[Feature]: Display all errors in AggregateError

[loozhengyuan]

🚀 Feature Proposal

To improve debugging experience, I propose to properly display errors that are of AggregateError type. This was also raised by @SimenB in #12999.

Motivation

As of Jest 29.7.0, errors of AggregateError type is displayed like this:

AggregateError:

  at Function.Object.<anonymous>.AxiosError.from (../../node_modules/axios/lib/core/AxiosError.js:89:14)
  at RedirectableRequest.handleRequestError (../../node_modules/axios/lib/adapters/http.js:606:25)
  at ClientRequest.eventHandlers.<computed> (../../node_modules/follow-redirects/index.js:14:24)

Cause:
AggregateError:

This is not very helpful because the pertinent error information exists in the errors property.

Example

No response

Pitch

N/A

I can submit a PR for this enhancement if blessed to proceed. Also, would be helpful to know if there is a desired output format for the aggregated errors. Many thanks!

My apologies, I noted in jest-message-util that there already exists logic to handle this. Closing this in favour of bug report #14704.
