How to use the @aws-sdk/protocol-http.HttpResponse function in @aws-sdk/protocol-http

it("should prefer the request ID from the standard header", () => {
    expect(
      extractMetadata(new HttpResponse({
        ...httpResponseOptions,
        headers: {
          "X-Amz-Request-ID": "id",
          "X-Amz-RequestId": "alt_id"
        }
      })).requestId
    ).toBe("id");
  });

it("should extract and downcase headers", () => {
    const response = new HttpResponse(httpResponseOptions);
    expect(extractMetadata(response).httpHeaders).toEqual({
      foo: response.headers.Foo,
      fizz: response.headers.Fizz,
      snap: response.headers.Snap
    });
  });

it("should extract the status code from responses", () => {
    const response = new HttpResponse(httpResponseOptions);
    expect(extractMetadata(response).httpStatusCode).toBe(response.statusCode);
  });

req.on("response", headers => {
        const httpResponse = new HttpResponse({
          statusCode: headers[":status"] || -1,
          headers: getTransformedHeaders(headers),
          body: req
        });
        resolve({ response: httpResponse });
      });

const req = (isSSL ? https : http).request(nodeHttpsOptions, res => {
        const httpResponse = new HttpResponse({
          statusCode: res.statusCode || -1,
          headers: getTransformedHeaders(res.headers),
          body: res
        });
        resolve({ response: httpResponse });
