9 reasons why responsive testing is important?

Many experts consider HTML to be a very progressive style of web development. HTML can expand data and holders both vertically and horizontally to use all given areas. However, because of the fluid mechanics of HTML Framework, it becomes very complex to create complicated web-based designs. To cope up with this issue, many websites adopted a definite-width-based design for all popular device dimensions. The Screen dimension evolution process was not affected by this adaptation of specific width. For example, the evolution of standard device resolution density started to move from 800×600 to 1024×768. However, this calculation was vastly affected by the advancement of mobile phones and the release of the Apple iPhone in 2007. In the modern generation, almost 50% of the total population uses the smartphone to visit the internet.

From a technical point of view, smartphones usually have higher resolution compared to most displays or home desktops. For instance, an iPhone 12 Pro Max reduces its original brightness of 1028×768 to an acceptable 896×414. This acceptable pixel density can create a 3×3 grid structure. The primary goal of this process is to provide a smooth experience and high-quality images on almost all smartphones. In the starting years of web development, companies had to invest in a separate website for mobile and desktop platforms. They also implemented features such as the sniffing of the user widget for providing smooth redirecting ability. However, this momentary approach soon lost practicality due to the variations of devices that started to come into the mobile industry. 

The companies began to look desperately for new ways to meet the new browsing requirements. At last, responsive web designing technology was born in the year 2010. This Revolutionary Technology allowed developers to use the same website on different smart gadgets despite viewport dimensions or screen size variations. 

Here is an amazing article that talks about why responsive design web design is important.

The Functioning Mechanism for Responsive Web Design

Before understanding the functioning basics for RWD, we must realize that there isn’t a singular solution of RWD for implementing Technology. Firstly, developers have to analyze how the website would react to different screen sizes. This is often considered the greatest challenge of implementing RWD. The crude form of this approach was to take a present desktop web layout and start removing elements as the screen size begins to decrease. A more refined way to deal with this issue was to use “the mobile-first principle.” The basic idea of this principle is to consider the linear smartphone view that functions on almost all available mobile devices. Then, the application will slowly begin to add more elements as more space and browsers become available.


With the advancement of technology, many websites have changed into simple Layout to keep a similar experience for both mobile and desktop platforms. To analyze the functional mechanism of responsive web design we can use the example of a hotdog menu.  Using this menu, people with a limited screen can click on the icon to view the menu link. On the other hand, people on wider screens will have the opportunity to view the complete horizontal menu list. This is an excellent example to justify the capacitive mechanism of responsive web design Techniques. 

The Importance of Responsive Testing

We already discussed that responsive web design is a complex form of web development Technology. So, the developers have to ensure that it is working properly before releasing the product. Therefore, the testing phase plays a vital role in the responsive web designing process. There are various elements such as tool selection, phase division, and time analysis that helps in the smooth execution of the testing phase.  Now, let’s take a look at some of the reasons that justify the importance of responsive testing

1.An HTML Meta Tag for RWD

Modern web developers often have a misbelief that responsive web designing completely abolishes the primitive web designing Technology. However, there are certain compulsory factors that a web developer must have in a responsive web design. For instance, the developers have to specify the viewport dimension in the HTML header of the web design. Using these specifications, the mobile browser can increase all the elements of the webpage depending on the available space. So, the developers must perform responsive testing to ensure all the elements are working properly. In case this meta tag is absent, the browsers will consider that it is rendering a computer website. 

2.Meta Queries for Web Designing

All responsive web designing Technologies have their initial base set down on media queries. All Media queries help with CSS ports to target certain ports to increase the viewing experience of the end-users. Even with the advancement of Technology, many media queries are present on almost all major responsive websites.  So, we can easily justify the proper functioning of these media queries play a vital role in ensuring the stable performance of the website. However, presently developers can either include them in the main framework or avoid them altogether according to their desire. 

3.The Layout of Child Element with CSS Flexbox and Grid

Web developers can use CSS flex board and grid to lay all the child elements on the website. Developers can make calculations depending on the available space in the screen size. Flex boards and Grids work on the same mechanism but have some primary differences. For instance, a flex board helps to create one-dimensional layouts whereas a Grid lays the foundation for a two-dimensional responsive web layout. Using this function, a developer can also add similar rows and columns to the web application. So, companies must properly assess these elements before the final release. 

4.RWD Options for Java Script

The advancement of technology has enabled developers to use JavaScript for determining viewport dimensions and act properly. Alternatively, developers can also use JavaScript to study the dimensions of individual elements with the help of offsetWidth along with offsetHeight parameters. This contributes largely towards determining the proper functioning of all the visual elements present in a responsive website. Companies must utilize the full potential of JavaScript during the testing life cycle of a responsive web application. This will help them to ensure that the website remains interactive irrespective of the screen limitation.  

5.Support for Almost All Browsers

Support for Browers is one of the important factors that ensure your website is accessible to a range of audiences. A recent survey suggests that most of the total internet traffic is dominated by the Google Chrome browser. However, this doesn’t mean that developer will ignore the proper functioning of the application on certain browsers like Internet Explorer or Opera Mini. This is because, in this competitive industry, a company cannot afford to alienate any segment of the audience based on device incompatibility. So, the developer must pay proper attention to browser support during the responsive testing process.

6.Testing Within the Browser

Resizing the mobile browser window for responsive testing was used as one of the most acceptable approaches for a few years.  However, over time, this strategy became inaccurate and tiresome. The Latest browsers have a responsive user menu that allows the testing of RWD applications. This mode allows the developers to have a lot of customizations to increase the accuracy of the testing process. During this process, the developers must remember that every browser has its different way of this system mechanism and a separate list of commands. They must perform thorough research on all of these requirements before implementing this process.

7.Emulators for Creating a Mobile OS Environment

With the modernization of technology, companies no longer have to maintain new devices to perform their testing processes. Instead, they can easily run a virtual Android or Apple machine on their native desktop. With the help of these emulators, the developers can download and execute real mobile browsers and utilize the full potential of original rendering engines.  It is one of the easiest ways to ensure the working mechanism of responsive websites on various mobile browsers. This process also helps in the timely delivery of high-quality applications to the end-users. 

8.Various Online Responsive Web Testing Tools and Platforms

In the present generation, various online services allow testers to perform responsive testing on the internet. In this process, the developers have to rent a specific time on a normal device and view their application on the tester’s Browser. The main benefit of this process is that the developers do not have to establish a physical testing environment or test lab of various expensive devices. The ability to run automatic responsive testing is one of the normal services given by these online testing services. Let us consider the example of an online testing tool to understand this concept:

LT browser is a tool to perform responsive web testing on an automated cloud environment. Using this tool, the developers can test the responsiveness of the website on more than 25 real devices simultaneously. LT browser also allows the testers to test the website on the browser itself. To use this function, the developer can use the free Chrome extension available in the Chrome extension Store. This tool can also test the responsiveness of locally hosted web pages. Lastly, the LT browser allows the developers to test the variation of all visual elements depending on the screen size and device resolution.

9.Testing on Real Devices

It is a universal truth that nothing can eliminate the importance of testing your web application on real smartphones. It is the most accurate way to receive vital analytical data such as speed of access, adaptive touch detection, and responsiveness of your web design. From a theoretical point of view, the developers must test the application on as many real smartphones as possible. Many experts advise that developers must never consider their device as a parameter for responsive testing. This is because a recent survey suggests that more than half of internet traffic uses mobile devices that are almost 2 years old. All these factors will play a vital role in ensuring that the web application is functional on all mobile and desktop devices. 

The Conclusive Opinions

The primary goal of responsive web designing Technologies is to enable companies to develop one web application that can be accessed by any user on any mobile or browser. These web applications are not dependent on any form of technical barriers or device boundaries. A critical thing that every developer must remember is that developing a responsive application and transforming it into customer-friendly is completely different. It is a good idea for a company to have dedicated teams for both of these tasks. Lastly, we would like to say that the tool selection process plays a vital role in ensuring the success of responsive testing. During this process, the testers must consider the company ideas and project requirements to make a perfect choice.
