Sessions

Sessions are available by using the same phantom-instance. Calling the method close will also close the session.

describe('test phantom-cheerio sessions.', function () {

    this.timeout(10000); //npmjs.com is too slow for default timeout

    it('instance should use existing session', function (done) {

        var phantomCheerioWithUA = require('phantom-cheerio')({

        });

        var credentials = {
            userName: "userName",
            password: "password",
            login: true
        };

        phantomCheerioWithUA.post('https://www.npmjs.com/login', credentials, function (status) {
            phantomCheerioWithUA.open('https://www.npmjs.com/', function ($) {
                assert.equal($('#user-info li.username a').text(), 'userName', 'logged in username should be present.');
                phantomCheerioWithUA.close();                    
                done();
            });
        });

    });
