[英]NodeJS Chai Mocha response undefined
I create my test code using typescript and run my test using mocha (mocha --timeout 10000)我使用 typescript 创建我的测试代码并使用 mocha (mocha --timeout 10000) 运行我的测试
The following is my code:以下是我的代码:
import chai from 'chai';
import chai_http from 'chai-http';
chai.use(chai_http);
describe('upload', () => {
beforeEach((done) => {
done();
});
describe('/POST upload', () => {
it('it should not POST a book without pages field', (done) => {
let book = {
title: "Test"
}
chai.request('http://192.55.55.19:3000')
.post('/upload')
.set('Content-Type', 'application/json')
.send(book)
.end((err, res) => {
console.log(`\ntesting3: ${JSON.stringify(res.status)}`);
res.should.have.status(200);
done();
});
});
});
});
Clearly, res.status exist.很明显,res.status 是存在的。
Why res.should.have.status produce the undefined error?为什么 res.should.have.status 会产生未定义的错误?
Actually, I tried other things such as should.have.property nad I got undefined as well.实际上,我尝试了其他东西,比如 should.have.property nad 我也没有定义。
Thanks in advance提前致谢
From the assertion styles#should , Chai extends each object with a should
property after calling chai.should()
.从断言 styles#should中,Chai 在调用chai.should()
之后用一个should
属性扩展了每个 object。
Which means chai will add should
property to Object.prototype
after calling chai.should()
.这意味着 chai 将在调用chai.should()
后将should
属性添加到Object.prototype
。
The
should
interface extendsObject.prototype
to provide a single getter as the starting point for your language assertions.should
接口扩展Object.prototype
以提供单个 getter 作为语言断言的起点。
Eg例如
const chai = require('chai');
const chaiHttp = require('chai-http');
chai.use(chaiHttp);
chai.should();
describe('71144510', () => {
it('should pass', () => {
const res = { status: 200 };
res.should.have.status(200);
});
});
