At that point they were public and had a $100B+ market cap.  I&amp;#x27;m sure there are other public companies out there who don&amp;#x27;t do automated testing &lt;i&gt;at all&lt;/i&gt;.&lt;p&gt;The technical infrastructure and code quality of a company are secondary factors in its success.  The biggest influence they have is in the ability to attract and retain brilliant engineers, because most brilliant engineers don&amp;#x27;t want to work in a place where they&amp;#x27;re just treading water with bugfixes (which is the situation you eventually get into without automated testing).  But the mechanism is that brilliant engineers write features that your competitors can&amp;#x27;t match, not that testing itself will make you successful.</text></comment>
