Unreliable unit tests #1908
Description
Some unit test randomly appear to fail in certain conditions (for example when using Node.js 20 or later).
Example 1 (unit tests related to code push):
340 passing (621ms)
1 pending
3 failing
1) getCodePushInitConfig
should return the access key from code push config if keys are present in both config files:
AssertionError: expected undefined to equal '1e2509c78c4f94c25e69131a0a5e5be3b7d2927b'
at Context.<anonymous> (test/getCodePushInitConfig-test.ts:40:53)
at processImmediate (node:internal/timers:478:21)
2) getCodePushInitConfig
should return the access key from code push config if key is not present in .ernrc:
AssertionError: expected undefined to equal '1e2509c78c4f94c25e69131a0a5e5be3b7d2927b'
at Context.<anonymous> (test/getCodePushInitConfig-test.ts:55:53)
at processImmediate (node:internal/timers:478:21)
3) getCodePushSdk
should not throw if an access key exists:
AssertionError: expected [Function: getCodePushSdk] to not throw an error but 'Error: Unable to get the CodePush config to use' was thrown
at Context.<anonymous> (test/getCodePushSdk-test.ts:43:40)
at processImmediate (node:internal/timers:478:21)
Example 2 (two different unit tests related to CauldronHelper):
460 passing (6s)
2 failing
1) CauldronHelper.js
getYarnLock
should return the yarn lock if found for key:

2) CauldronHelper.js
updateYarnLock
should update the yarn lock:
Error: ENOENT: no such file or directory, open '/var/folders/xb/4lt2zppd3cnc6qhcc09wxb8r0000gn/T/tmp-32217-Lp4GZ8AHiQVY/yarnlocks/f2886fd3-3824-4e2b-ac07-2f116b691674'
