest tests with coverage reporting. Leverages existing pytest.ini config for coverage settings. Adds MishaKav/pytest-coverage-comment to post coverage summary as PR comment with per-file breakdown.

Purpose

This pull request introduces a new GitHub Actions workflow to automate backend testing and coverage reporting for the Python backend API. The workflow is triggered on pushes and pull requests to key branches and only runs when relevant backend files are changed. It installs dependencies, checks for the presence of test files, runs tests with coverage, and posts coverage results as a comment on pull requests.

CI/CD automation for backend testing:

  • Added .github/workflows/test.yml to define a workflow that runs backend tests with coverage on pushes and pull requests to main, dev, and demo branches when backend files change.
  • Configured the workflow to install Python 3.12, dependencies, and conditionally run tests only if test files exist, improving efficiency and avoiding unnecessary runs.

Automated test coverage reporting:

  • Integrated the pytest-coverage-comment GitHub Action to automatically post coverage results as a comment on pull requests, but only when tests are executed and the PR is not from a fork.

Does this introduce a breaking change?

  • Yes
  • No

- Remove demo branch from workflow triggers
- Fix dependency install: use pip install -e . with explicit
  pytest install since pyproject.toml uses dependency-groups
  (PEP 735) which pip does not support

The pytest.ini file uses TOML format ([tool.pytest.ini_options]) but is
named .ini, causing pytest parse errors. Pass all coverage flags explicitly
and use -c /dev/null to bypass the broken config file.

When using -c /dev/null to bypass malformed pytest.ini, pytest sets its
rootdir to /dev/ and discovers unrelated test files. Adding --rootdir=.
keeps test discovery scoped to the backend-api directory.

The bypassed pytest.ini had pythonpath configuration pointing to src/.
Tests import from 'libs' and 'routers' which live under src/backend-api/src/.
Setting PYTHONPATH=src resolves the ModuleNotFoundError for these imports.

The libs/ and routers/ modules live under src/backend-api/src/app/, not
src/backend-api/src/. Updated PYTHONPATH and --cov path accordingly.

- Import FileInfo from routers.models.files (was routers.model.model_process)
- Import enlist_process_queue_response from routers.models.processes
- Add required user_id parameter to all enlist_process_queue_response calls

The routers/model/ module was renamed to routers/models/ but the test
imports were not updated, causing ModuleNotFoundError during collection.

The test creates FileInfo from files.py (with content field) but
enlist_process_queue_response expects FileInfo from processes.py (different
model). Converting via model_dump() resolves Pydantic type validation.

- Rename get_typed_service() to get_service() in DI tests to match
  current AppContext API (8 failures)
- Update config tests to expect default 'Hello World!' value instead of
  App Configuration Store value that requires Azure connection (2 failures)

app_logging_enable defaults to False (not True), azure_package_logging_level
defaults to 'WARNING' (not 'INFO'), azure_logging_packages defaults to None
(not []).
