Hi guys. I always code my tests something like this:
testBlah
| universalAnswer |
universalAnswer := 30.
universalAnswer := universalAnswer + 11.
self assert: universalAnswer equals: 42.
In this case, 42 is the "expected" and "universalAnswer" is the "actual"
value.
I feel weird writing like this:
self assert: 42 equals: universalAnswer.
I don't know why...but I do..the same as when doing should: [] raise:
Error.
In that case you put the "actual" first and the "expected" at the end...
ok....the "problem" is that assert:equals: is in fact: asserts: expected
equals: actual instead of
asserts: actual equals: expected
So, with my test I would receive a description in the debugger that says
"'Expected 41 but was 42.'"
which is completely the opposite. Of course, if I write my tests in the way
I don't like, that is:
self assert: 42 equals: universalAnswer.
then i got the correct message "'Expected 42 but was 41.'"
I don't pretend pharo change this because I guess it is standard, and blah
blah blah. But senders of #assert:equals: should both, some written as mine
(so the message is incorrect for them) and some correct.
In addition, I think it is a problem of the selector name. If we could make
it clearer, the won't be necessary to confuse "actual" with "expected".
Cheers
