	The stats printed at the end have no account of whether the test passed
	or failed. As seen in the totals message at the end, all the values for
	various test results (pass, fail,xfail, xpass,skip and error) is 0.
	With this patch we'll get the totals at the end of test like:
	# Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0
