SYNOPSIS

    use Test::HexDifferences;

    eq_or_dump_diff(
        $got,
        $expected,
    );

    eq_or_dump_diff(
        $got,
        $expected,
        $test_name,
    );

    eq_or_dump_diff(
        $got,
        $expected,
        {
            address => $start_address,
            format  => "%a : %4C : %d\n",
        }
        $test_name,
    );

If $got or $expected is "undef" or a reference, the hexadecimal formatter is off. Then "eq_or_dump_diff" is a text compare.

    dumped_eq_dump_or_diff(
        $got_value,
        $expected_dump,
    );

    dumped_eq_dump_or_diff(
        $got_value,
        $expected_dump,
        $test_name,
    );

    dumped_eq_dump_or_diff(
        $got_value,
        $expected_dump,
        {
            address => $start_address,
            format  => "%a : %4C : %d\n",
        }
        $test_name,
    );

See Test::HexDifferences::HexDump for the format description.

EXAMPLE

DESCRIPTION

• The ascii format is not good for e.g. a length byte 0x41 displayed as A.
• Multibyte values are better shown as 1 value.
• Structured binary e.g. 2 byte length followed by bytes better are shown as it is.
• Compare 2 binary or 1 binary and a dump.
