Jest and Upgrading to 2.90

[maitriyogin]

Hi,
I just updated expo to the latest 2.90, after running tests I get the following:

ReferenceError: self is not defined

      at node_modules/whatwg-fetch/dist/fetch.umd.js:8:40
      at Object.<anonymous>.support.searchParams (node_modules/whatwg-fetch/dist/fetch.umd.js:2:66)
      at Object.<anonymous> (node_modules/whatwg-fetch/dist/fetch.umd.js:5:2)
      at Object.<anonymous> (node_modules/jest-expo/src/setup.js:7:47)

This is definitely a problem with expo but was wondering if anyone else has experienced this?

package.json :

"devDependencies": {
    "@types/jest": "^23.1.0",
    "@types/react": "^16.3.17",

  },

To get it to work I had to add the expo@28 version of whatwg-fetch as a dependency to get this to work ....

yarn add whatwg-fetch@1.1.1
