Take an inside look at how PayPal is managing its test automation efforts, with Nemo: open source node.js-based Selenium-webdriver wrapper, and Applitools Eyes automated visual testing.

1. NemoJS'and'Applitools'Eyes
Visual'Tes*ng'with'node.js

2. Where%does%Nemo%
fit?

5. A"basic"JavaScript"selenium3webdriver"script:
var webdriver = require('selenium-webdriver'),
SeleniumServer = require('selenium-webdriver/remote').SeleniumServer;
var server = new SeleniumServer(pathToSeleniumJar, {
port: 4444
});
server.start();
var driver = new webdriver.Builder().
usingServer(server.address()).
withCapabilities(webdriver.Capabilities.firefox()).
build();
driver.get('https://www.paypal.com');

6. The$same$script$using$Nemo
var Nemo = require('nemo');
var nemo = Nemo(function () {
nemo.driver.get('https://www.paypal.com');
});

7. What%does%Nemo%do?
• provides*environment.aware*JSON*configura9on
• provides*plugin'API
• provides*access*to*the*webdriver*API

8. The$webdriver$API
exposed'as'nemo.driver'and'nemo.wd

9. Environment*aware*configura1on
• config.json"is"the"defaults"file
• add"overrides"based"on"NODE_ENV
• e.g."NODE_ENV=local"looks"for"local.json

10. Configura)on*protocols
• shortstop(handlers
• env:foo
• path:foo
• argv:foo
• config:foo.bar

13. Using&nemo*view
it('should execute high level functionality using flow modules', function (done) {
//login
nemo.driver.get(nemo.data.baseUrl);
util.waitForJSReady(nemo);
nemo.view.login.emailWaitVisible().sendKeys('me@mine.com');

14. DRY$pa'ern$(card$module)

Card.prototype.addFailure = function(number, type) {

module.exports = Card;

15. DRY$pa'ern$(navigate$module)
var util = require('../util');

};
Navigate.prototype.card = function() {
this.nemo.view.nav.cardLink().click();
return nemo.view.card.numberWaitVisible();
};
module.exports = Navigate;

16. DRY$pa'ern$(spec$usage)
it('should execute high level functionality using flow modules', function (done) {
navigate.loginFailure('fail@fail.com', '11111111');
navigate.loginSuccess('me@mine.com', '11111111');

bank.addFailure('1001001', '92929');
