What specifically should I be testing? Can you expand the test steps?

[mediawiki/core@wmf/1.46.0-wmf.24] Move language variant parser option setting from Article to WikiPage

https://gerrit.wikimedia.org/r/1272875

Here's my recommended test set up:

First, set up your test wiki with a language that uses language variants. I recommend:

$wgLanguageCode = 'en';
$wgUsePigLatinVariant = true;

but you could also set your local wiki language to sr or zh, etc.

Then perform the following tests. I recommend using all three (?) available editors, whether you want to do that by uninstalling/installing VisualEditor or via user preferences is up to you. It is worth testing that the following works both with Parsoid as your default parser and with the legacy parser.

1. Go to an non-existing page on your wiki, eg [[Non Existing Page]]. Select a language variant in the drop down (eg Igpay Atinlay). Then click on 'Create' and/or 'Create source'. Type some text with language converter markup, eg:

-{raw text} Pig Latin -{N|sr-ec}-

Click 'show preview'. The preview *should* appear as: raw text Igpay Atinlay српски (ћирилица) (ie, rendered in the selected variant). If you then save the page it /should/ also display in your selected variant.

2. Open an existing page. Select a non-default variant. As before, edit the page and confirm that the previews are in the proper variant, and then save the page and confirm that the page is in the proper variant (and that the drop down dialog matches the selected variant).

3. For bonus credit, do all of the above but with ?uselang=es (or some other language) on the URL command line. The user interface language should remain consistently Spanish throughout the edit, preview, and display-after-edit.

(you'll probably need Ensure parse-after-edit and previews match user settings (1272835) for all the steps to work properly with Visual Editor.)

@Diskdance's Variant Ally currently does some of the query parameter patching on zhwiki. I suspect it may need adaptations.
