I think you're right.  I looked ahead at page 114 and found what I
think is the first place where run() actually takes a TestResult
object, in a later chapter.  

It looks like this was an early mistake, as it appears even in the first
draft of the book which had this chapter, from March 9 last year.

Yaipa, if you submit this errata report on the testdrivendevelopment
group on Yahoo Groups it would probably be appreciated.
