  • Responsive Testing: With Examples and Best Practices


Responsive website testing ensures that users have the best experience with your site, regardless of their device. The goal of testing responsive websites is to ensure a seamless experience across different digital devices. In this day and age, we live in a world where technology has enabled convenience, and we are now dependent on our devices to function.

Because of the growing market for mobile devices, businesses are developing strategies to create user-friendly websites. They use mobile-first design, progressive web apps, single-page applications, and more. However, for a unified user experience across devices and platforms, we need to consider screen resolutions and device capabilities.

To create highly responsive websites, you must understand the importance of testing your websites' responsiveness and develop a strategy to implement website responsive testing. This guide will teach you how to create responsive websites, and understand their significance, best practices, and more.


What is Responsive Testing?

Responsive website testing is a process that ensures your website works well on multiple devices by using CSS media queries based on the user's device where the website is accessed.

In simpler terms, responsive testing is a process that enables you to check how well a website works on various types of devices, including desktops and smartphones. A website that responds well to all screen sizes and resolutions gives your business a competitive edge over other companies.

Responsive design incorporates many elements, including media queries, flexible grids, and responsive typography. It makes it easy to build websites that adjust automatically to any screen size. While a responsive design may seem simple, incorporating it into ongoing projects is tricky; it's best to follow its principles before starting a new project.

Website responsive testing is part of the final stage of responsive web design testing. It can be performed using the same toolset as cross-browser testing, which is responsible for improving a website's UI/UX. Responsive testing ensures that your website is not only cross-browser compatible but also adjusts to screen resolution changes.


What is Responsive Design?

Responsive design aims to create websites and web applications that provide an optimal viewing experience across a wide range of devices and screen sizes. A site that is designed responsively will adjust its layout and content to fit the specific device and screen size on which it is being viewed, providing an easy-to-use and seamless experience for the user.

To create a responsive design, designers and developers use a combination of HTML, CSS, and JavaScript. Responsive design often involves using flexible layouts, grids, and images and using media queries in CSS to apply different styles based on the screen size.

Why is Responsive Website Testing Important?

Responsive testing of web apps is crucial at every stage of development to ensure that the end-user requirements are met. Here are the following reasons highlighting the importance to test responsive websites:

  • Plethora of Devices, OS & Browsers: To ensure that your site's content is available to all visitors, verification of the content needs to be done for different screen-sized mobiles, operating systems, and browsers. While a site designed in one browser may appear as intended in another browser, it should not be assumed that this is necessarily the case.
  • Need for Robustness: It is crucial to ensure that the website is loading at the same speed on different devices and browsers so that users do not become frustrated by lagging or timed-out content. If a website loads slowly or doesn't display correctly on mobile devices, users will have a poor experience. Therefore, testing a website's performance is essential for ensuring users have a positive experience on mobile-responsive websites.
  • Website Navigation: When testing a mobile website, one of the most common defects found is that pages don't load as expected when navigated among the site's links. It also happens that links are missing, images are not loaded, or timed out while playing with navigation.
  • Multiple Images and Videos: When creating a responsive website, it is essential to test whether all types of images and videos are displayed as expected on different phones, browsers, etc. Sometimes some videos play well on Android, but they don’t even load on iOS, or some images appear broken on some versions of a mobile operating system while they are perfect on others. Such issues will give a terrible impression if testing is not done correctly.

Advantages of Responsive Website Testing

Responsive web test is an integral part while delivering high-quality products. There are several advantages to performing website responsive testing:

  • Improved User Experience: It is important to ensure that a website is fully responsive to ensure that all users, regardless of their device, have a positive and seamless experience when interacting with the website.
  • Increased Accessibility: A responsive website can be accessed and used by a broader range of devices and screen sizes, which can help to expand its reach and accessibility.
  • Enhanced Search Engine Optimization: Google's search algorithms give higher rankings to mobile-friendly websites, so having a responsive website can help to improve a website's search engine ranking.
  • Cost Saving: Developing and maintaining a separate mobile website can be time-consuming and costly. A responsive website can save time and money by eliminating the need to create and maintain a different mobile version.
  • Improved Conversion Rates: A responsive website can improve conversion rates by providing a consistent user experience across all devices, which helps to build trust and credibility with users.

Types of Responsive Website Testing

There are several types of responsiveness testing types that can be performed to ensure that a website is responsive and functions correctly on a variety of devices and screen sizes:

  • Visual Regression Testing Visual regression testing is a part of regression testing that involves taking screenshots of a website on different devices and comparing them to ensure that the layout and design are consistent across all screens.
  • Visual Layout Testing: Visual layout testing tools allow users to check that the website's layout adjusts correctly to different screen sizes and orientations and that all content is displayed correctly and is easily readable and navigable.
  • Cross browser testing: Cross browser compatibility testing is the most significant kind of front end testing. Testers can determine if a website functions as intended when viewed using various browsers/devices/OS combinations. In addition, cross browser testing makes it possible for people to experience the same thing across multiple browsers.
  • Functional Testing: This involves testing the website's functionality on different devices to ensure that all features and interactions work as expected. Functional testing evaluates the various functions of the application. It checks the user interface, database, APIs, client/server communication, security, and other components.
  • Performance Testing: Performance testing assesses a product's quality and capability under varying workloads. Performance testing ensures that the system performs adequately, reliably, and with stability. This involves testing the website's performance on different devices and networks to ensure that it loads quickly and runs smoothly.
  • Usability Testing: Usability testing is a technique for evaluating the user experience of a web product or service by testing it with users. This involves testing the website's usability on different devices to ensure it is easy for users to navigate and use.

Common Use Cases of Website Responsive Testing

Website responsive testing is a type of testing performed to ensure that a website or application is fully functional and provides a good user experience on a wide range of devices, including desktop computers, laptops, tablets, and smartphones. Here are some common use cases for responsive website testing:

  • Verifying that a website or application is easy to use and navigate on devices with different screen sizes and resolutions.
  • Ensuring that the layout of a website or application is visually appealing and easy to read on all devices.
  • Testing all features and functionality of a website or application is fully operational on all devices.
