Sequelize extension to deal with data-mocking for testing
- it was tested with Sequelize 3.19.3 before 1.0.0
- it was tested with Sequelize 4.3.1 since 1.0.0.
- it was tested with Sequelize 5.3.0 since 2.0.0
**And you have to declare in your package.json the expected sequelize version**
It will use the sqlite database for mocked database, will recreate it for database.
Can be integrated with Mocha and Jasmine.
A sample of use:
````js
/**
* Test around the @{UserService}
*
* @module test/user/service
*/
'use strict';
const chai = require('chai');
const sinon = require('sinon');
const path = require('path');
const sequelizeMockingMocha = require('sequelize-mocking').sequelizeMockingMocha;
describe('User - UserService (using sequelizeMockingMocha) - ', function () {
const Database = require('../../lib/database');
const UserService = require('../../lib/user/service');
const UserModel = require('../../lib/user/model');
// Basic configuration: create a sinon sandbox for testing
let sandbox = null;
beforeEach(function () {
sandbox = sinon.sandbox.create();
});
afterEach(function () {
sandbox && sandbox.restore();
});
// Load fake data for the users
sequelizeMockingMocha(
Database.getInstance(),
path.resolve(path.join(__dirname, './fake-users-database.json')),
/* Or load array of files
[
path.resolve(path.join(__dirname, './fake-users-database.json')),
path.resolve(path.join(__dirname, './fake-candy-database.json')),
]
*/
{ 'logging': false }
);
it('the service shall exist', function () {
chai.expect(UserService).to.exist;
});
describe('and the method findAll shall ', function () {
it('exist', function () {
chai.expect(UserService.findAll).to.exist;
});
it('shall returns an array of user', function () {
return UserService
.findAll()
.then(function (users) {
chai.expect(users).deep.equals([{
'id': 1,
'firstName': 'John',
'lastName': 'Doe',
'age': 25,
'description': null
}]);
});
});
});
describe('and the method find shall ', function () {
it('exist', function () {
chai.expect(UserService.find).to.exist;
});
it('shall return a user if we can', function () {
let findByIdSpy = sandbox.spy(UserModel, 'findById');
return UserService
.find(1)
.then(function (user) {
chai.expect(findByIdSpy.called).to.be.true;
chai.expect(findByIdSpy.calledOnce).to.be.true;
chai.expect(findByIdSpy.calledWith(1)).to.be.true;
chai.expect(user).deep.equals({
'id': 1,
'firstName': 'John',
'lastName': 'Doe',
'age': 25,
'description': null
});
});
});
it('shall return null if not found', function () {
return UserService
.find(-1)
.then(function (user) {
chai.expect(user).to.be.null;
});
});
});
});
````
And the mocked data from the JSON file:
````JSON
[
{
"model": "user",
"data": {
"id": 1,
"firstName": "John",
"lastName": "Doe",
"age": 25,
"description": null
}
}
]
