我用express编写了一个NodeJS应用程序代理了一些外部API调用.所以我正在尝试使用Mocha和Sinon编写单元测试.我的目标是测试应用程序没有任何互联网连接,所以我试图模拟https请求并返回模拟回复.
我遇到了一个问题,我无法找到适合我案例的示例或教程.我的节点应用程序在端口8081上侦听http请求,然后将它们代理到另一个站点.我想测试我的应用程序而不必将请求实际发送到那些外部服务器.我在下面尝试它,我把我要发送的json回复发送回server.respondsWith()函数.
我是否以正确的方式与chai进行ajax调用?或者我应该以某种方式在我的应用程序内发送请求.任何帮助表示赞赏.
var assert = require('assert'); var chai = require('chai'); var spies = require('chai-spies'); var chaiHttp = require('chai-http'); var https = require('https'); var should = chai.should(); var expect = chai.expect; var sinon = require('sinon'); chai.use(spies); chai.use(chaiHttp); describe('Car Repository',function() { var server; before(function() { server = sinon.fakeServer.create(); }); after(function() { server.restore(); }); var url = 'http://127.0.0.1:8081'; it('should succeed and return a list of cars',function(done) { server.respondWith('POST','https://api.sandBox.cars.com/v2/token_endpoint',JSON.stringify({"access_token":"1t3E4IykfpJAbuFsdfM2oFAo5raB5vhfOV0hAYe","token_type":"bearer","expires_in":604800})); server.respondWith('GET',url+'/cars',JSON.stringify({'test':'this works'})); chai.request(url) .get('/cars') .end(function(err,res) { if (err) { throw err; } res.should.have.status(200); res.body.should.have.property('test'); console.log(res.body); done(); }); }); });
解决方法
查看
Nock库.它完全符合您的要求.
Nock is an HTTP mocking and expectations library for Node.js
Nock can be used to test modules that perform HTTP requests in isolation.
For instance,if a module performs HTTP requests to a CouchDB server or makes HTTP requests to the Amazon API,you can test that module in isolation.
