快递:我不明白如何使用sinon

问题描述 投票:0回答:1

我有一个控制器方法:

registration(req, res) {
  if (!req.user) return res.status(401).send('Registration failed');

  const { user } = req;
  return res.status(201).json({ user });
},

我想测试使用我的假数据发送json的注册方法。

const { expect } = require('chai');
const sinon = require('sinon');
const authController = require(...);

describe('authController', () => {
  const USER = {
  email: '[email protected]',
  password: 'Test12345',
  confirm: 'Test12345',
  username: 'Test',
};

it('it should send user data with email: [email protected]', () => {
  const req = { user: USER };
  const res = {
    status: sinon.stub().returnsThis(),
    json: sinon.spy(),
  };

  console.log('RES: ', res); // I can't see the json data
  authController.registration(req, res);
  expect(res.json).to.equal(USER);
});

我检查了我的USER的数据进入控制器(req.user)。我试着用spy查看包含res的内容,但是没有找到我的USER数据我不明白如何在我的情况下使用sinon?

你几乎完成了测试。对于这种测试,我们可以使用Sinon的calledWith来检查被正确调用的函数和参数。

describe('authController', () => {
  const USER = {
    email: '[email protected]',
    password: 'Test12345',
    confirm: 'Test12345',
    username: 'Test',
  };

  it('it should send user data with email: [email protected]', () => {
    const req = { user: USER };
    const res = {
      status: sinon.stub().returnsThis(),
      json: sinon.spy(),
    };

    authController.registration(req, res);

    // this is how we check that the res is being called with correct arguments
    expect(res.status.calledWith(201)).to.be.ok;
    expect(res.json.calledWith({ user: USER })).to.be.ok;
  });
});

希望能帮助到你。
