- tests/conftest.py: put repo root on sys.path so `import src...` resolves under pytest regardless of invocation directory. - test_matrix_formatting.py: lock in HTML formatted_body + plain-text fallback, URL linkification, HTML escaping, and send_alert field rendering. - test_station_persistence.py: cover default-load, save/reload round-trip (incl. Thai text), runtime-file precedence, and atomic-write cleanup. These are real assert-based tests (unlike the existing print-style scripts) so CI can gate on them. 13 tests, all passing.

"""Assert-based tests for station-mapping persistence.

|
|
Station CRUD must survive restarts: the scraper loads its mapping from a
|
|
runtime-writable JSON file (falling back to bundled defaults) and writes it back
|
|
atomically. These tests exercise that load/save behaviour without constructing a
|
|
full scraper (which would open network/DB connections).
