But if modules are defined in <code>protected static $modules </code>, they need not to be explicitly installed in <code>protected function setUp()</code>.</p>
<p>So basically remove <code>$this->container->get('module_installer')->install(self::$modules);</code> from <code>protected function setUp()</code></p>
