Because imports are processed asynchronously, an error within one import causes the test runtime to abort and be torn down, which causes the other imports to log numerous redundant errors. Because these errors have no stack traces, they're even more verbose than necessary, with lots of blank lines.
Sample output for one of my projects:

To address this, I added logic to suppress redundant errors and to only include stack trace newlines if a stack trace is present.

Jest should perhaps suppress all reference in-teardown errors if it knows an error was thrown. I can look into making that change as well or instead if there's interest. |
