vue spinner causing jest tests to fail
Maseline opened this issue · comments
What's the right way to configure jest when using vue-spinner package. After adding the package, tests fail with this:
` 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`
Tried the suggestions there but no success. My current jest config file:
{ "preset": "jest-puppeteer", "testRegex": "./new-e2e/.*.js$" }
I have the same issue running Vue 2.7 with Jest 27
console.error
[Vue warn]: Failed to resolve async component: function PulseLoader() {
return Promise.resolve().then(function () {
return (0, _interopRequireWildcard2.default)(require('vue-spinner/src/PulseLoader.vue'));
});
}
Reason: SyntaxError: Unexpected token '<'

I ended up mocking the component for the time being since it's not really useful for the test case I needed. At least this won't be a blocker if you want to test your component.
jest.mock('vue-spinner/src/PulseLoader.vue', () => ({
render: (h) => h('div', 'PulseLoader'),
}))
