Question

我需要测试一个需要响应作为参数的函数，我正在使用mocha并在带有快速框架的节点环境中进行续集。我的代码被固定在多个文件中，但是我只需要测试superactivator距离。这些是我的文件：

route.js

const express = require('express');
const router = express.Router();

const rcv_pcController = require('../controllers/rcv_pc.controller');

router.post('/', rcv_pcController.switchMode);

module.exports = router;

rcv_pc.controller.js

const superActivator = require('../helpers/superactivator');
...

const switchMode = async (req, res) => {
    ...

    switch (tipo) {
        case "1":
            {
                if (modo == "1") {
                    superActivator.checkLicense(license, hwId, oem, expire, nowDate, ip, allowedSerials, res)
                }
                else if (modo == "2") {
                    superActivator.generateLicense(license, hwId, reqCode, nowDate, ip, res);
                }
                else if (modo == "3") {
                    superActivator.registerLicense(license, hwId, reqCode, nowDate, customerName, referenteName, referentePhone, ip, res)
                }
                break;
            }
    }
}

module.exports.switchMode = switchMode;

superactivator.js

const repository = require('../repositories/rcvpc.server.repository');

    registerLicense(license, hwId, reqKey, pcDate, customerName, referenteName, referentePhone, ip, res) {
        pcRepo.findOne(hwId)
            .then((pc) => {
                let pcId = '';
                if (!pc) {
                    const data = {

                    }).catch(err => res.send(err.errors))
            }).catch(err => res.send(err.errors));
    }

}

...

const superActivator = new SuperActivator(licCheckResult);

module.exports = superActivator;

为清楚起见，我忽略了所有Superactivator类方法。这是我的测试代码：

superactivator.spec.js

...

const superactivator = require('../helpers/superactivator');

...

describe('checkLicense()', function () {
    it('sks ', async function () {
        // here I mock the request.body data
        const ip = '127.0.0.1';
        const license = "A2YyLM8i3G7feJt7Hlm8hxlYk";
        const hwId = "123490EN40";
        const oem = 12;
        const expDate = "2019-10-10";
        const nowDate = null; // "2018-09-05"
        const allowedSerials = null;

        const foundSks = await superactivator.checkLicensecheckLicense(license, hwId, oem, expDate, nowDate, ip, allowedSerials, res)
        assert.equal(foundSks, '1');
    });
});

我得到了错误

ReferenceError：未定义res

在上下文中。（test \ superactivator.spec.js：23：130）

因为我的测试文件中没有res。我怎么解决这个问题？我只需要模拟响应以检查返回的值即可。

感谢您的帮助！

您可以使用 Sinon 来帮助您侦察/存根res，例如：

...

const superactivator = require('../helpers/superactivator');
const sinon = require('sinon'); // ----> use sinon
...

describe('checkLicense()', function () {
    it('sks ', async function () {
        // here I mock the request.body data
        const ip = '127.0.0.1';
        const license = "A2YyLM8i3G7feJt7Hlm8hxlYk";
        const hwId = "123490EN40";
        const oem = 12;
        const expDate = "2019-10-10";
        const nowDate = null; // "2018-09-05"
        const allowedSerials = null;
        const res = { 
          send: sinon.spy() // --> create spy for res.send method
        }

        const foundSks = await superactivator.checkLicensecheckLicense(license, hwId, oem, expDate, nowDate, ip, allowedSerials, res)
        assert.equal(foundSks, '1');
    });
});
