Question

所以当我测试视图是否有这个字符串时，我的所有其他测试都在工作，除了这个。问题是我收到一条错误消息，指出被调用的方法是null，但是当我访问页面时它正在工作。

错误讯息：

测试

public function an_admin_can_view_all_orders_with_their_status()
{
    $this->withoutMiddleWare();

    StoreSession::setMyStore($this->store->code);

    $orders = factory(CompletedOrder::class, 30)->create(['store_id' => $this->store->id]);

    foreach ($orders as $order) {
        factory(CompletedOrderItem::class, 5)->create(['completed_order_id' => $order->id]);
    }

    $response = $this->call("GET", route('list_completed_orders'));

    foreach ($orders as $order) {
        $response->assertSee($order->invoice()->getCode());
    }
}

控制器：

public function index()
{
    $store = StoreSession::getMyStore();

    $completedOrders = CompletedOrder::where('store_id', $store->getId() )->get();

    foreach ($completedOrders as $order) {
        Log::info($order->invoice()->getCode());
    }

    return view('store-manager.order-tracking.index', compact('store', 'completedOrders'));
}

提前致谢。

使用assertsee时，Laravel在null上调用成员函数
