Is Your Website Cross Browser Friendly?

Wednesday October 23, 2013

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.

What is Cross Browser testing?

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.

  • Simplifying website management and updates
  • Rendering consistent functionality across all the web pages
  • Providing ease of viewing to end users (customers)
  • Increasing the customer conversion ratio

Importance of cross browser testing

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

Which browsers we should test for compatibility?

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.

What to test for Browser Compatibility?

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:

    HTML is the main component of website pages. Hence, HTML is the primary ingredient that should be checked for compatibility.

  • CSS Styles & CSS Validations:

    It’s essential to check CSS Styles and CSS Validation in order to check the compatibility since CSS has moved to CSS3.

  • Sessions & Cookies:

    It is also necessary to check Sessions and Cookies of each website page.

  • JavaScript:

    JavaScript again requires attention since it varies from browser to browser.

  • Text Alignments & Page Layouts:

    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

  • Font Sizes

  • Mouse Hover

  • SSL Certificates

  • Upload File

  • Export File

  • Scroll Bar Appearance

  • Flash Work

  • Page Zoom In/Out

  • Pop Ups

  • Space between various HTML components, etc.
