Question

我有一个使用Express和Passport的应用。我在Passport中使用Google OAuth2策略。我有一些需要通过此策略登录的路线。

我目前正在与Mocha和Chai进行集成测试，但我不确定如何绕过或使用某些路由所需的OAuth2身份验证。

例如，这是我的一个测试：

it("should list a single item on /items/<id> GET", function(done) {                                                                             
  chai.request(server)
    .get('/items/' + id) 
    .end(function(err, res) {
      res.should.have.status(200);
      res.should.be.json;
      res.body.should.be.a('object');
      res.body.should.have.property('description');
      done();
    }); 
});

/items/:id

的路线

router.get('/items/:id', auth.isLoggedIn, function(req, res) {
  var item = getItem();
  res.json(item);
});

/items/:id需要登录。有没有办法绕过登录进行测试，或者模仿用户，我的集成测试会起作用？

我能用mocha chai chai-http nock和nock-github-oauth测试github OAuth /护照

nock-github-oauth存根令牌网址

还手动将github用户和电子邮件api调用与来自GitHub API文档的示例进行nock调用

这是我的auth_controller_spec.js

//During the test the env variable is set to test
process.env.NODE_ENV = 'test';

var chai = require('chai');
var chaiHttp = require('chai-http');
var should = chai.should();
var expect = chai.expect

var User = require.main.require('models/User');

// https://gist.github.com/branneman/8048520#7-the-wrapper
var app = require.main.require('app');

chai.use(chaiHttp);


function nockGitHubUserAPI(nock) {
  /**
   * Intercept `https://api.github.com:443/user` API Call.
   */
   nock('https://api.github.com:443')
    .filteringPath(/\/user.+/, '/user')
    .get('/user')
    .reply(200,

我想通过在我的mocha测试中的请求对象中模拟isAuthenticated来弄清楚如何使这项工作。

var chai = require('chai');
var chaiHttp = require('chaiHttp');
var server = require('../app');
var should = chai.should();

chai.use(chaiHttp);

// Allows the middleware to think we're already authenticated.
server.request.isAuthenticated = function() {
  return true;
}

describe('Items', function() {
  it('should list all items on / GET', function(done) {
    chai.request(server)
      .get('/')
      .end(function(err, res) {
        res.should.have.status(200);
        res.should.be.json;
        // more tests...
        done();
      });
  });
});

如果需要，您可以使用自己的方法绕过它，但最好也是测试登录，然后您可以测试要求用户登录的功能。

我之前从未使用过Chai，但你可能会做同样的事情：

var user = null;

it("should log the user in", function(done) {                                                                             
  chai.request(server)
    .post('/login', userCredentials) 
    .end(function(err, res) {
      res.should.have.status(200);
      user = res.body;
      done();
    }); 
});
