NodeJS中axios和supertest的区别

问题描述

Axios 和 Supertest 都可以向服务器发送 HTTP 请求.但是为什么Supertest用于测试而Axios用于练习API调用?

Both Axios and Supertest can send HTTP requests to a server. But why is Supertest used for testing while Axios is used for practice API calls?

推荐答案

使用 Supertest 而不是像 Axios(或 Supertest 包装的 Superagent)这样的普通请求库:

There are two reasons to use Supertest rather than a vanilla request library like Axios (or Superagent, which Supertest wraps):

1. 它为您管理启动和绑定应用程序，使其可用于接收请求:

1. It manages starting and binding the app for you, making it available to receive the requests:

您可以将 http.Server 或 Function 传递给 request() - 如果服务器尚未侦听连接，然后它绑定到临时端口，因此无需跟踪端口.

没有这个，你就必须启动应用程序并自己设置端口.

Without this, you'd have to start the app and set the port yourself.

它添加了 expect 方法，它允许您对响应进行很多常见的断言，而不必自己写出来.例如，而不是:

It adds the expect method, which allows you to make a lot of common assertions on the response without having to write it out yourself. For example, rather than:

// manage starting the app somehow...

axios(whereAppIs + "/endpoint")
  .then((res) => {
    expect(res.statusCode).toBe(200);
  });

你可以写:

request(app)
  .get("/endpoint")
  .expect(200);
