If you want to use the real req and res objects, you have to send real requests to the server. However this is much easier than you might think. There are a lot of examples at the express github repo. The following shows the tests for req.route

var express = require('../')
  , request = require('./support/http');

describe('req', function(){
  describe('.route', function(){
    it('should be the executed Route', function(done){
      var app = express();

      app.get('/user/:id/edit', function(req, res){

        // test your controllers with req,res here (like below)

        req.route.method.should.equal('get');
        req.route.path.should.equal('/user/:id/edit');
        res.end();
      });

      request(app)
      .get('/user/12/edit')
      .expect(200, done);
    })
  })
})
