I need some help. I am trying to use Mocha for testing in a react/readux application. Unfortunately there seems to be a problem with compiling the code to es5, because I get this error:
Unexpected token (13:15)
11 | switch (action.type) {
12 | case types.ADD_USER:
> 13 | return { ...state, list: [ ...state.list, action.payload ] };
| ^
14 |
15 | case types.DELETE_USER:
16 | let deletedState = state.list.filter(user => user.id !== action.payload);
at Parser.pp$5.raise
I followed this blog entry closely to set-up the test environment: http://jamesknelson.com/testing-in-es6-with-mocha-and-babel-6/
Also, I created a .babelrc with this entries:
"presets": ["es2015", "react"]
This is my package.json:
{
"name": "react_frontend",
"version": "0.1.1",
"private": true,
"devDependencies": {

}
}
I absolutely have no idea what I did wrong. Any input is very welcome.
EDIT: I tried the solutions in the duplicate thread and installed the following packages:
chai-jquery babel-plugin-transform-object-rest-spread babel-preset-stage-2
and changed my .babelrc to
{
"presets": ["es2015", "react", "stage-2"],
"plugins": ["transform-object-rest-spread"]
}
I now get this error message when trying to run npm test:
global.document = _jsdom2.default.jsdom('<!doctype html><html><body></body></html>');
^
TypeError: _jsdom2.default.jsdom is not a function
at Object.<anonymous>
