【Laravel】HTTPステータスコードの定数を使ってエラーを発生させる

目的

Laravelが用意しているHTTPステータスコードの定数を使用して、希望のエラーが発生させられるようにする。

使用例

HTTP_UNPROCESSABLE_ENTITYがHTTPステータスコードの定数

TestRequest

    protected function failedValidation(Validator $validator)
    {
        throw new HttpResponseException(response()->json([
            'errors' => $validator->errors(),
        ], JsonResponse::HTTP_UNPROCESSABLE_ENTITY));
    }

Postmanで実行すると422が返ってくる。
