# Тестирование зависимостей с переопределениями { #testing-dependencies-with-overrides }

## Переопределение зависимостей во время тестирования { #overriding-dependencies-during-testing }

Есть сценарии, когда может понадобиться переопределить зависимость во время тестирования.

Вы не хотите, чтобы исходная зависимость выполнялась (и любые её подзависимости тоже).
