描述

What is the problem this feature will solve?

When running tests with both the dot reporter and coverage reports, if the coverage report fails there is no output (other than the dots) but the program exits with a failure status code.

What is the feature you are proposing to solve the problem?

Similar to this PR, it would be nice to display some sort of failure reason so its clear why the command failed.

What alternatives have you considered?

研究方向
Review the test runner's coverage output handling, particularly the dot reporter. Reference PR #52655 for a similar change. Locate the relevant code in lib/internal/test runner/ and identify where coverage failures are reported. Then implement a failure message in the dot reporter's coverage end callback.
