node.js - chai-webdriver ( Node ) ... 描述不是一个函数

Question

我不断收到描述不是函数的错误。我该如何解决这个问题

// Require chai.js expect module for assertions
var chai = require('chai');
var expect = require('chai').expect;
chai.use = require ('chai-as-promised')
// Application Server
var serverUri = '0.0.0.0:3000';

// Official selenium webdriver testing setup
var webdriver = require('selenium-webdriver');

describe('basic test', function () {
    var driver;
    before(function(){
        // Start of test use this
        driver = new webdriver.Builder().
        withCapabilities(webdriver.Capabilities.chrome()).
        build();
        console.log("Selenium Webdriver Chrome Started");
    });

    after(function(){
        // End of test use this.
        driver.quit();
    });

    it('should be on correct page', function (done) {
        this.timeout(10000);
        driver.get(serverUri);
        driver.getTitle().then(function(title) {
            expect(title).to.equal('Some String Here');
            done();
            console.log("Selenium Webdriver Chrome Shutdown");
        })
    });
});

运行后得到的错误是:

describe is not a function

Answer 1

您忘记需要 mocha(假设您安装了它)..

尝试添加

const { 描述、it、之前、之后 } = require('mocha');
