如何在超测失败时打印请求日志（如请求 url、请求正文、请求 queryParam）？

Question

我想在 Supertest 预期失败的失败详细信息下方打印或控制台日志 对于以下成功请求，无需在成功时打印任何内容

const result = await request(dummy_url).get("repos/Microsoft/TypeScript/pulls")
      .set("user-agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:87.0) Gecko/20100101 Firefox/87.0")
      .expect(200)
      .then(response => {
        console.log("success");
        console.log(response);
        return response;
      }).catch(error => {
        console.log("error");
        // console.log(error);
        return 2;
      })
    console.log(result)
    done();

如果失败，假设我将 url 修改为 dummy 而不是 pull， 我需要知道请求 url、path parma 和 request body（如果有的话），

目前尝试以上述方式添加它只会出现以下错误

Error: expected 200 "OK", got 404 "Not Found"

注意事项， 我在 Typescript 中使用它，在 async 函数中，认为这不是一个阻塞器。

经过多次尝试和尝试，我想出了一个记录请求详细信息的函数，我将 supertest 的响应与预期的状态代码一起传递。 失败时，该函数将记录请求和响应的详细信息，如路径参数、查询参数、请求正文

import SuperTest from "supertest";
export const checkStatusCode = (res: any, expectedStatus: any = 200): SuperTest.Response => {
  if (res.status === expectedStatus) {
    return res
  };
  const error = res.error;
  const reqData = JSON.parse(JSON.stringify(res)).req;
  throw new Error(` 
  request-method  : ${JSON.stringify(reqData.method)} 
  request-url     : ${JSON.stringify(reqData.url)}
  request-data    : ${JSON.stringify(reqData.data)}
  request-headers : ${JSON.stringify(reqData.headers)}
  reponse-status  : ${JSON.stringify(res.status)}
  reponse-body    : ${JSON.stringify(res.body)}
  `
  );
};

在 jest 测试文件中的使用

describe("Jest - Api - user", () => {
  it("Verify POST ", async () => {
    const res = await request(url.someurl)
      .post("/dummy")
      .set("Authorization", authToken)
      .send(updateThirdParty)
    checkStatusCode(res, 200)
  })
})

该解决方案的灵感来自supertest github issue 中的建议之一。 感谢sakovias。 注意：这是记录数据的函数，我们仍然可以将其作为期望本身的包装器，我将作为单独的线程发布。
