Test runner coverage thresholds must show up in red

Description

Another small visual tweak.

The spec reporter must show errors on coverage thresholds in red.¹
As it is right now, visually - it looks like the tests pass.

I can imagine it can create a lot of back/forth in code reviews.

You'll only realise there's a problem when the CI cycle fails because it correctly exits 1. That sucks because debugging in CI is as pleasant as watching paint dry.

I'm talking about the last line of this:

ℹ duration_ms 60.134125
ℹ start of coverage report
ℹ test/exceptions.test.js | 100.00 |   100.00 |  100.00 | 
ℹ ------------------------------------------------------------------------
ℹ all files               | 100.00 |   100.00 |   95.08 |
ℹ ------------------------------------------------------------------------
ℹ end of coverage report
ℹ Error: 95.08% function coverage does not meet threshold of 100%. <-- this must be more pronounced. It's in blue right now.

here's how it really looks:

Minimal Reproduction

node --test foo.test.js --experimental-test-coverage --test-coverage-lines=100

Output

No response

1. I'm aware of the accesibility concerns about using color, not sure how it's dealt or if at all. ↩
