It seems like $node->var->name can also be of type PhpParser\Node\Expr; however, parameter $name of PhpUnitGen\Model\ParameterModel::setName() does only seem to accept string, maybe add an additional type check?

The property name does not seem to exist on PhpParser\Node\Expr\Error.

        $parameter->setIsVariadic($node->variadic);

        if ($node->type !== null) {
            $this->typeNodeParser->invoke($node->type, $parameter);
        }
        if ($node->default !== null) {
            $this->valueNodeParser->invoke($node->default, $parameter);
        }

        $parent->addParameter($parameter);
    }
