jest: Test suite failed to run, TypeError: Cannot read property 'bind' of undefined

Question

we were using jest from unit testing in react-native. It was working well. We just deleted npm and installed it again and then when we tried to run unit test(npm test) we are getting following error and we are not able to run test cases.

What might have went wrong.

Answer 1

React 17+

  "devDependencies": {
    "@testing-library/dom": "^8.11.1",
    "@testing-library/jest-dom": "^5.16.1",
    "@testing-library/react": "^11.2.7",
    "@testing-library/user-event": "^12.8.3",
    "@types/jest": "^26.0.24",
    "@types/react": "^17.0.27",
    "@types/react-table": "^7.7.7",
    "jest": "26.0.1",
    "ts-jest": "26.0.0",
    "typescript": "^4.5.4"
  }

Error was on jest 27+ version but after setting to 26 it works well.

Answer 2

Try to re-install both jest and jest babel last versions

npm install --save-dev jest

npm install --save-dev babel-jest regenerator-runtime

And re-run the test, it works for me
