Playwright, the end-to-end testing framework for the web, provides a strong incentive to give sites good a11y: Playwright tests are an absolute delight to read, write and maintain on properly accessible sites, when using the accessibility locators. Somewhat less so when using a soup of CSS selector and getByText()-style locators.
One thing I am curious about is a hybrid approach where LLMs work in conjunction with vision models (and probes which can query/manipulate the DOM) to generate Playwright code which wraps browser access to the site in a local, programmable API. Then you'd have agents use that API to access the site rather than going through the vision agents for everything.
I've mentioned several times and gotten snarky remarks about how rewriting your code so it fits in your head, and in the LLM's context helps the LLM code better, to which people complain about rewriting code just for an LLM, not realizing that the suggestion is to follow better coding principles to let the LLM code better, which has the net benefit of letting humans code better! Well looks like, if you support accessibility in your web apps correctly, Playwright MCP will work correctly for you.
Was looking for this comment. I'd like to see this approach in the comparison...having the LLM build a playwright script and use it. I suspect it would beat time-to-market for the api, and be close-ish in elapsed time per transaction.
Harder to scale if it's doing a lot of them, I suppose.
There is also Testing Library, which I’ve mostly seen and used for unit tests (vitest) and component tests (Storybook), that practically forces you into setting things up in an accessible way. The methods for finding elements are along the lines of “find by ARIA role” or “get by label” - in fact, querying the DOM with selectors is afaik either not a part of the library or very difficult to do because their focus is ensuring your app is actually accessible as part of your testing strategy.
I've found that by far the most useful websites as a programmer are also the ones most resistant to AI. This would be a huge loss for anyone vision impaired
What sorts of sites are you thinking of? To me, “most useful to a programmer” evokes docs and blogs and github issues and forum posts. I suppose some forums might be AI-resistant (login wall), but the others are trivially AI accessible.
That's less a value judgment, more a necessary evil due to the plethora of bad actors out there. I doubt it will get in the way of a local model used in a reasonable manner.
Most wikis you can mirror locally if you really need to hammer them.
And lets not forget that not all disabilities are chronic. Many disabilities are situational or temporary. AI is a great assist for a hangover day for example...
as someone who doesnt do web stuff, i found some humor in having no idea what "a11y" was, having to look it up, and finding out it is supposed to be "accessibility".
my quick accessibility tip: introduce what your acronyms, initialisms, and numeronyms stand for at least once.
a11y is pretty pervasive and well understood in the context around what is being discussed. I18n as well, you get to look that one up to because that makes you one of today's lucky 10000 https://xkcd.com/1053/
I mean…I guess. But this is ridiculous - how many layers does our technology need to bash through to update two records on remote systems? I get that value is being added at some point - but just charge some micropayment for transactions. This is just too much.
