Re: TestFailure: Assertion failed in first practice from Squeak by Example

Hello Jerome,

 

I checked the white space and it was the same. I went and created numerous other String methods basically invoking existing methods and every test run seems to yield a signal failure causing the assertion to fail. I moved from the Cassou Dev Image to the OLPC Etoys Dev Image and made several of my own String methods and respective tests which all ran successfully. I don't know why my coding didn't work in both cases. Thanks for the time. Have a good day.

 

Regards,

Hi Eric,

Check your white space.

There is a difference between 'oh no' and 'oh no '.
While its hard for me to tell if this is your problem
it is a common difficulty. And it will be easy for you
to eliminate it as a possibility.

Hth.

Yours incuriosity and service, --Jeorme Peace

Yes, the shout method is defined in the String object.
