javascript - Unit Testing with ExpresJS (Confused) -

so trying unit test expresjs routes. looks somthing

server.js

var boards = require('./routes/boardsroute.js'); app.get('/api/v1/boards/:id', boards.getboard); 

boardroutes.js

exports.getboard = function(req, res) {   boardmodel.find({         name: 'kanban board'     }, function(err, columns) {     if (!err) {         return res.send(columns);     } else {         return console.log(err);     } }); return res.send(board); }; 

i mock out boardmodel call mongoose model (aka database call). assume unit tests should not making calls database , have no server running.

should testing getboards seperatly server.js app.get() call. (as these requests apt.get covered integration tests/e2e tests , http requests)

all documentation , frameworks can see either have have express server running in order unit test route , particular exports.getboard.

things have tried ,

use sinon.js mock fakeserver test http request , method getboard.

use superagent , super test make requests out server. (i uncomfortable unit tests should not have server runnig).

i trying use mocha test these routes.

any great clear confusion.

i test route wired correctly first, test call route expect.

to test route here's 1 way it. create routes module wires routes:

var routes = {};                                                                                                             routes.create = function(app) {                                                                                                                                                                                         app.get('/api/v1/boards/:id', boards.getboard); }  module.exports = routes; 

you can mock app object , check method gets called correctly. (i tend use sinon.js this.) create method need called app module:

var app = express(); ... // set express routes.create(app); 

now can focus on testing getboard on own other module.
