What steps will reproduce the bug?
Run a test with both --experimental-test-coverage and --test-reporter=spec arguments. When using default tap reporter, the --experimental-test-coverage shows proper tests code coverage info.
How often does it reproduce? Is there a required condition?
Always.
What is the expected behavior?
Tests code coverage info should be shown.
What do you see instead?
It's not shown.
Additional information
Since spec reporter is intended to provide an user readable output, I propose to use Istambul text reporter, that's the same being used by Jest, NYC, and by extension also c8.
