Hey, since 2.8.4 caused by https://github.com/composer/composer/pull/12233 `InstalledVersions::reload` does nothing anymore. What we do in our unit tests: ```php InstalledVersions::reload([ 'root' => $before['root'], 'versions' => [ 'shopware/storefront' => [ 'version' => '1.0.0', 'dev_requirement' => false, ], ], ]); InstalledVersions::isInstalled('shopware/storefront'); // always false ``` It seems to load since that PR is always the real installed.php, instead of letting us overwrite it
