无法使用 sinon 模拟护照身份验证('local')方法

Cannot mock passport authenticate('local') method with sinon

我正在尝试模拟 passport.authenticate('local'):

 app.post('/login', passport.authenticate('local'), (req, res, next) => {console.log('should enter');})

我正在使用 Sinon,但该方法不会在登录路由中执行 console.log

beforeEach(function (done) {
      aut = sinon.stub(server.passport, 'authenticate').returns(() => {});
      server.app.on('appStarted', function () {
        done();
      });
    });

afterEach(() => {
  aut.restore();
});

describe('Login', () => {
  it('should login', (done) => {
    chai.request(server.app)
      .post('/login')
      .send({
        username: 'user',
        password: 'pas'
      })
      .end(function (error, response, body) {
        return done();
      });
  });
});

此外, 当我将 mock 放入真实的 passport.authenticate('local') 时,如下所示:

app.post('/login', () => {}, (req, res, next) => {console.log('should enter');})

它仍然没有进入路由,这意味着 sinon callFake 根本没有帮助。只有当我删除

passport.authenticate('local')

/login 路由 'should login' test 进入路由。

在beforeEach中实现sinon

let server = require('../../../app.js');
let expect = chai.expect;
chai.use(chaiHttp);

var aut;
beforeEach(() => {
  aut = sinon.stub(server.passport, 'authenticate').returns((req, res, next) => next());
});

app.js

const app = express();

middleware.initMiddleware(app, passport);

const dbName = 'dbname';
const connectionString = 'connect string';

mongo.mongoConnect(connectionString).then(() => {
        console.log('Database connection successful');
        app.listen(5000, () => console.log('Server started on port 5000'));
    })
    .catch(err => {
        console.error('App starting error:', err.stack);
        process.exit(1);
    });

// If the Node process ends, close the Mongoose connection
process.on('SIGINT', mongo.mongoDisconnect).on('SIGTERM', mongo.mongoDisconnect);

register.initnulth(app);

login.initfirst(app, passport);
logout.initsecond(app);


module.exports = app;

您似乎想要使用中间件回调,它什么都不做,只是让请求由后面的中间件处理。这样的回调将是:

(req, res, next) => next()

中间件必须调用 next() 才能让请求继续由后面的中间件处理。所以你应该像这样设置你的存根:

aut = sinon.stub(server.passport, 'authenticate').returns((req, res, next) => next());
