Hell Squeakers,
 
At home I went through the first half of the Squeak by Example book. The guided practice went without a hitch however, when I worked through the first practice of writing a simple String method at work, on a different image, I ran into this problem. Why am I receiving an 'Assertion failed' message?
 
testShout
 self assert: ('oh no' shout = 'OH NO!')
 
shout 
 ^ self asUppercase , '!'
   
TestFailure: Assertion failed
 
Regards,
