This type of testing is incredibly expensive and you'll have a startup run circles around you, assuming a startup could even exist when the YC investment needs to stretch 4x as far for the same product.
The real solution is to have individual software developers be licensed and personally liable for the damage their work does. Write horrible bugs? A licencing board will review your work. Make a calculated risk that damages someone? Company sued by the user, developer sued by the company. This correctly balances incentives between software quality and productivity, and has the added benefit of culling low quality workers.
The kind of relates to proper Engineering titles, unfortunely many countries don't have a legal system in place for those that decide to call themselves engineers without going through the exam, and related Order of the Engineer.
I don't think titles are for anything besides establishing blame. If a company hires someone in a local where the engineer can't be held responsible, the executives and major investors should be held liable. That way things will naturally sort themselves out. Need something unimportant done? Offshore. Have some critical system? Hire someone that can take responsibility.
You don't need formal licensing for this to work, passthrough liability would do plenty. The real sign of success is whether an insurance industry sprouts up to protect software engineers, just like doctors.
