Question

I m试图为APIC末点撰写一些单位测试,并在Javadspew/超标上决定。我走了基本坡道,但处理具体问题,以检查应对措施。我想把尸体捆绑起来,检查预期的外地回报是否正确。我在网上看到的多数东西都使用这一方法,但在我尝试时总是通过这种方法,即便在我进入价值观时,我知道在初生中还不存在。任何建议? 这里是我的法典:

describe( GET category , function () {
    it( response w/ only injury returned , function () {
        request( endpoint )
            .get( path )
            .set( header ,  token )
            .expect(200)
            .then(response => {
                console.assert(response.body, "Baseball")
            })
    })
});

I have also tried changing the .then to .expect, with same results. If I do response.body.specificFieldinBody I get similar results. Any help?

Answer 1

你可以这样做——使用<代码>then syntax,但我想使用Supertest assertion syntax。

This mean, use response.body.should.have.property("Baseball"); instead of console.assert(response.body, "Baseball") (Baseball is your special field).

或我的建议是制定重新使用守则: 下面的<代码>expects节规定追索功能。

const isIncludeField = function (fieldName) {
  return function (res) {
    res.body.should.have.property(fieldName);
  };
}

describe( GET category , function () {
  it( response w/ only injury returned , function () {
    request( endpoint )
      .get( path )
      .set( header ,  token )
      .expect(200)
      .expect(isIncludeField( Baseball )) // 
      .end(done); // call done callback
  })
});

我看到三个问题:

<代码>console.assert(response.one, “Baseball”, 仅检查response. .one 是真理。 <代码>Baseball>只是以下信息:如印有t(即Assertion : Baseball)。你也许会期待
```
console.assert(response.body.Baseball, "body.Baseball should be defined")
```
或您可能希望指出,某一关键数值等于>“Baseball”;例如,
```
console.assert(response.body.injury === "Baseball", "body.injury ===  Baseball ")
```
www.un.org/Depts/DGACM/index_french.htm 仅记录未果,可能won t becred/a>,由任何测试图书馆接收(Mocha, Jest)。我建议使用诸如Chai、Jest的建筑主张或至少是Node s本地的asse等断言图书馆,因此测试将显示失败。

<代码>request(终点) 退回允诺。如果测试套是用来评估试样的超常性质,那么,它会给你一个即时的通行证,而实际上却没有任何说法。使用<代码>return request ( endpoint ),以确保测试套期等待承诺链解决和发现任何说法。

Marking your test async helps reduce the footgun factor and is generally cleaner than .then() or callbacks (less nesting). Here s a complete example you can run with npx mocha server.test.js.

server.test.js:

const assert = require("assert");
const request = require("supertest");
const app = require("./server");

describe("GET category", () => {
  it("response with only injury returned", async () => {
    const response = await request(app).get("/path");
    assert(response.status === 200);
    assert(response.body.injury === "Baseball");
  });

  // ... or use supertest s assertions:
  it("response with only injury returned (alternate approach)", () => {
    return request(app)
      .get("/path")
      .expect(200, {injury: "Baseball"});
  });
});

<编码>server.js:

const express = require("express");
const app = express();

app.get("/path", (req, res) => res.json({injury: "Baseball"}));

module.exports = app;
