[Bug]: toEqual() fails jest-worker with "Do not know how to serialize a BigInt" when reporting a failed test

[jstritch]

Version

27.4.7

Steps to reproduce

expect(BigInt(0)).not.toEqual(BigInt(0));

Expected behavior

1. The expectation should produce the typical expected/received message.

2. When an individual test fails catastrophically, the failing test should be identified to the user and the entire suite should continue with any remaining tests.

Actual behavior

Summary of all failing tests
FAIL  tests/parsers.test.ts
● Test suite failed to run

        TypeError: Do not know how to serialize a BigInt
    
            at stringify (<anonymous>)
    
          at messageParent (node_modules/jest-worker/build/workers/messageParent.js:34:19)

Ran all test suites.

Additional context

Possibly related issues:

• 11617 - jest-worker fails with "Do not know how to serialize a BigInt" in messageParent.ts instead of showing the actual assertion error message when there are 2 or more test suite files executing in parallel

Please respond to my second expectation. It would have been easier for me to track down if the test name was included with the other information. Is it possible to add a catch handler inside the loop running the individual tests?

[SimenB]

This actually fails outside of the context of a single test (it fails when jest tries to pass the test result from a separate thread/process back to the main process), so we don't know which specific test failure caused this error.

I hope to address this issue in Jest 28 (see #11467 (comment) for latest info)

[jstritch]

If no object has both the test name and result to format at the same time, is it possible to pass the test name along to include in the error message?
