- test_fetch_cat.py: 10 тестов (def → async def, asyncio.run → await) - test_fetch_rss.py: 21 тест (def → async def, asyncio.run → await) - test_fetch_weather.py: 19 тест (def → async def, asyncio.run → await) - Удалён лишний import asyncio из тестовых файлов - Больше не создаётся новый event loop на каждый тест - RateLimiter (asyncio.Lock) теперь корректно работает в одном loop 230 тестов проходят.
