Я пытаюсь провести модульное тестирование моего компонента React, который импортирует другой компонент, содержащий файл .png. Из-за этого изображения мои тестовые костюмы не работают. Я попробовал все возможные решения с конфигурацией ниже, но все равно не повезло.
Пожалуйста, предложите, это моя конфигурация проекта.
Это мой jest.config. json

"testRegex": "((\\.|/*.)(spec))\\.js?$"

resolve: {

output: {

filename: 'bundle.js',
publicPath: '/',
},
plugins: [new webpack.HotModuleReplacementPlugin()],
devServer: {
contentBase: './dist',
hot: true,
},
};
Мой .babelr c файл
{
"presets": ["@babel/preset-env", "@babel/preset-react"]
}
Наконец, мой тестовый файл:
import React from 'react';
import Enzyme, { shallow, mount } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';
import MyPackage from '../Components/index';
Enzyme.configure({ adapter: new Adapter() });
describe('Some name', () => {
it('This should be loaded', () => {
const wrapper = shallow(<MyPackage />);
const x= wrapper.find('#selector').debug();
expect(x.prop('length')).toBe(1);
});
});
Я попытался добавить mocks / fileMock. js с
export default '';
и mocks / styleMocks. js
module.exports = {};
все еще вижу эту ошибку -
● Test suite failed to run
D:\ReactStuff\folder\myproject\src\assets\images\mylogo.png:1

5 | return (
Что мне здесь не хватает. Пожалуйста, предложите
