«Jest обнаружил неожиданный токен», когда я тестировал реагирующий компонент. Я застрял на нем с 5 дней

Question

Я застрял на нем с 5 дней. Я получаю сообщение об ошибке «Jest обнаружил неожиданный токен». Я пробовал все предоставленные решения, соответствующие этому. Никто из них не работал для меня. Ошибка

import MyNavbar from '../../components/MyNavbar'
      5 | test("Should return MyNavbar component", () => {
    > 6 |     const wrapper = shallow(<MyNavbar />)
        |                             ^
      7 |     expect(wrapper.find('.navbar-brand').find('kbd').text()).toBe("Expensify")

Мой .babelr c файл

{
     "env": {
         "development": {
             "presets": ["env", "react"],
             "plugins": ["transform-object-rest-spread", "transform-class-properties"]
         },
         "test": {
             "presets": [
                 ["env", {
                     "targets": {
                         "node": "current"
                     }
                 }, "react"]
             ],
             "plugins": ["@babel/plugin-proposal-object-rest-spread", "transform-class-properties"]
         }
     }
 }
