(TypeScript -> Gulp, Browserify, Babel -> Javascript -> Cypress)
Когда я запускаю свои кипарисовые тесты, процент покрытия кода неверен, потому что он включает каталог node_modules. Все, что я хочу сделать, это исключить node_modules из моего покрытия кода, чтобы покрытие было неправильным .
Я запускаю команду npm run test:coverage (см. Мой пакет json ниже) для выполнения всех необходимых шагов.
