COUNT And SUM In Same Query?

This query gives me part of what I want:

SELECT
TS_EXEC_STATUS as 'Status',
COUNT(*) as 'Total',
FROM TEST
WHERE TS_EXEC_STATUS <> ''
GROUP BY TS_EXEC_STATUS
ORDER BY TS_EXEC_STATUS

This query returns this:

Status Total
Failed 3
No Run 132
Not Completed 6
Passed 106

But I would like two more lines so the results are like this:

Status Total
Failed 3
No Run 132
Not Completed 6
Passed 106
Total 247
Percent Passed 42.9

I don't know how to get the last two lines with the Total of 247 and the Percent Passed of 42.9 (106/247).
