We would like to remove DB access in non-database PHPUnit tests. As a first step, avoid database usage in tested code when possible. In particular: - In NameTableStoreFactory, avoid domain ID normalization if the provided ID is already false. - In SpecialDoubleRedirects, do not acquire a DB connection until it's needed (which is just one place). - Use editPage() in TitleDefTest instead of a DIY implementation, and add `@group Database` accordingly. - Avoid parsing titles in ContentHandler tests that don't need to parse titles. Among the many dependencies of parsing titles is the interwiki lookup, which requires DB access. - Also remove test cases that used the "Gadget" namespace; it doesn't exist in core, so these pages were actually in the mainspace. - Mock the database in CategoriesRdfTest. The only two methods that use the database were already being mocked. - Add `@group Database` to test classes that are intentionally using the Database, mainly via getTestUser().

MediaWiki PHPUnit tests
WARNING: Integration tests may be destructive and alter or remove parts of your local database. We try to use temporary tables where possible, but you must never run tests on a production server or on a wiki where you don't want to lose data.
Running tests
If you haven't already, run composer update (specifically without --no-dev) in the MediaWiki core directory. This will install PHPUnit.
To read about how to run specific tests, refer to:
https://www.mediawiki.org/wiki/Manual:PHP_unit_testing/Running_the_tests
Writing tests
