Как добавить приложение Jest в React, созданное на Parcel.js

У меня есть приложение React, созданное с использованием parcel.js. Я добавил Jest и пытаюсь запустить базовый тест, но похоже, что код не преобразуется перед запуском теста Jest encountered an unexpected token.

Я не уверен, что часть Parcel.js - отвлекающий маневр, но это немного отличается от приведенных здесь примеров.
