"""Offline unit tests for run_domclick_city_sweep orchestration (JSON API rewrite).
|
||
|
||
Pure & fast: NO live network, NO DB.
|
||
|
||
Coverage:
|
||
- fetch_city вызывается, save_listings получает lots с source='domklik'
|
||
- DomClickCitySweepCounters корректно заполняется
|
||
- Cooperative cancel прерывает sweep перед SERP
|
||
- fetch_city exception → errors_count++; 0 lots + errors → mark_failed (#1968)
|
||
- Успешный sweep (lots > 0) → mark_done
|
||
- Пустой SERP (0 lots, 0 errors) → mark_done (не ошибка)
|
||
- DomClickBlockedError в фазе → errors_count++; 0 lots → mark_failed
