Hi all,
i wrote a test with 

my $score = result_of_a_function();

cmp_ok($score, '==', 0, 'scores 0 in blablabla context');

[download]
But am quite annoyed, as the test passes when the (unimplemented) subroutine returns 'undef'.
It is annoying, as when i want to display my score : 
print $score;

[download]
it doesn't display anything. If it displayed 0, i would probably be quite happy.

undef==0, it's a feature of the language, i have to accept it and adapt. Which is very simple: when i want to test that a value is 0, i can just use 

is($score, 0, 'scores 0 in blablabla context');

There are good reasons for this choice, it is sometimes very handy to use strings or numbers in each other's place.
But i still feel slightly annoyed right now (^c^)

EDIT : the problem was wider than i thought : 

1>undef

[download]
also returns true. Which means that any 
cmp_ok($got, '<', $expected)

[download]
statement runs into the same risk / problem.

In reply to 0==undef, that's annoying. Is it? by mascip
