I recently hit an odd accident that turned into a cautionary tale about test data.<p>Someone was testing one part of a new ecommerce system, at precisely the same time someone else was testing another part.  No-one noticed until DHL returned a package that was addressed to the Death Star.<p>They still charged us shipping, but atleast we didn&#x27;t have to swallow product cost too.  But it did make me look at &quot;random test data&quot; quite differently.
