Continuous Testing in the Cloud

Using Selenium, Sauce Labs, GitHub, and Travis-CI

What is Continuous Integration?

“Continuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early.”

http://www.thoughtworks.com/continuous-integration

Our Continuous Integration Process1. Create automated functional tests with Selenium

2. Our functional tests will run on Sauce Labs’ hosted browsers

3. Push our code changes to our hosted repository in GitHub

4. Our pushes will trigger a build run by the Travis-CI service which will run our tests on Sauce

Using Selenium for our Tests

What is Selenium?“Selenium, also known as Selenium 2 and WebDriver, is a UI automation toolkit used by software developers and QA engineers to test their web application on different web browsers. ”

— Satya Avasarala, Selenium WebDriver Practical Guide

Working with Selenium Tests

WebDriver driver = new FirefoxDriver();driver.get("https://www.google.com/");driver.findElement(By.id("gbqfq")).click();driver.findElement(By.id("gbqfq")).sendKeys("sauce labs");

Selenium interacts with browser apps, like this Google search:

Demo

Using Sauce for our Test Runs

Sauce supports just about any platform you need for your test runs!

Configuring Tests for Sauce WebDriver driver = new FirefoxDriver();driver.get("https://www.google.com/");driver.findElement(By.id("gbqfq")).click();driver.findElement(By.id("gbqfq")).sendKeys("sauce labs");

RemoteWebDriver driver = new RemoteWebDriver(new URL(“http://user:key@ondemand.saucelabs.com:80/wd/hub”),caps);

DesiredCapabilities caps = new DesiredCapabilities();caps.setCapability("browserName", “firefox");caps.setCapability("version", "22");caps.setCapability("platform", "LINUX");

For Sauce we replace the standard WebDriver with RemoteWebDriver:

Selenium interacts with browser apps, like this Google search:

And then we add our desired browser and platform:

Using GitHub for our Project

What is GitHub?“GitHub is a web-based hosting service for software development projects that use the Git revision control system. GitHub offers both paid plans for private repositories, and free accounts for open source projects. ”

— http://en.wikipedia.org/wiki/GitHub

Using Travis for our Builds

What is Travis-CI?“Travis-CI is a hosted, distributed continuous integration service used to build and test projects hosted at GitHub. Travis-CI automatically detects when a commit has been made and will try to build the project and run tests.”— http://en.wikipedia.org/wiki/Travis_CI

Configuring Travis for Sauce

gem install travis

travis init

travis encrypt SAUCE_USERNAME=your_sauce_username --addtravis encrypt SAUCE_ACCESS_KEY=XXXXXXXXXXXXXXXXX --add

Next, initialize your project for use with Travis CI:

First, install the Travis gem locally:

We need to encrypt our credentials for safe use in GitHub:

language: java

jdk:- oraclejdk7

env: global: - secure: HOTmOq6r+fjDDvr7gzETG7rS9IQtZ7QQ= - secure: NFM+4hE1VdaGs/lhaiVdn9Vi9P5L8Nb2t=

addons: sauce_connect: true

.travis.yml example

Configuring GitHub for Travis

git add .travis.yml

git push origin master

..and commit our changes

Now we add our Travis config file to our GitHub project:

READY TO BUILD!!!
