05.12.2024 12:18При така дефинираните тестове (да вземем първия), имаш следния flow:
1. Функцията бива извикана.
2. Вътре в нея се отваря някакъв файл, както ти правилно си отгатнала.
3. Файлът се чете и, тъй като е mock-нат, прочита `"This recipe is valid because it contains fish."`.
4. Функцията прави някакви други проверки, които съответстват на условието.
С така подаденият стринг - очакваш ли функцията да върне `True`?
