Testing an MEVN Application Chapter 9

Let's create a new file, called movies.spec.js, inside the test/units folder:

var movies = require("./../../../controllers/movies.js");

var expect = require('chai').expect;

describe('controllers.movies.js', function(){

it('exists', function(){

expect(movies).to.exist

})

})

This test code simply checks whether the controller exists or not, which should pass

when we run the following command:

$ mocha test/unit/controllers/movies.spec.js

This command runs the tests for our controller/movies.js and should pass with the

following output:

Let's first write a test for a simple method. Let's create a request that responds with just an

object with a name. In movies.js, let's add the following code to create a dummy API:

const Movie = require("../models/Movie");

const passport = require("passport");

module.exports.controller = (app) => {

// send a dummy test

app.get("/dummy_test", function(req, res) {

res.send({

name: 'John'

})

})

In the preceding code, we have a simple method that returns an object.
