RE: WCAG 2.2 acceptance criteria

Part of the concerns the COGA group discussed was that manual tests are often required, and the variety of time required to test different pages can vary greatly, depending on the content of that page.

One example we discussed was the current testing required to ensure that the appropriate alt text is assigned for each image used on a page. 1-2 images on a page, not a big deal to test. But, on a catalogue page, it could be significant.
The question came down to the concept that there may be manual testing that (at this time) may be the only way to truly ensure a barrier is not met by individuals with cognitive disabilities.

I, too, work in an environment where a lot of testing occurs every day. And, we have to hold contractors, vendors, and employees to standards that can be measured. We need to be able to provide detailed and consistent feedback when a failure of a success criteria has been noted. The time taken to complete testing is definitely important. But, consideration of barriers is the whole goal, right?

From a matter of equality standpoint, why would the testing to address the needs for one group be ok if it takes a lot of time, because they got in on the creation of success criteria at the beginning of the process; but for another group who’s needs were addressed more thoroughly later in the development of success criteria, manual testing that may sometimes require some time cannot be considered?

I would like to propose that the language about the time it takes to complete a test have an exception process, or propose a rewording of the time component, so that the barriers experienced by this group of individuals with disabilities receives fair consideration in this process.

Hi All,

To perhaps also put a finer distinction on it... W3C Process mandates two independent implementations of whatever new technology is being proposed - a testing activity we actually did last spring during CSUN for the 2.1 Success Criteria (where, for SC 1.3.6 @ AAA we actually used the implementations that Lisa had pointed us to). Those implementations may or may not also serve as a 'testing tool', but as the Silver discussion continues, a repeatable testing methodology will need to surface for each new requirement, whether that is via a tool (mechanical tests - see: ACT TF), or via a 'cognitive walk-though' or similar methodology (a process still to be fully defined in Silver).

At the end of the day, while it is true that our primary audience is and will always be users with disabilities (of all stripes and forms), a second important consideration is compliance requirements mandated by legislation. To clear that hurdle, we will need to ensure that both implementers and consumers have a baseline measurable & impartial (non-subjective) "test", so that entities can then claim conformance based upon the outcome of said test.

Which is fine, perhaps we can clarify that it means available at the time of publication?

New tools, especially if they “take a day” from a programmer would need to be available at the time of publication, for the reasons I outlined in the last email.

Can you point to a previous example? I.e. where a tool that didn’t exist was required to meet an SC wasn’t available until after CR?
The closest I can think of is ARIA in WCAG 2.0, but it wasn’t actually required to meet the SCs.

It is very difficult to deal something in CR which then has to be pulled because no one has created a tool, the whole timeline goes back a step. The way the W3C prefers to work is to have working prototypes/code created prior to specs. This has been a hard-learned approach [1].

I suggest that if an SC needs a tool, we work up the SC template and go through the initial process. That could be accepted on the condition that a tool will be available. If it does not become available then the SC will be removed before CR.

It would also help to put those SC(s) first so people have more time to work on the tools, I’ll make a note of that.
