The mistake is simple. You have to write as follows (just replace cell for self in two lines before should and shouldnt):

testCellOnState
� � � | cell |
� � � cell := BlankCell new.
� � � self should: [ cell isOff ].
� � � self shouldnt: �[ cell isOn ].

You are abolute right.
Wierd that earlier test succceed where this error also is made.
