This is simply NOT TRUE and shows a complete lack of understanding of software 
testing.
Even if a company (or OS developer) implements automatic tests that cover each 
and every existing functionality this does NOT automatically ensure, that the 
existing functionalty works together well with new features. Nor does it 
ensure that existing code does work as intended under NEW circumstances.

Testing (and I mean ANY form of testing, be it automatic or manual) can NEVER 
ensure the abscence of bugs!


Additionally: Companies will never even atempt to find any bug. They will 
always only try to find as many bugs necessary to ensure that the cost of 
maintenance, bug-fixing, compensations and possibly loss of prestige does not 
exceed the cost of testing. Anything else would be financial loss.
