So you are suggesting an extension of SUnit. Great. You just forgot to
attach your code ;-)
BTW: I think the current imnplementations of SUnit already carry a large
amount of pollution. Just because JUnit and friends introduced special
methods for testing equality and such, we also have this noise in SUnit.
This is not to say your suggestion would be useless. Just make a
proposal and let's discuss.

Forgive me father, for I have sinned… but when I try to right good tests, that
fail in a way I can understand them it seems that SUnit doesn’t want to help me…
Maybe I am missing something, but in 2019 it should be easy to write tests -
particularly when we want people to contribute to adding more?
So when I want to right a test to assure that I’ve thrown an exception with the
right message, why is it so hard (in the core image)? Am I missing something
obvious?
My example model is supposed to throw a DomainException with a message
indicating that the strings :are of different lengths” - I search Sunit and hit:
#should: raise: whoseDescriptionDoesNotInclude: description:
Awesome, so it fails - but does it make it easy to know what damn string I
got….. nooooo that would be too easy? Its almost impossible to easily see what
happened the way it works.
Instead I have to write:
self
should: [ hammingCalculator distanceStrand1: 'AATG' strand2:
'AAA' ]
raise: DomainError
withExceptionDo: [ :ex |
self assert: ex messageText equals: 'left and right
strands must be of equal length' ].
And god forbid if I want to just ensure that the beginning of my error message
is correct?
Why do we make this so hard? I know we don’t want to pollute the image, but
testing is important, it should be easy for obvious cases and it should be more
built in and less obscure. Is there something built in that makes this easier?
Do I really have to load in more libraries for the easy cases?
