For example #(1 1 2) has same elements as #(1 2) which may make sense for sets, but not for bags.
The main reason I was using it is that in tests the expected collection may be created by hand, which means it is very often an array #(...), { ... }, while models very often return OrderedCollections (at least in my case).
I introduced #assertCollection:hasSameElements: for this reason. The problem with using sets is that I do not expect that #(1 1 2) has same elements as #(1 2)
So my question is --- how to compare collections irrespective of type, and possibly of order?
A) always convert the actual collection toanArray
B) change difference: behavior for non-sets (ton of work with catastrophic consequences)
C) extend TAssertable with new methods like
#assertElementsOf: actualCollection equals: expectedCollection #assertUnorderedElementsOf: actualCollection equals: expectedCollection
This solution has my preference
C.a) directly in Pharo/SUnit
yes, for me, it is a very basic assertion that should be available as default.
C.b) in independend SUnit-Extensions repository/project C.c) just in my project
D) stop discussing non-problems
Thanks, Peter
