You properly doubled the single quote inside the first string. However, you
used two double quotes inside the second string; replace them with two
single quotes.
You also have an exclamation sign in the second string which is not in the
first one. Remove it and the test will pass. Note that the exclamation mark
in the following method is inside a comment:
After that I added this as described in the book.

This is fine. The ending period is not needed, though. Periods work as
statement separators in Smalltalk, not terminators as semicolons in C, for
example.
If you really want to have an exclamation mark added to the string, you
should implement shout as this:
shout
^ self asUppercase , '!'
