I was going to mail this to Chad directly, but I think it’s worth airing
publicly.
As a newcomer to Test2, it was never clear to me until just now when to use
is() or like() for deep structures. Given this code:
my $errors = do_something();
is( @{$errors}, 0. ‘No errors back from do_something()’ ); # old way
And the new way to check would be:
is( $errors, [], ‘No errors back from do_something()’ );
It would be very easy to use this instead:
like( $errors, [], ‘No errors back from do_something()’ );
And it looks like like() works just fine, but really it will pass even if
$errors has something in it.
is( [], [] ); # Passes
like( [‘foo’], [] ); # passes but you wouldn’t expect it to.
The docs say "This is the strict checker” and “This is the relaxed checker” for
each of them, respectively, but I think it would be worth having something in
the docs that explains the differences between the two.
Anyone else have troubles with these two functions? Or other gotchas where new
features aren’t what people switching from Test::More might expect?
