i am using Express js and Mysql for my application, now i want to start unit testing. I have written this code:
var request = require('supertest');
var server = require('./app');
var chai = require('chai');
var chaiHttp = require('chai-http');
var server = require('./app');
var should = chai.should();
chai.use(chaiHttp);
describe('loading express', function () {
it('responds to /', function testSlash(done) {
request(server)
.get('/')
.expect(200, done);
});
it('404 everything else', function testPath(done) {
request(server)
.get('/foo/bar')
.expect(404, done);
});
it('responds to /customers/getCustomerData', function testPath(done) {
request(server)
.get('/customers/getCustomerData?id=0987654321')
.end(function(err, res){
res.should.have.status(200);
res.body.should.be.a('object');
res.body.status.should.equal("success");
res.body.data.customerId.should.equal("0987654321");
done();
});
});
});
This code is working properly but it makes connection to database and checking all the test cases which i have written, but this is called integration testing i have to do unit testing using mock database. How can i achieve this mocking of database?
