如何以多种方式调用或存根相同的导入函数 [英] How to call or stub with same imported function with multiple ways

问题描述

在控制器中，我导入了配置文件，用于获取用户ID的路径和秘密路径位置，并导入了auth文件，用于获取基于我重定向到某个端点的用户ID名称和密码值。但当我编写测试用例时，如何使用存根传递或获取所有细节。你能帮忙吗？

Controler.ts

import { userConf } from './conf';
import {userSec} from './auth'

 export function userInfo(req: Request, res: Response) {
const path='test:path';
const path1='test:path1'
const userID = userConf(path); //user/Id
const userPass=userConf(path1); // user/pass
const secId=userSec(userID); // raj
const secPass=userSec(userPass) // Otersg
const url=`https://mapuser.com?userId=${secId}&usersec=${secPass}`;
res.redirect(302,url);
}

Details.json

{
"test":{
    "path":"user/Id",
    "path1":"user/pass"
 }
}

conf.ts

export function userConf(path) {
  return 'implementation for getting path';
}

Auth.ts

export function usersec(path) {
  return 'implementation for getting values';
}

test.spec.ts

import sinon from 'sinon';
import proxyquire from 'proxyquire';

 describe('should redirect', () => {
 it('should pass with all valid', () => {
  const getpath = sinon.stub().returns('test:path');
  const getsecId = sinon.stub().returns('ram');
  const urlctl = proxyquire('./controller', {
  './conf': {
    userConf: getpath,
  },
  './auth': {
    userSec: getsecId,
  },
});
const req = {};
const res = { redirect: sinon.stub() };
urlctl.getId(req, res);

sinon.assert.calledWithExactly(res.redirect, 302, 'https://mapuser.com? 
userId=raj&usersec=Otersg');
 });
 });

推荐答案

不清楚您要尝试实现的目标。如果您想要创建可以根据不同参数做出不同反应的存根。您可以使用stub.withArgs(arg1[, arg2, ...])。

例如

controller.ts：

import { Request, Response } from 'express';
import { userConf } from './conf';
import { userSec } from './auth';

export function userInfo(req: Request, res: Response) {
  const path = 'test:path';
  const path1 = 'test:path1';
  const userID = userConf(path);
  const userPass = userConf(path1);
  const secId = userSec(userID);
  const secPass = userSec(userPass);
  const url = `https://mapuser.com?userId=${secId}&usersec=${secPass}`;
  res.redirect(302, url);
}

controller.spec.ts：

import sinon from 'sinon';
import proxyquire from 'proxyquire';

describe('should redirect', () => {
  it('should pass with all valid', () => {
    const getpath = sinon.stub();
    getpath.withArgs('test:path').returns('fake user id');
    getpath.withArgs('test:path1').returns('fake user pass');

    const getsecId = sinon.stub();
    getsecId.withArgs('fake user id').returns('raj');
    getsecId.withArgs('fake user pass').returns('Otersg');

    const urlctl = proxyquire('./controller', {
      './conf': {
        userConf: getpath,
      },
      './auth': {
        userSec: getsecId,
      },
    });
    const req = {};
    const res = { redirect: sinon.stub() };
    urlctl.userInfo(req, res);

    sinon.assert.calledWithExactly(res.redirect, 302, 'https://mapuser.com?userId=raj&usersec=Otersg');
  });
});

测试结果：

  should redirect
    ✓ should pass with all valid (239ms)


  1 passing (243ms)
