Re: Unit test failing but "got" and "expected" are equal

Most likely you're getting tripped up by (weirdo?) whitespace or other stuff that renders identical in the terminal.

To better diagnose that, I would dump the output on failure in a way that makes the differences spottable:

my $res = $s->gets(13);
if( !is $res, "hello, world!", "puts() and gets() ok") {
    (my $s = $res) =~ s!([^\w])!sprintf '\\x%02x', ord($1)!ge;
    diag $s;
    ($s = "hello, world!") =~ s!([^\w])!sprintf '\\x%02x', ord($1)!ge;
    diag $s;
};

Good call, thanks Corion! `# hello\x2c\x20world\x21\x0f # hello\x2c\x20world\x21` [download] At least now I have something to focus on. Update: In the meantime until I can figure out exactly what's going on, I've made the following change to the test so that my automation doesn't keep yelling at me: `like $s->gets(13), qr/^hello, world!/, "puts() and gets() ok";` [download]	[reply] [d/l] [select]

`qr/^hello, world!/` ~~You might also consider `qr/^hello, world!\s\z/` since `\x0f` is a member of the `\s` set and the quoted regex allows anything* at the end of the string.~~ No! I was thinking of `\f` (form feed) and not of `\x0f` ... never mind ... Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]

Don't feel bad, at first, I was thinking the same thing :) Because I just reloaded all of my Pi devices from scratch, I'm unsure if this is an "issue" with the config of the serial device on-board or not quite yet. All I know is that after I built my PCB hard-soldered test platform with all my ICs and sensors I'm testing, but before the OS upgrade, it worked without hiccup. No software changes to the serial code on my end (or my underlying C code), so I'm thinking it has to be how the device is configured hardware-wise.	[reply]
