Hi Bastien,

after this patch the way summary is reported is different.

Before:
# 16 skipped test(s) detected. Consider enabling relevant config options to improve coverage.
# Totals: pass:53 fail:3 xfail:0 xpass:0 skip:16 error:0

After:
# Planned tests != run tests (72 != 53)
# Totals: pass:53 fail:0 xfail:0 xpass:0 skip:0 error:0

We lose the count of failed tests. Could you take a look?
