Commit Message

Laura Nao Nov. 22, 2024, 3:55 p.m. UTC 
Update the functions that print the test totals at the end of a selftest
to include a warning message when skipped tests are detected. The
message advises users that skipped tests may indicate missing
configuration options and suggests enabling them to improve coverage.

This patch follows up on a previous discussion[1] and aims to highlight
skipped tests for the user's attention.
