node.js - Mocha test with data layer? -

i have question data layer in mocha/should test.

i allready have test.js contains mocha/should test.

the following im supposed this: write tests in mocha/should + sufficient mock-framework (nock job) should verify data layer call correct urls in rest api. tests should not invoke underlying rest api.

i have simple rest api crud. im not sure put in data layer?

//setup tests var var testuserequals = { url: "http://localhost:3000/api/users/:email", method: 'get' };  var testuseremail = { url: "http://localhost:3000/api/users/ultricies.adipiscing@utaliquam.ca", method: 'get', json: true };  //and test email:     describe('get specific user email', function(){     it('should return specific user', function(done){          //facade         request(testuseremail, function(err, res, body){             if(err){                 throw err;             }             body.email.should.equal("ultricies.adipiscing@utaliquam.ca");             done();         })     }) }) 

in users.js have emails , password:

module.exports = [  { "email": "ultricies.adipiscing@utaliquam.ca", "password": "0b25a444-d4bc-8819-3632-d38626487588"  }] 

and data layer, call control.js

var user = require('./users');  function getuser(email, callback){ user.finduser(function(err, user){     if(err)     return callback(err);     console.log(user); }) }; 

im little lost on datalayer should contain, , couldn´t find info anywhere.
