Bug Description
CoverityScan reports a potential division by zero error:
528 performed_tests++;
CID 1299399 (#1 of 2): Division or modulo by zero (DIVIDE_BY_ZERO) [select issue]
529 fwts_progress(fw, 100 * performed_
it is noteworthy that n_tests is never zero because it is related to the number of CPUs online which is always going to be > 0, but coverity does not know this and also we better ensure we check for this division by zero since the CPU online data may be not available and there is a theoretical risk of n_tests being zero.
