Question

我需要先调用API请求（发布 lib.js），然后在 it 中检查结果。

无论我每次尝试执行的操作是什么，都先完成它，然后再完成 before 和 res 变量为空，如您在输出的开始-右下方带有井号的毫秒。

test.js

const lib = require('../lib/lib.js');
global.serverurl = process.env.SERVERURL;

describe('Template Scenario', function () {

    global.loginData = require('../data/template.json');

    describe('Login user', function () {

        var res;

        before(function () {
            res = lib.post('/rest/security/login/', {username: loginData.username, password: loginData.password});
        });

        it('should return right status code', function () {
            console.log('###########################'+Date.now());
            console.log(JSON.stringify(res));
            res.should.have.status(200);
        });

lib.js

const chai = require('chai');
chai.use(require('chai-http'));

exports.post = function (api_endpoint, request_body) {
    return chai.request(serverurl)
    .post(encodeURI(api_endpoint))
    .send(request_body)
    .then(function (r) {
        console.log('***************************'+Date.now());
        console.log(JSON.stringify(r));
    });
}

输出

  Template Scenario
    Login user
###########################1571734950189
{}
      1) should return right status code


  0 passing (59ms)
  0 pending
  1 failing

  1) Template Scenario
       Login user
         should return right status code:
     AssertionError: expected {} to have keys 'status', or 'statusCode'

已解决

当我将之前更改为异步，并在发布功能中删除了然后时，它可以正常工作。

test.js

const chai = require('chai');
const should = chai.should();
const lib = require('../lib/lib.js');
global.serverurl = process.env.SERVERURL;

var res;

describe('Template Scenario', function () {

    global.loginData = require('../data/template.json');

    describe('Login user', function () {

        before(async function () {
            res = await lib.post('/rest/security/login/', {username: loginData.username, password: loginData.password});
        });

        it('should return right status code', function () {
            res.should.have.status(200);
        });

lib.js

const chai = require('chai');
chai.use(require('chai-http'));

exports.post = async function (api_endpoint, request_body) {
    return chai.request(serverurl)
        .post(encodeURI(api_endpoint))
        .send(request_body);
}

输出

  Template Scenario
    Login user
      ✓ should return right status code
      ✓ should return correct Json schema


  2 passing (97ms)

摩卡（mocha）-为什么before（）尚未在“ before”之前完成，我该怎么做？
