This is weird since MW 1.34 does require the package that provides this class: https://github.com/wikimedia/mediawiki/blob/REL1_34/composer.json#L78

Perhaps the used PHPUnit version is causing problems

[s7eph4n]

Dunno. Works with master.
Could this be a problem with the used installation method (composer vs. download)?

Edit: Or a combination of the two?
