I forked and cloned the repo this morning (at c88fb49d37fd01024e0a254a37b7810d107bdd1d), ran `yarn` and `yarn test`, and several tests failed.

React version: main (c88fb49d37fd01024e0a254a37b7810d107bdd1d)

## Steps To Reproduce

1. Clone repo
2. `yarn` and `yarn test`

I was on the latest NodeJS version (16.10.0). Note that tests pass for me when switching to the 14.x LTS release of Node.

## The current behavior

13 tests fail across 5 suites. Output at https://gist.github.com/josephsavona/91a3d48add8a1c47c71178522583281b

## The expected behavior

All tests pass
'use strict';
const chalk = require('chalk');
const util = require('util');
const shouldIgnoreConsoleError = require('./shouldIgnoreConsoleError');
const {getTestFlags} = require('./TestFlags');
if (process.env.REACT_CLASS_EQUIVALENCE_TEST) {
  
  
  require('./spec-equivalence-reporter/setupTests.js');
} else {
  const env = jasmine.getEnv();
  const errorMap = require('../error-codes/codes.json');
  
  
  
  const isSpy = spy => spy.calls && typeof spy.calls.count === 'function';
  const spyOn = global.spyOn;
  const noop = function() {};
