Jest es6 modules: unexpected module import
I’m trying to test a file which needs to import an es6 module like this:
It seems I’m missing some configurations to make it work properly.
If you can achieve this with another unit testing framework easily, I’m interested too.
Thank you in advance for your help.
- Install required dependencies:
yarn add --dev babel-jest @babel/core @babel/preset-env
or
npm install --save-dev babel-jest @babel/core @babel/preset-env
- Create
babel.config.jsin your main folder and paste it there:
// babel.config.js
module.exports = {
presets: [
[
'@babel/preset-env',
{
targets: {
node: 'current',
},
},
],
],
};
- Make sure all your jest settings in
package.jsonandjest.config.jsare set to default.
As node does not support modules you have to compile your files using Babel. Have a look at the docs on how to configure Jest and Babel
