Re: [Wikimedia-search] [reading-wmf] [QA] top articles across languages for testing?

For Parsoid, we run tests [1] against a set of 160K articles that we randomly picked a couple years back .. about 10K articles from 16 wikis. For Parsoid's purposes, we run roundtrip tests (wikitext -> html -> wikitext) and compare diffs, as well as run trivial edit tests (wikitext -> html -> add comment at end of page -> wikitext) and check how clean our roundtripping is. This testing has been extremely good at telling us when something is broken vs. when something is good to be deployed. Checking these results is part of our deployment process. We also collect performance statistics in each testing run, however our testing database / database schema is not sufficiently tuned to let us actually track performance regressions well .. so, that data has just sat in the db without being used for anything. But, we've also been recently talking about: * refresh this to pick a more proportional set of articles from different wikis (more from enwiki, less from others, etc.), but not yet done this. * throw in a different (non-random selection) set of pages that are particularly important (featured articles, etc.). so, we would be interested in any set of articles that is considered important enough to be regularly tested against. This map-reduce style testing code is somewhat general enough that it could be repurposed for other kinds of testing. For example, we have also repurposed this same rt-testing code for running visual diffs (compare phantomjs renderings of php parser output and parsoid output on the same title) on a set of about 800 enwiki articles (random selection) [2]. This kind of testing is very essential for our deployments and not sure if it is appropriate for other teams .. but sharing just in case. Subbu.

The main page is http://parsoid-tests.wikimedia.org but this page can sometimes timeout whenever the db is clogged and old test results need clearing out.

One group is a set of articles that used to have some sort of performance/display issues - Barack Obama, Cat, India, Richard Nixon, Europe, English language Another group of articles - where images or Image Gallery is tested(gif, svg, image map, charts, timeline, large amount of imgs in the Image Gallery) - *Claude Monet *- extensive Image Gallery(different img sizes) - *List of go games* - many svg images - Lilac chaser, Caridoid escape reaction - animated(gif) images - *The Club(dining club), Image map* - for image map img - *Tel Aviv(Hebrew*) for timeline img template - several specific articles with problems in their lead img And, yes, it'd be really great if we can 1) define more precisely what articles properties we are interested to test(visiting statistics, size, structures, special layouts, imgs etc.) and 2) create a process(system) to find such articles Also, there is still an open task - https://phabricator.wikimedia.org/T97151 - Testing Page issues and disambiguation templates(T90250). Going through the list of http://en.wikipedia.org/wiki/Category:Wikipedia_articles_with_content_issues http://en.wikipedia.org/wiki/Wikipedia:Template_messages/General#Disambigua… should help to catch some issues. thanks Elena On Tue, May 19, 2015 at 9:23 PM, Brian Gerstle <bgerstle(a)wikimedia.org> wrote: _______________________________________________ QA mailing listQA@lists.wikimedia.orghttps://lists.wikimedia.org/mailman/listinfo/qa _______________________________________________ reading-wmf mailing list reading-wmf(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/reading-wmf
