ipp-tests.test: Test I-10 fails to detect missing required keywords for "print-color-mode" and perhaps other attributes

[wifiprintguy]

In IPP Everywhere 1.1, "print-color-mode-supported" is a required Printer Description attribute, and 5100.14-2020 adopted the requirements from 5100.13-2012, which requires the Printer to support the 'auto' and 'monochrome' keywords (Table 6). This requirement didn't change in 5100.13-2023.

But the test on line 467 of ipp-tests.test fails to test this correctly:

ippeveselfcert/tests/ipp-tests.test

Line 467 in 4375a48

EXPECT print-color-mode-supported OF-TYPE keyword IN-GROUP printer-attributes-tag WITH-ALL-VALUES "/^(auto|auto-monochrome|bi-level|color|highlight|monochrome|process-bi-level|process-monochrome)$/"

It checks that it lists one value, but doesn't disambiguate between required and optional keywords. The 'monochrome' and 'auto' keywords are required, and should be tested on separate lines, or perhaps the regex needs to be rewritten?

[michaelrsweet]

The current test requires that all of the xxx-supported values be one of the registered values for print-color-mode (WITH-ALL-VALUES tests all values, and the regular expression lists all of the registered values as options).

You are correct that the current test doesn't require 'auto' and 'monochrome', it just requires that the printer supports the attribute and that all values are registered values.
