Testing Responsive Web Design


In today’s age, the use of mobile devices to access the internet has grown and become quite popular. Almost every internet user desires a mobile version of the website. Most of us, though, don’t have the budget to get hold of the hundreds of physical devices you’d need to carry out a real-world test. These tools provide a halfway house by letting you test your responsive designs within a virtual environment. Every modern web designer should know the principles of responsive web design – how to get your sites to render perfectly on whatever device or screen size it appears on. (If you need a refresher, check out our pro’s guide to responsive web design).


It has up to 9 versions of laptops – from 8-inches to 10-inches screens, 9 smartphones and even 3 extensions from real TVs and of course random size which can be set as you wish. And with the help of just one key, you can quickly share the results of the test with your friends.



Browser Stack is one of the most advanced, full-featured testing tools around. If you’re a Divi users, you’ve already got a suite of practical tools to help you design responsively. Nevertheless, it’s always a good idea to check on the most viewports possible. Your best bet is to have one responsive web design testing window with the Divi Builder and another with a responsive tool that you can refresh regularly. Both responsive and adaptive design are alike in allowing sites to be adapted to mobile devices and various screen extensions, ultimately providing mobile device users with better capabilities.


With users including Twitter, Microsoft, AirBnB and Mastercard, it's obviously doing something right. Verify whether the images of different types like .jpg, .png, .gif, etc are shown as expected. Verify whether the content fits on the screen and is not cut out or distorted. Testing needs to be correctly prioritized because there’s a lot to test and not everything can be tested. Hence the whole team should agree on the testing plan and its priority. The testing priority should be communicated to the BA and the product owner well in advance so that if they have any suggestions, then those can also be looked at. A tool clicking on a small link is very different from clicking with our fingers or manually zooming out a web page rather than a tool zooming out the page.


Essential Web Design Books


This is handy if you like quickly switching back and forth between various device previews. Images in Bootstrap can be scaled to the parent element using the img-fluid class. Screen-specific images can be rendered using the picture HTML element. In this case, the browser will use the stylesheet.css file only if the screen and device widths are lower than or equal to 640 pixels.


  • Therefore, websites should be tested as soon as possible on mobile devices online.
  • The following image shows how LambdaTest changes the navigation bar according to the size.
  • However, emulators are held back by multiple limitations, which prevents any tests run on them from offering conclusive results.
  • Developers will sometimes use one layout for all smartphones, but that can be costly.

The first and foremost step in responsive design testing is to perform cross browser testing on the device and verify if the website is cross browser compatible or not. Cross browser compatibility testing allows you to view and explore your website on any browser, operating system, or resolution.


Test Fonts On Multiple Devices


We should also mention such thing as “Trueview” variation which allows you to look at displaying the website in the native browser of the mobile device . You can use on the platform up to 14 mobile phones and 12 various laptops in order to completely study the layout. Such method can be certainly used but only for immediate visual analysis of site’s functionality in different extensions. This will help to immediately find basic issues with the displaying of the image when we, in our turn, decrease or increase the size of the window of our browser. We understand the critical importance of testing and enforce multiple techniques to ensure our software is fault-free and operates smoothly for our customers.


Responsive Web Design Testing

Browser Stack’s biggest rival in the testing space is CrossBrowserTesting, which offers more than 1,500 browsers and devices to test your responsive website on. Brilliantly, you can then interact with your page, clicking on links, typing into search fields and so on. Note that these Programmer are generic devices, though, not specific ones. Just type in your web page's URL and this free, browser-based tool shows you how your web page renders in the most popular screen shapes and sizes. It is a configurable tool and can be used to customize the screen size of a browser.


Evaluate Your Devices And Browsers Regularly


Accessibility testing is not just a “nice to have” requirement. It is a compliance requirement that needs to be well tested and addressed for both mobile and desktop web. @Samuel – yes, you can automate few test cases of responsive testing. If the browser is resized for testing then any click area (like buttons, menus, sub-links, etc.) of the RW should be suitable for clicking. While testing an RW you should mindful of the design consistency such as the alignment of images, texts, padding around the edges, etc. across all the browsers and Operating systems.


The web version can be easily tested in various browsers and the mobile version on different mobile devices and operating systems – iOS and Android. Breakpoint defines in what way the content and design will be adapted to provide an excellent user experience. Usually, breakpoint marks the disharmony between content and screen resolution. The number of breaking points depends on the number of devices and their screen sizes to monitor if it provides responsiveness.



If you ran a Selenium test to click on different links and buttons on a page, the test would say everything works. Developers will sometimes use one layout for all smartphones, but that can be costly.


Test For User Conditions


There are several tools available to test the responsiveness of a mobile – both free and paid ones. Gone are the days when we used to sit in front of our desktops or laptops to do shopping or internet surfing or emailing. Now it’s the mobile era and people access the internet while walking on the streets, sitting in a park, and anywhere they wish according to their comfort. This tool is for everyone who needs a quick and easy way to test their website design in multiple screen widths. We chose the tools on this list because they are all practical and easy to use. Some are better than others and the one you need depends on how complex your design is.


Responsive Web Design Testing

It is impossible to say what way is the best for use as both of them have their pros and cons, as they suit different websites and industries. However, device resolution is crucial to consider as you can not predict what device your visitors will use to surf the website. To make the crucial duty of testing your site’s responsiveness easier, here are a few excellent free online tools to check out. This post covers the evolution of responsive design, the basic components that make it work, and a guide to creating and testing responsive web applications.


What Is Responsive Design?


To begin with, we would like to define what responsive design is. Responsive web design is a design approach that lets you adapt the website content to diverse screen and window sizes like desktop, mobile, and tablet. This approach helps to visualize the screen look on different screens to make it responsive anyway. Responsive design also gives the ability to transform the content according to particular screen sizes. Responsive web design is an approach to websites in which design and development respond to the user’s environment based on screen size and orientation. This eliminates the need for a new design and new set of code for each new device. With responsive design, there’s one set of code that flexibly accommodates the different devices and dimensions your audience uses.



Like Responsinator, this responsive web design testing tool by pixeltuner.de allows you to enter a URL which is then rendered inside several device mockups. Bootstrap provides a starter template, complete with a viewport tag. The basic premise of Bootstrap’s design is a 12 grid layout that a developer can use while defining DOM elements. These columns are available across screen sizes and define relative widths. Responsive design allows developers to write a single set of HTML, CSS, and JavaScript code for multiple devices, platforms, and browsers. Responsive design is device-agnostic and aligns with the popular development philosophy of Don’t Repeat Yourself .


Make sure you always include a srcset that with different sizes of your photo when you add images to your pages. The % unit approximates to a single percentage of the width or height of the viewport and makes sure the image remains in silverlight proportion to the screen. Whether or not WordPress sites are responsive depends on the theme of your WP site. A WordPress themeis the equivalent of a template for a static website and controls the design and layout of your content.


Main Components Of Responsive Website Design:


They lack the hardware modifications that affect the viewport size and therefore the visual correctness of the site. When you're designing your responsive website for a smartphone, always consider the smallest screen size in a size range. If your breakpoints choose Layout A between width of 250 pixels and 450 pixels, be sure to test on the smaller end of the range because images tend to get misaligned on smaller screens. Resizing the browser and testing the responsive website can identify only a few major issues whereas there may be a few other issues related to finger-swipes, tapping, etc. on mobile devices. Testing these particular features on the actual devices can lead to better defect finding and removal. Check whether the web pages are readable at all resolutions, i.e. the content should be readable even if we resize the browser to mobile screen size. To use this feature of chrome, open any testing responsive design website like in chrome and right-click on the webpage and select “Inspect” option from the menu or press Ctrl+Shift+I.


Responsive Checker Tools are essential to ensuring that a website provides the optimal user experience across as many devices as possible. This means taking into account a large variety of Code review screen sizes, device configurations and other factors that have become a major concern due to device fragmentation. Ideally, every website must be verified with a responsive tester tool.


Google Chrome developer tools can provide network HAR file, performance metrics, and other insights. These will help you address these kinds of tests in addition to other load testing solutions. See for example how Perfecto's responsive website looks across different screen size widths. It's critical to validate that the site menus allow for full site navigation and that website features operate across all sizes, platforms, and user conditions. While emulators are good for basic manual testing, they do not mimic the true web user experience on a real smartphone.
