Okay, as the results showed, an object "x" of class MyTest does not
equal the
string results of the method .to_str called on the x object.

assert_equal ("hello", x.to_str)

is what you want :)

No surprise here, either. You have added a method, to_str to the String
class,
but when you instantiated the Object you did not make any assignment to
the string itself.

If you say, for example:

b= String.new
puts b

you would get the same result, because this is essentially the same
thing.
In your a class, a.to_str should work, I believe, but in my mind, all
bets are off because you are changing the behavior of the built-in
String class, which is generally "a bad thing" unless you are very
careful.

Cheers,

Howard

Wrong on both counts, because they did. At least once. You must

More private sector jobs now.

Though the rethugs plan to cut all jobs a LOT.
