Cross origin null forbidden: Axios tries to make an xhr request in a Node environment, instead of an http request.

Axios tries to make an xhr request in a Node environment, instead of an http request.

// It doesn't work

import axios from 'axios';

const { data } = await axios.get( 'http://example.com' );


// It work

import axios from 'axios';
import adapter from 'axios/lib/adapters/http';

const { data } = await axios.get( 'http://example.com', { adapter } );

It’s a issue due to Jest default environment. https://facebook.github.io/jest/docs/en/configuration.html#testenvironment-string

The test environment that will be used for testing. The default environment in Jest is a browser-like environment through jsdom. If you are building a node service, you can use the node option to use a node-like environment instead.

What creates XMLHttpRequest and misleads this function: https://github.com/axios/axios/blob/9a6abd789f91a87d701116c0d86f1cfbc3295d66/lib/defaults.js#L16-L26

To fix this I had to add this in my jest.config.js file:

{
  // ...
  testEnvironment: 'node'
  // ...
}
