dear John, If I would not advocate testing I would be a bad entrepreneur/ If I would recommend clearly unnecessary testing I would loose customers.
The same is true for dentists curing your dents. Did YOU actually check every hole in your teeth really existed ? Or did you never go to the dentist because no authority demands it. ;<)) It is the difference between good and bad test houses to help selecting test suites for unknowing customers (!??!) that other otherwise choose for short time gains and long time losses. And, as you should know, testing costs are important for very small companies only. Costs for EMC serial production etc. are neglect able if designed in, from the start. The gain from compliant equipment in terms of quality, product life time and need for service can easily be much higher then all testing suites I can imagine. And there is much more to test than only EMC !
