When a web or cloud-based application is released, the foremost thing that bothers the developing company is its compatibility across various browsers. A slight lag in the look or working of application on any browser diminishes the months and years of hard work and lowers the company’s reputation.
With a growing number of browsers, it’s imperative that your application kicks off with all these browsers via browser testing. This is the reason, experts have diagnosed and prescribed the need of cross browser testing.
In this article, we will discuss about the nuance of cross browser testing and conduct a comprehensive analysis of its usage with some example tools.
Cross browser testing is a process of testing web applications across multiple browser. Ideally, it is the testing of website, web application, HTML file or client-side scripting to support all the web-browsers. Cross browser testing is generally adopted to ensure that a website or web application works properly on different browsers. It involves compatibility check and testing of both client-side as well as server-side applications.
With the increase in access of website and web application across smartphones, tablets, laptops and iPads which works on different browsers, (e.g. iPad and Mac devices use Safari while Android tablets and smartphones either use Firefox or Chrome) cross browser testing becomes inevitable in order to present unified user experience and functionality to the viewers. Besides, cross browser testing benefits in several aspects such as
There are several browsers that are used by users, however the highly used browsers across the world by people include Google Chrome, Firefox, Internet Explorer, Safari and Opera.
Below are the Browser Usage Statistics (till July 2013) across the world according to one of the surveys which indicate the most preferable browsers for your web application and website testing.
This question concerns almost half of the testers. For checking whether the application works the way it should across all the browsers, you should take a look at the following ingredients of a web application or website:
HTML is the main component of website pages. Hence, HTML is the primary ingredient that should be checked for compatibility.
It’s essential to check CSS Styles and CSS Validation in order to check the compatibility since CSS has moved to CSS3.
It is also necessary to check Sessions and Cookies of each website page.
While testing cross-browser compatibility of web apps, you must also check the dropdown, checklists, radio buttons and front-end UI for each browser as they may not be similarly aligned in all the browsers.
Over and above these, there are several other important areas of web applications to be considered for achieving 100% cross-browser compatibility such as
Scroll Bar Appearance
Page Zoom In/Out
Space between various HTML components, etc.
When you are unaware of what browser the users are using when they have a wide choice of utilizing browsers for running your application, checking your application on each of these browsers can turn out to be a big headache leaving you vulnerable. But thanks to some automation tools that are specifically designed to test the application performance and working with different browsers and minimize the testing efforts. These tools can be easily availed depending upon the needs and budget. Check out the comparison of Top 10 Cross Browser Testing Tools.
Here’s a list of some of the leading tools that support cross browser testing:
This is the oldest and the best known free cross-browser testing solution. Though it is available online for free, its response is quite slow. This is the biggest disadvantage of BrowserShots.
This is a commercial service with an appealing interface. However, this tool also lags behind in response time. It has a very nice feature of capturing mobile device which supports Blackberry, iPhone, Android and Windows Mobile devices.
Another web-based service with an impressive browser support of 23 browser versions. It does not support scrolling and captures only the top of the web page, which is a major drawback.
Selenium is a highly popular tool for testing web applications for cross-browser compatibility. It comes with record/playback feature.
This is again an online tool that lets you test your web application across different browsers. The best part is, this tool presents comparison views displaying screenshots of web pages on different browsers for better analysis.
It is a codeless test automation tool supporting cross browser testing. All you need is to select the browsers listed from the drop-down list as shown in the image. It also provides record/playback feature. Moreover, being codeless, this tool can be used even by a layman.
When it’s time to turn your website or web application to something completely functional from mock-ups, make sure it works great on every browser using any of the above mentioned tools.
