Можно ли использовать карма-покрытие с посылкой? Я получаю 0% покрытие, хотя тесты проходят успешно

0 голосов
/ 02 августа 2020

У меня есть набор юнит-тестов Mocha + Chai. Они успешно работают на странице HTML, а также в Карме (с использованием Headless Chrome). Классы определены в различных файлах, и соответствующие файлы включаются в тесты с использованием require, затем используется пакет Parcel. Все это работает, и тесты проходят.

Теперь я хотел бы добавить покрытие, используя karma-coverage. Я использую конфигурацию ниже, но, как видно из журнала внизу, охват составляет 0% для каждого файла, несмотря на прохождение тестов.

Я просмотрел множество руководств и отчетов об ошибках, но ни одного такого используйте комбинацию karma-coverage и karma-parcel. Интересно, есть ли где-нибудь проблема с инструментами и объединением кода. Кажется, что karma-parcel не поддерживает обслуживание исходных карт . Вызовет ли это проблему?

Я также пробовал инструментировать код, используя babel-plugin-istanbul вместо препроцессора karma-coverage, но это тоже не сработало.

Является ли комбинация karma-coverage и посылка возможна?
