@vivek378521
please see the discussion on the issue: #45911,
there are some top-level diagnostics that need to be omitted, and some that don't need. this fix will introduce another issue where each file will include the summary that should only be included in the entire run:

# tests 1
# pass 1
# fail 0
# cancelled 0
# skipped 0

additionally - we generally remove unused code instead of commenting it out
