[Feature]: support NODE_DEBUG #15261

Closed ghost closed 1 month ago

ghost commented 3 months ago

🚀 Feature Proposal

As there are many issues popping up about test execution slowness and other issues, it would be really helpful if one could get a look at how Jest itself performs and what it actually does.

Motivation

  1. It will allow users to check whether Jest itself is slow, some of their test code is slow or a dependency that they are using causing slowness or at least help pointing at something more specific to investigate.
  2. The output would provide Jest developers with hints about where to look at for troubleshooting.

Example

NODE_DEBUG=jest:* jest ...

Pitch

Only the core knows about what is executed internally and when.
