cookie not getting read correctly from jest test in 4.0.2

[jonathanhculver]

Hello!

Opening in case other's have had the same issue. In 4.0.2 I have a jest test that set's a cookie and a function being tested that read's the cookie. The cookie comes back as undefined.

Downgrading to 4.0.0 fixes the issue for me.

Example:

// testFunc.js
import Cookies from 'universal-cookie';

const cookies = new Cookies();
const testFunc = () => (cookies.get('testCookie'));

// testFunc.spec.js
import Cookies from 'universal-cookie'
import testFunc from './testFunc';

const cookies = new Cookies();

test('testFunc', () => {
  cookies.set('testCookie', 'blah');
  // logging cookies.get('testCookie') correctly logs 'blah'

  const result = testFunc();
  expect(result).toEqual('blah'); // fails - result is actually `undefined`
});

Hello @jonathanhculver! I'm having the same issue that you're having. Looking through the source code, I believe I found the root of the problem.

Seen here

the DOCUMENT_HAS_COOKIE is initialized as false in versions greater than 4.0.0.

Setting this value to true in both the .js file and test file seems to fix this issue. But I would just stick with the 4.0.0 version until it can get fixed :D

Fixed with v4.0.3

For me I think while testing I had to wrap the component with CookieProvider fixed it
