As a Wikibase developer, I want to run the test suite locally without errors, to see if there’s something wrong with my changes or not.
Problem:
With $wgUseInstantCommons = true in my LocalSettings.php, this test fails:
1) Wikibase\Lib\Tests\Formatters\WikibaseValueFormatterBuildersTest::testNewFormatter with data set "html commons inline image" ('CommonsMedia', 'text/html; disposition=verbose', ValueFormatters\FormatterOptions Object (...), DataValues\StringValue Object (...), '@^<div.*>.*<a.*href="https://...iv>$@s')

===Workaround:
$wgUseInstantCommons = !defined( 'MW_PHPUNIT_TEST' ); // T343133
Notes:
This has happened before, see T268890: Some Wikibase API tests fail if Instant Commons is enabled (I blatantly reused parts of the task description).
