Current status

Matt_King: We have a pull request in review that changes the reference example

Matt_King: It doesn't affect all tests, though--it only affects the tests that Joe reported where the heading is being hidden

Matt_King: For now, it would be best to skip the tests in the radio group test plan where the heading is hidden by the setup script

IsaDC: The name of the group is "pizza crust"

IsaDC: I would advise against running any of the tests

Matt_King: I'm fine with that

Matt_King: In terms of the bot, though, once we have the new version of the test plan in the queue

Matt_King: Was the question about the bot regarding the version of the bot?

dean: I was just wondering if someone would run this test plan with the bot before I do

Matt_King: I believe the answer is "yes"

Matt_King: Though there was recently a macOS update... What version of macOS is the bot currently running?

howard-e: It should only be able to run the latest version of 14

Matt_King: But now, we have all the testers running macOS 15

IsaDC: Yes, and it is important to have the bot running that version because there have been regressions with VoiceOver. The bot wouldn't catch those if it used the older version of macOS

Matt_King: Is something preventing us from upgrading the bot?

howard-e: There have been issues that were previously reported to GitHub; I'm trying to pull up the details on that, now

Matt_King: Okay, well, for disclosure. mmoss, you are recording those without the use of the bot, right?

mmoss: That's correct

Matt_King: It looks like you're just getting started. I guess we don't have any problems there, then, right?

mmoss: Nope! The recorder was doing something strange, but I think I've worked that out

howard-e: We don't support macOS 15 yet because GitHub doesn't fully support it, yet

Matt_King: So we're dependent on GitHub, then

howard-e: That's right

Matt_King: I guess there's no way for us to work around that dependency

Matt_King: I wonder what's holding things up. That could end up being a real inhibitor to the project. What if it takes them a year to support it?

Matt_King: Should we raise a support ticket with GitHub?

jugglinmike: I believe the maintainers of Guidepup have reported it, already

<howard-e> actions/runner-images#11257

howard-e: And it looks like they've replied within the last few weeks. We at Bocoup queried just a couple days ago

Matt_King: I wonder if that kind of dependency is a risk to the project that we should be thinking about other ways to work around

Matt_King: Perhaps Assistive Labs has more control over their systems...

Matt_King: I suppose the alternative would be building a new approach to how we run automation

IsaDC: We did some work with Assistive Labs, so I may be able to ask them. What do we need, exactly?

Matt_King: I think jugglinmike or howard-e would be the best to write a request like that

Matt_King: I'm not sure we want to request it just yet. But GitHub's lack of support does seem concerning, given how long that version has been publicly available

Matt_King: So for the link examples, I see a new 2025-01-23 version here

Matt_King: We need to assign people, right?

IsaDC: no--Luke from PAC is re-running them, and I've already run some in NVDA to catch up with VoiceOver. It should be out of the queue by the end of Friday

Matt_King: Awesome! That's really good

Matt_King: So, at this point, dean is on hold and mmoss is plugging away

Matt_King: I think we'll get dean back on pretty soon. I think what I'm going to do, IsaDC, is prioritize the review of the radio stuff (because I think that's simpler), then I'll come back to slider after we solve the issues in the next discussion topic

New slider assertions

Matt_King: The best thing for people to do, to make this discussion really concrete, is to look at the examples while we're discussing them

Matt_King: In the agenda, I put links to two different APG examples. I also put a link to a draft test plan

Matt_King: Now, for the question

Matt_King: there are four different properties associated with slider. Three take numbers, and the fourth is aria-value-text (a textual value that is used in the event that the author believes that a number on its own is not understandable)

Matt_King: A good example for that is if you have, say, days of the week that are represented by numbers. The author can use aria-value-text to associate those numbers with names of week days

Matt_King: The author is also required to set value-min and value-max. In that example, those would be 1 and 7, respectively

Matt_King: If the screen reader is going to read, say, "Monday," and you were to hear "min one max seven"

Matt_King: It seems relatively clear most of the time that those minimum and maximum values are not relevant to screen readers

Matt_King: But we have examples in APG that make that a little less clear

Matt_King: In the first, we use "value text" so that it can say "degrees Celsius" when you're hearing the value

Matt_King: The slider goes from 10 to 38

Matt_King: For whatever reason, ARIA requires the author to set those. At least right now, JAWS is dutifully reporting those in certain circumstances

Matt_King: The way I hear with with JAWS as the example exists in the APG, "temperature up down slider 25.05 degrees Celsius min 10 max 38"

Matt_King: That makes sense. In this case, there's no harm in hearing the minimum and maximum

Matt_King: However, if you look at the "Seek slider" example in APG

Matt_King: In this case, the slider goes from 0 to 300 seconds, but humans don't think very well in terms of time using seconds.

Matt_King: When you go to this slider, JAWS will say "1 minute and 30 seconds of 5 minutes" that is the value text when the value is 90

Matt_King: JAWS goes on to say "min 0 max 300"

Matt_King: So the question is: is the maximum 300 minutes?

Matt_King: So there's an argument that there's harm for JAWS to be doing that

Matt_King: This example makes it more clear what the problems with announcing the numeric min and max

Matt_King: So that's the problem, in a nutshell

Matt_King: Do you folks understand the properties, how authors use them, and what screen readers are doing?

mmoss: It all makes sense to me

mmoss: And I agree that it's very confusing for the horizontal slider

dean: I'm sorry, I missed that.

dean: I'm not assigned to the slider yet, right?

Matt_King: No, you're not. We're still trying to figure out what we should be asserting for the slider

Matt_King: There are at least two possible ways of approaching this problem

Matt_King: But before that, I wanted to know if what I was saying makes sense to you (about the numeric properties and how they interact with aria-value-text)

dean: Yes

Matt_King: Good

Matt_King: So, for the ways we could approach this

Matt_King: We could say, "you must not say the min and the max if value-text is specified"

Matt_King: Right now, they don't say "value-now" if "value-text" is specified

Matt_King: We could write "negative assertions" (i.e. "MUST NOT" or "SHOULD NOT")

Matt_King: Another option could be to not have any assertion at all and label it "unexpected verbosity" and call it a negative side-effect

dean: I can't see this because it's not in the test queue

Matt_King: I put a link in the agenda

dean: I didn't bother to look at the agenda. I apologize

Matt_King: These are two examples in the APG where the APG example author intentionally are trying to show how to go beyond--how to use "value text" in a way that is helpful to users

Matt_King: By the way, I have seen media seek sliders where the value of the slider is in milliseconds

Matt_King: This media seek slider was actually inspired by that nonsense

dean: I'd go so far as to say that--and I haven't done a lot of work with sliders--we need to give people the ability to turn off the noise. As in, I don't need to know how much time is left because I don't care

dean: I don't know if we have that mechanism available

Matt_King: If you had the focus on the slider while the media is playing, you might get that kind of behavior. As a screen reader user, though, you wouldn't keep the focus

dean: Oh, that makes sense

Matt_King: When I looked at the plan, I started to get a little uncomfortable with these "negative assertions"

Matt_King: I am not happy with what ARIA is doing here. It feels to me that we should have an "ARIA min text" and an "ARIA max text"

Matt_King: ...or we should say, "if aria-text" is specified, you don't have to specified min and max. Maybe even make it an authoring error to do so

Matt_King: Right now, it's on the screen readers to ignore the numeric values if text is specified

Matt_King: I'm not sure changing ARIA is a good path forward for this project right now. I'm not even sure it's feasible (there could be important and valid reason for the current design)

Matt_King: I'm mostly thinking about how we deal with the status quo if we don't change ARIA

Matt_King: A negative assertion makes it really clear to screen reader developers what needs to be ignored in cases like this. There's a part of me that leans against negative assertions and to just code this behavior as excess verbosity

Matt_King: If we just rely on testers to identify excessive verbosity, then that's not a very robust test

IsaDC: I think it would be more appropriate to use it in the media slider to demonstrate how disruptive it is to hear those min and max values

mmoss: Thinking about verbosity in general and whether or not some people might want that verbosity... We probably want the default behavior to change but to keep optional behavior

mmoss: I hesitate to circumvent testing first

Matt_King: So would that mean leaning in the direction of a "SHOULD NOT" kind of statement?

mmoss: I've always wondered about the specification itself as it relates to min and max

Matt_King: Yes. It is actually written in the ARIA spec that if you have value-text, it is a replacement for value-now

mmoss: That's my understanding, as well

mmoss: IsaDC mentioned leaning in to the media slider as the test case to demonstrate. I think that might be really helpful

IsaDC: Yes, that would should "one minute of five" with a minimum of 0 which is fine, but the maximum would be 300

Matt_King: We could have made this more obvious if we designed it to use milliseconds...

mmoss: Is it verbosity?

Matt_King: I'm not sure I would call it excess verbosity in the strict sense

Matt_King: I mean, technically, it is. It's extraneous

Matt_King: There is a rating slider which uses the same technique in the APG

Matt_King: It uses a slightly different approach

IsaDC: It uses stars. I think media seek slider is a much better illustration of the problem

IsaDC: I'm leaning toward using a negative assertion because it's more clear for testers

jugglinmike: Historically, when we've observed excessive output, we've simply failed the test. We're discussing a lot about this, though. Is that because we recognize the cause of the behavior and we feel that other screen readers are likely to make the same mistake?

Matt_King: This is unique because it's a case where rendering attribute values is a problem

Matt_King: This might be another argument in favor of negative assertions

Matt_King: Telling authors about what to expect based on their markup makes it more clear in my head about why it is really clear to have negative assertions

Matt_King: So I'm glad you asked that, jugglinmike

Matt_King: So I think the plan is for IsaDC to do what she's done with this plan but to use SHOULD

IsaDC: I expect to be able to bring a draft to our next meeting. Then we'll be able to review the effect of a negative assertion in a more practical way
