Re: Re: Re: Tripwire tests and future-proofing

From Test::More:

ok($this eq $that, $test_name);

This simply evaluates any expression ($this eq $that is just a simple example) and uses that to determine if the test succeeded or failed. A true expression passes, a false one fails. Very simple.

So it's not exactly what you describe.

Additionally a list in scalar context returns it's last value not the number of it's elements. So your explanation of what happens after the keys function is not right.

Update:

$ perl -e '%h = (1, 1, 1, 1); print scalar keys %h, "\n"'
1

$ perl -e 'print scalar (1, "a"), "\n";'
a

So it's not exactly what you describe. ~~As BUU said in his post~~ this is the `ok` from Test, not the one from Test::More.	[reply] [d/l]

Thanks. And what with the other question?	[reply]
Re^6: Tripwire tests and future-proofing by adrianh (Chancellor) on May 25, 2004 at 10:41 UTC
Two questions: How many items are in the hash in the example you gave? Does `keys` actually returns a list in a scalar context? :-)	[reply] [d/l]

keys in scalar context returns the number of elements in the resulting list. Whether this is magic in the keys function, or it's returning an "array" instead of a "list", I have no idea. `>perl -e"%x=qw/foo bar 1 2 3 4 baz bar/; print scalar keys %x" 4` [download]	[reply] [d/l]
