При попытке запустить тест Jest выдает неожиданную ошибку токена.Я использую ky http, который, очевидно, вызывает проблему, а не получает ее.
Test suite failed to run
Jest encountered an unexpected token
This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.
By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".
Here's what you can do:
• To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
• If you need a custom transformation specify a "transform" option in your config.
• If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.
You'll find more details and examples of these config options in the docs:
https://jestjs.io/docs/en/configuration.html

Вот мой package.json

При добавлении transform или transformIgnorePatterns в package.json, напримерэто:
"jest": {
"transform": {
"^.+\\.js$": "babel-jest"
},
"transformIgnorePatterns": [
"/node_modules/(?!(@ky)/).*/"
]
},
Я получаю эту ошибку:
Out of the box, Create React App only supports overriding these Jest options:
• collectCoverageFrom
• coverageReporters
• coverageThreshold
• globalSetup
• globalTeardown
• resetMocks
• resetModules
• snapshotSerializers
• watchPathIgnorePatterns.
These options in your package.json Jest configuration are not currently supported by Create React App:
• transform
• transformIgnorePatterns
If you wish to override other Jest options, you need to eject from the default setup. You can do so by running npm run eject but remember that this is a one-way operation. You may also file an issue with Create React App to discuss supporting more options out of the box.
У меня также есть babel.config.js, который пуст: atm:
module.exports = function () {
const presets = [];
const plugins = [];
return {
presets,
plugins
};
}
Извлечениене вариант.Я пытался решить это за + одну неделю.Любая помощь очень ценится.
