Also, we're still on 3.10 on the machine, so I'd like to see the tests for that version back to have a certain degree it's not broken when deploying.

Added Python 3.10 back to the test matrix in commit 818bdec. CI should now run tests on 3.10, 3.12, 3.13, and 3.14.

fix(pygithub): Add empty token guards for PyGithub 2.x compatibility
fbcc43b 
PyGithub 2.x now asserts that tokens must be non-empty when creating
Auth.Token objects. This caused test failures and runtime errors when
GITHUB_TOKEN was not configured.

Added guards before all Github(auth=Auth.Token(...)) calls:
- mod_customized/controllers.py: Skip commit fetching if token empty
- mod_ci/controllers.py: Return error/skip GitHub operations if token empty
  - Webhook handler: Return 500 JSON error
  - Progress update: Log error and return early
  - PR comment: Log error and return FAILURE status
  - Block user: Log error and redirect

fix(tests): Fix async mock issues and update Python version requirements
9bbeb2a 
- Update CI to use Python 3.12 (required), 3.13, 3.14 (experimental)
- Drop support for Python 3.9, 3.10, 3.11
- Fix async mock issues in tests by explicitly configuring MagicMock chains
  - test_data_for_test: Configure mock_g.db.query chain
  - test_gcp_instance: Configure mock_g.db.query chain
  - test_start_test: Configure mock_g.db.query chain
  - test_finish_type_request tests: Configure mock_rt.query chain

In Python 3.8+, MagicMock can return AsyncMock objects for certain access
patterns, causing 'coroutine' object attribute errors. The fix explicitly
configures return values to be regular MagicMock objects.

fix(tests): Fix deprecated assertEquals and async mock issues
2a3c388 
- Replace assertEquals with assertEqual (deprecated in Python 3.12+)
  - tests/test_config_parser.py: test_parse_config
  - tests/test_run.py: test_load_secret_keys_*

- Explicitly set mock_g.db = MagicMock() to prevent AsyncMock behavior
  - test_data_for_test
  - test_start_test
  - test_gcp_instance

In Python 3.8+, MagicMock auto-creates child mocks which can become
AsyncMock objects. By explicitly setting mock_g.db = MagicMock(), we
ensure the entire mock chain uses regular MagicMock behavior.

test: Improve test coverage and reduce code duplication
774189b 
- Add helper functions in tests/base.py:
  - create_mock_db_query(): Reduces duplicated mock db setup code
  - create_mock_regression_test(): Reduces duplicated regression test mock setup

- Add tests for empty GitHub token scenarios:
  - test_start_ci_empty_token: Tests 500 response when token missing
  - test_comment_pr_empty_token: Tests FAILURE status when token missing
  - test_cron_job_empty_token: Tests early return when token missing
  - test_process_empty_github_token: Tests error flash when token missing
  - Update test_customize_test_page_without_github_token to cover elif branch

- Refactor existing tests to use new helper functions, reducing duplication

This improves codecov patch coverage and reduces SonarCloud duplication
by consolidating repeated mock setup patterns into reusable helpers.

fix(tests): Use real g.db instead of mock for db query tests
b16417a 
The tests from PR #943 passed mock_g.db to functions that internally
call db.query().filter(), but the mock chain wasn't properly set up.
In Python 3.10+, this causes 'coroutine' object has no attribute 'filter'
errors.

Since these tests are testing exception handling (GithubException,
timeout, HTTP errors), not database interactions, use the real g.db
instead of the mock.
