Add pa11y testing and reporting #294

bollwyvl · 2020-12-11T19:09:43Z

Hi folks!

This is an 80% solution to the up-front work of integration pa11y-ci as proposed in #292. I can split this up, if needed, but kinda felt like getting it working end-to-end (up to CI reporting) was important for demonstrating value. Note that it shouldn't fail right now, as I've whitelisted all the known error codes... that's where the 20% comes in, and each of them will likely require a design decision.

dependencies
- adds sphinx-sitemap to docs/requirements.txt
- adds pa11y-ci and pa11y-ci-reporter-html to package.json
- add .yarnrc to do a local, offline package cache
  - the pa11y stack brings in a fair number of new dependencies, this helps reduce the impact
docs/conf.py
- use sphinx-sitemap (naievly) to generate a (simple) sitemap.xml
  - this is skipped on RTD, as they generate a better one with timestamps, etc.
docs/a11y.py
- runs pa11y-ci and the report generator
- reads docs/a11y-roadmap.txt
  - the built-in stuff just hides the reports for codes... we want to see them, so we can fix them, but not fail builds while in-progress
workflows/tests.yml
- adds python 3.9, and uses it for most tasks
- adds pip/yarn caching
- adds pip check so we don't get "fun" surprises, especially with the new pip solver
- normalize the ports for the tornado server
- call docs/a11y.py
- upload report
docs/*.rst
- add metadata which ends up in the meta tags on the built HTML to maintain lighthouse score
docs/accessibility.rst
- adds some of this stuff (definitely the most WIP)
docs/contributing.rst
- update with how to run locally, etc.

I realized ignoring all of the a11y roadmap items doesn't make for good review, have commented out one to show some ❌ . Also, haven't run down the lighthouse issue, but it probably good to show that both audits run, even if one fails.

The audit step was already the long pole in CI at ~3min... we could split them up, but it would be even more duplication, etc.

bollwyvl · 2020-12-11T20:24:23Z

Ok, I'm pretty happy with my self-review of the docs, and the output that shows up in both the log and the annotations. Probably no further work planned on this, gonna bop over to #293...

bollwyvl · 2020-12-18T02:23:13Z

Just updated this to master...

choldgraf

This looks really nice and I love these docs on accessibility for the user :-) - my main concern is that the CI/CD builds now feel much more complex to me (e.g. I can read and understand the old ones with a casual glance as a non-expert in github actions, while these versions look much scarier to me (and thus will look like this for other non-expert maintainers as well, I suspect). Perhaps others can tell me if I am just being too conservative here?

But in general, I think this looks really nice, thanks for putting in this work to make sure the theme is closer to meeting the a11y goals that we should have for our communities.

I know @jorisvandenbossche may have some time to think about this theme in the next week, perhaps we can plan to discuss then?

+    - name: Cache pip
+      uses: actions/cache@v1
+      with:
+        path: ${{ steps.pip-cache.outputs.dir }}


why do we now need this much more complex install config? It's fine if it's really needed, but just looking at it seems much less-maintainable to an average person to me 🤔

sure, can drop the cache.

well if it's really useful then we should keep it, I just think we should be in the habit of justifying added complexity and maintenance burden, so I'm wondering what benefit it brings! (not out of skepticism, just because I do not know)

simplified on 8e122bb etc

Using the CI cache makes lighter use of community resources, e.g. pypi. It's not making a detectable speed difference, however in this case.

To really drive down CLI complexity, I can highly recommend doit... it's nice for multi-language projects like this.

could you add in a link to pa11y and maybe a description of what we mean by "auditing accessibility"? Many devs may have no experience with a11y or UI audits, so this is all new to them. (maybe this is just fixed by linking to the user-facing docs on a11y in this PR?)

I'll also go ahead and un-comment the demonstration rule in the roadmap, so that the audits start passing.

Alright, back to 💚... hardly seems like i could let some of the scores slide on this particular PR!

choldgraf · 2020-12-18T15:41:30Z

Great - this looks really nice @bollwyvl, thanks :-) I'll await @jorisvandenbossche's (and maybe @hoetmaaiers if he's interested) thoughts since it's a big-ish change to the CI/CD and we should get some team buy-in

isabela-pf · 2021-07-02T17:33:31Z

Is there something still blocking this PR? I'd love to see this merged since so many projects use this theme to produce documentation and this could be a great way to start bringing accessibility into more communities.

choldgraf · 2021-07-02T20:46:58Z

Mostly I think it is waiting a 👍 from others in the team (maybe in particular @jorisvandenbossche ) since it is a big ish change to the codebase

MarsBarLee · 2021-07-05T16:21:16Z

I can't comment on the changes since I don't know much about CI, but NumPy would certainly appreciate this!

bollwyvl · 2021-08-25T19:49:32Z

All back up to running/reporting... I'd be happy to start fixing some of these things (like investigating the lighthouse regressions) once we start putting these things under test...

choldgraf

This looks good to me - I don't have a ton of experience with a11y but am fine merging this in and iterating rather than having a big ol' PR dangling here.

why don't we just use sphinx_sitemap anyway? Do they clash or something? I'd be fine just using the extension rather than special-casing RTD unless it's noticeably better

Yeah, the RTD one is generally better. is aware of versions/languages, etc.

+Accessibility


Just a quick thought but doesn't need to block this PR - I wonder if the ReadTheDocs team (👋 @ericholscher @astrojuanlu) would be interested in maintaining a guide like this for the broader docs community, so it's not just in this theme.

welp, we've already seen a number of thumbs on this PR from various impactful downstreams, so there's interest. If anything, i'd rather see the baseline sphinx themes become more aware of accessible HTML5, but i haven't dipped my toe in that community, yet.

one thing we've been discussing is extracting the reporting/roadmapping capability into something standalone (e.g. local and in CI), potentially under the jupyter/acessibility banner... we've already replicated much of this over there, though it hasn't been exercised very often to keep a stack under continuous assessment. Probably out of scope for docs sites, but for complex things like web apps, there's a lot more that can be done with the keyword-based features, e.g. Click on #search-input, Type foo bar.

@bollwyvl you may be interested in @pradyunsg's effort to build a new "base sphinx template" that follows more modern best practices: https://github.com/pradyunsg/sphinx-basic-ng

We are even considering re-factoring this theme to build off of that one (potentially something that @damianavila will look into soon!)

Yeah, that would be great. Whatever it is, throwing as much possible spec validation at the lowest substantive level will yield the greatest impacts for authors and, ultimately, readers. If a subtheme comes along and hacks a span soup on top of a beautifully-organized semantic layout, then the project actually trying to publish some spec-compliant docs won't get much benefit.

As to adopting that theme: having this testing in place, at this level, starting to fix roadmap issues, and blocking merges when audits fail would make it more reasonable to do a large-scale dependency swap, and catch regressions.

yeah - I agree with all of those points.

One challenge that I foresee here is that this project already has a problem of stagnation. We have a lot of open PRs that are dangling and have gone stale (as witnessed by this PR!)...I do worry that yet another thing that raises the energy barrier to merging things will also make it less likely that anything changes.

Maybe one example is the CI/CD in this PR. It seems that something called "lighthouse" is causing the CICD to fail. I'm not really sure what that means but I think it means we are below some kind of quality standard on accessibility?

Indeed, it looks like CI hasn't run successfully for the last two months, or so.

So somewhere in the last few months, the codebase (or one or more of its dependencies that actually make DOM) regressed on performance, privacy, best practices, and/or accessibility metrics that are reflected in the lighthouse report from some "high water" mark (presumably what it was doing when I originally made the PR). We can track back to #216, when lighthouse was added, and compare against the data from when the issue arose, and start clawing value for readers back. But if nobody's looking, it can't get any better, basically the whole premise of this PR.

I see robust tests and checks as a key enabler to improving the process of accepting high-quality contributioons: there's enough important stuff reliant on this code that "move fast and break things," probably isn't the right mantra anyway.

I agree with all of this - I'm not advocating for moving fast, just trying to be realistic given the very limited developer resources this theme has on an ongoing basis.

It sounds like from an a11y perspective, and given that the tests were broken before, that the best approach would be to merge this in and then see if there are more actionable things to do to get the tests passing?

Yeah, I could unbreak some more findings (that's why that meta stuff is there, for example), but again, master isn't green right now. Once we have forensic data to start looking at, we can move forward more confidently.

choldgraf · 2021-08-25T23:20:57Z

Note for others (particularly @jorisvandenbossche I suspect). I'll plan on merging this unless there are really significant changes in 48hrs. If you object please say so and I'm happy to hold off!

choldgraf · 2021-08-27T18:50:04Z

OK - as we have (mostly) passing tests (except for one we expect to be broken on master), and since a11y is important, and since this PR has been open for 8 months, and since nobody has objected in the last two days. I'm going to merge this :-)

thanks @bollwyvl for slogging through this one!

isabela-pf · 2021-08-27T18:54:50Z

Hooray! Thanks @bollwyvl for sticking with this and @choldgraf for getting it reviewed and merged! This is a big step to helping a lot of projects identify and fix inaccessibility in their documentation. 💕
