OrderedCollection detect: <- exception if not found?

by sergio_101

i had a problem earlier, thinking that if i did a detect: on an ordered collection, and the item was not found, i would get back nil. it turns out that it throws an error.. to get this to work, you use: detect:ifNone: my only question is... why is this so? what is the motivation behind throwing an error rather than returning nil? i guess i would like to understand the 'smalltalkiness' about this, just in case i run into something like this in the future.. thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

The #'current' method returns the current value if it is not nil, otherwise it returns the default value. The SUnit #'setUp' method sends a new instance as the argument to #'current:', and the #'tearDown' method sets current to nil. Most of you code asks for the current value; this will be the default or the test instance, depending on whether or not the tests are running. > this sounds handy.. i am going to have to write a few of these to make sure i get it.. -- ---- peace, sergio photographer, journalist, visionary http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

SUnit is just Smalltalk code and class variables are just objects. If you modify an object it is modified. My approach to this problem is to modify the "singleton" pattern so that a class has both a "default" instance and a "current" instance. The #'current' method returns the current value if it is not nil, otherwise it returns the default value. The SUnit #'setUp' method sends a new instance as the argument to #'current:', and the #'tearDown' method sets current to nil. Most of you code asks for the current value; this will be the default or the test instance, depending on whether or not the tests are running.

SUnit - works in its own space?

by sergio_101

a quick question on SUnit.. do tests run in their own space? say i have a model like User.. User has a class variable that is an ordered collection of of users.. User userList <- should give me and ordered collection.. in my tests, if i add users to User userList.. then, in a workspace, i inspect: User userList later, i see that my tests users have in fact been added to the ordered collection.. is this expected? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101
