Set all the configuration settings the test depends on

Shouldn't the guide also tell to explicitly set all the configuration settings globals a test assumes, via setMWGlobals? Otherwise the test will test those globals, rather than whatever it's supposed to test: a nightmare for everyone running tests on a true development checkout (rather than vanilla core), or changing configuration defaults.

Data Provider naming

I disagree with provideFoo being a better name than fooProvider. We are generally following the second on for Wikibase (and we actually have over twice as many data providers as core). Now that I noticed some people are using the former one because that is listed here, I will updated the Wikibase guidelines. I can only suggest the same is done here.

Peeking at SQL tables during PHP tests

Does anyone know why MediaWikiIntegrationTestCase only creates unittest_ SQL tables for some of the tables in the database and not all of them? I'm trying to spy on tables using HeidiSQL while step debugging and I observed this. Important tables such as page and user do not have an equivalent unittest_page, unittest_user, etc. Maybe @Daimona Eaytoy knows? I'm using Docker + MariaDB. Thanks. –Novem Linguae (talk) 16:17, 13 January 2024 (UTC)

I think MWIntegrationTestCase is supposed to clone all tables, cfr. ::setupDatabaseWithTestPrefix(). This seems to be the case in my local. Maybe you could try stepping through that method to see if there's anything wrong? Daimona Eaytoy (talk) 00:03, 14 January 2024 (UTC)

Thanks. Did some step debugging, everything looked OK. Then I figured out that it is using TEMPORARY tables, which are not viewable in the table list. Setting the .env variable PHPUNIT_USE_NORMAL_TABLES=1 turns this off. Will use that from now on. Thanks for helping me talk this out. –Novem Linguae (talk) 11:54, 14 January 2024 (UTC)
