I think that pretty much anyone doing automated tests so far agree that
it's better to have just all tests be written in the positive way, so
that you don't have to ever exchange the meanings of PASS and FAIL.
i needed it to test the framework itself.
i believe that this is important.
(and i am doing automated tests and do not agree that just all tests
ought to be written in a positive way)
my proposals where not about a theoretic test-framework, but based in
my practical experiences with an automated test-framework.
i that i learned quite a lot about tests....
Oh, there are lot of very practical people doing very practical testing
and never ever using fail-tests. Actually, you're the first one that ever
told me about negative tests. Anyone else would test for an error like
this:
def infinite_recursion
infinite_recursion
end
def test_infinite_recursion
begin
infinite_recursion
rescue Exception => this_error
return this_error == SystemStackError
end
return false
end
So they would check that infinite_recursion causes an error, and then
check whether it's the correct error, and then return true (PASS) if it
does, and if it's the wrong error, return false (FAIL), and likewise if
infinite_recursion ever returned. They don't ever return false to mean
true and true to mean false.
I still don't know how you got there. Good for you that you found it from
experience. I hope that it was a good experience, but if you keep it that
much secret, there's no way I can relate to that experience.
