ExceptionsManager.handleException is not a function

See original GitHub issue

Describe the bug

We recently upgraded to React Native 0.63, Jest 26, and React Native Testing Library 7. When running jest with --runInBand we have noticed the following error randomly in our CI:

/node_modules/react-native/Libraries/LogBox/Data/LogBoxData.js:104
  ExceptionsManager.handleException(error, true);
                    ^
TypeError: ExceptionsManager.handleException is not a function
    at reportLogBoxError (/node_modules/react-native/Libraries/LogBox/Data/LogBoxData.js:108:21)
    at Immediate.<anonymous> (/node_modules/react-native/Libraries/LogBox/Data/LogBoxData.js:217:7)
    at processImmediate (internal/timers.js:456:21)

I noticed a similar error in the previous project: https://github.com/testing-library/native-testing-library/issues/132

Any thoughts?

Expected behavior

No errors.

This library has nothing to do with LogBox, nor ExceptionsManager. Make sure to use “react-native” Jest preset and mock the native module if necessary. Looks like ExceptionsManager is already mocked, but handleException is not there: https://github.com/facebook/react-native/blob/master/jest/setup.js#L42
