<What is Cross Browser Automation Testing & How to perform it?>

Cross-browser testing is a technique that is used to test the behaviour of a website or an application in multiple browsers. It is necessary to ensure that your web application or website is performing accurately on all the browsers due to the fact that browsers have a different method of presenting the site, in which case differences and errors might occur in the layout, feature or functionality. It involves examining the compatibility of your application across multiple web browsers. Cross-Browser testing involves testing both the client-side and server-side behaviour of the Web application when it is accessed using different Web Browsers.

With the availability of a wide range of web browsers, the end-users are using a variety of web browsers to access the web applications. Web-based applications are totally different from Windows applications. A web application can be opened in any browser by the end-user. Thus, it has now become crucial to test web applications on multiple browsers. The client components like JavaScript, AJAX requests, Applets, Flash, Flex, etc. may behave differently on different browsers. Also, the process of request handling for different browsers also varies.

How to Automate Cross Browser Testing?

i) With the help of Selenium WebDriver, we can automate test cases and run those test cases simultaneously across various browsers such as Internet Explorer, Firefox, Chrome, and Safari browsers.

ii) TestNG framework with Selenium WebDriver is used for the execution of the same test cases on the same machine at the same time but with different browsers.

Selenium WebDriver can be used to run browser compatibility tests on various browsers such as Chrome, Firefox, Internet Explorer, Safari, and Opera. WebDriver API drives the web browser just like a real user. Firefox Driver has a ‘selenium-server-standalone.jar’ library by default while Chrome, IE, Safari, and Opera do need external libraries. In order to perform cross-browser automation testing, one needs to initialize WebDriver for various browsers. Let us discuss various browsers and also the steps to initialize WebDriver for different browsers.

1. Mozilla Firefox: The ‘selenium-server-standalone’ library is bundled with Firefox Driver to initialize and run tests in a Firefox browser. Firefox Driver is added to the Firefox profile as a file extension on starting a new instance of Firefox Driver. To start Mozilla Firefox, the code is:

WebDriver driver = new FirefoxDriver();

2. Google Chrome: Chrome Driver is an external library file that makes use of WebDriver protocol to run Selenium tests in a Google Chrome web browser. To start Google Chrome, the code is:

System.setProperty("webdriver.chrome.driver","C:\\chromedriver.exe");

WebDriver driver = new ChromeDriver();

3. Internet Explorer: IEDriverServer is an executable file. It uses the WebDriver wire protocol to control the IE browser in Windows. IE versions ranging from 6 up to 10 are supported by it. To start Internet Explorer, the code is:

System.setProperty("webdriver.ie.driver","C:\\IEDriverServer.exe");

DesiredCapabilities dc = DesiredCapabilities.internetExplorer();

dc.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true);

WebDriver driver = new InternetExplorerDriver(dc);

4. Apple Safari: Just like FirefoxDriver, SafariDriver is also internally bundled with the latest Selenium servers thereby starting the Apple Safari browser without any external library. SafariDriver supports the Safari browser version 5.1.x and runs only on MAC. To initiate SafariDriver, the code is:

WebDriver driver = new SafariDriver();

5. Opera: OperaPrestoDriver (formerly called OperaDriver) is available only for Presto-based Opera browsers. Currently, it does not support Opera versions 12.x and above. However, the recent releases (Opera 15.x and above) of Blink-based Opera browsers are handled using OperaChromiumDriver. To initiate OperaChromiumDriver, the code is:

DesiredCapabilities capabilities = new DesiredCapabilities();

capabilities.setCapability("opera.binary", "C://Program Files (x86)//Opera//opera.exe");

capabilities.setCapability("opera.log.level", "CONFIG");

WebDriver driver = new OperaDriver(capabilities);

Advantages of Cross Browser Automation Testing

i) Automation of different types of browsers can be achieved by using Selenium.

ii) Multi-Browser Testing can be performed by integrating Selenium with TestNG.

iii) Test scripts are reusable and can be used across various environments, parameters, and scenarios.

iv) Automated testing offers a level of consistency that is not achievable by using manual testing.

"I really appreciate the effort you made to share this knowledge, I also want to mention 5 benefits of Automated Cross Browser Testing - 1. Scalability and flexibility is the key to successful cross-browser testing. 2. Higher test coverage - One of the greatest challenges with cross-browser testing is to test across the combinations of several browsers, os, and devices. This combination gives rise to a large number of devices to be tested together. 3. More accurate test results - It is difficult to achieve efficiency in cross-browser testing done manually. 4. Simultaneous execution of test cases will enable the test to run faster 5. Save time and Money - With cross-browser automation testing, we are able to find the bugs from the earlier stages, otherwise, in the later stages, it is difficult to detect and report bugs. <a href=""https://softwaretestingboard.com/subscribe/#axzz6k6hRhJhO"">Subscribe to our page for more information</a>"
