Come explore how you can create a full Continuous Integration solution entirely in the Cloud using GitHub, Selenium, Sauce Labs, and Travis CI. We'll show you how you can take advantage of these hosted development resources to improve the velocity of your releases and increase application quality demanded by your users.
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 Process 1. 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:
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:[email protected]: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 --add travis 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:
