Mobile web testing is an approach engaged by website developers to ensure that the design of a particular website meets the uniformity of all existing designs of various smartphones. 

Further, the testing approach can also be named responsive website testing since it comprises analyzing whether the websites are responsive in different screen resolutions.

There are various benefits of conducting mobile web testing including browser compatibility, OS compatibility, user-friendly design, SEO advantage, and enhanced visibility. 

Moreover, browser compatibility is a major benefit of conducting web testing since it ensures that a website works seamlessly in existing mobile web browsers such as Safari, Brave, and Google Chrome.

Creating a user-friendly design is one of the benefits of conducting mobile web testing since it enhances optimization for websites to ensure that they are user-friendly and can offer driving conversations between users. 

However, mobile web testing leads to enhanced visibility that entices users to enjoy browsing through content shared on a particular website.

Why Do We Need Mobile Web Testing?

Mobile web testing is needed today to ensure that users consuming content using their smartphones enjoy the responsive aspect of a website. 

Therefore, the convenience of using mobile phones for browsing and content interaction purposes has been influenced by the crafting of mobile-friendly user experiences. 

Therefore, developers need to consider creating responsive website designs due to the increasing number of smartphone users since in the future there will be more users who will be accessing various website services and products via mobile. 

There are several reasons why focusing on mobile usability testing is essential when developing a web product:

  • Mobile-first indexing

Mobile-first indexing is amongst the major reasons why mobile web testing is essential since it describes why search engines provide preferences for websites that are responsive to diverse resolutions of different mobile types. 

For instance, if a website does not have a mobile responsive feature, it has minimal chances of appearing in the first few pages of a search engine like Google.

  • Speed and accuracy

Most of the users have turned to using mobile phones rather than using laptops since smartphones are more personal and convenient to use. 

So, developers should engage in testing the responsiveness of a website to suit the resolution of the existing mobile devices since it will satisfy an intended audience.

Automated tests can be done at scale on real devices that you neither own nor manage to evaluate the functionality and performance of your websiteTesting on many browsers, platforms, and actual mobile devices in tandem can speed up the testing process for mobile websites.

  • Exceptional user experience

Designing a good and fast mobile website is essential since it plays a significant role in maintaining consumer loyalty that leads to referrals which enables the entity offering the website service to acquire more users. 

Besides, a good user experience can be determined by the feedback a website gets from its users regarding the efficiency of services and products offered on its website.

  • Mobile device compatibility

Conducting web testing does not necessarily mean testing the functionality of a website on all the mobile phones existing in the market, but it means accessing data based on the various mobile devices used by many people.

After determining the most used devices, the next step that developers should engage in is to test the performance and user experience on the selected devices to identify and fix any existing issues that might make a website not responsive. 

By following these steps, the developers of websites deliver exceptional user experience on different mobile devices that leave the users fully satisfied by interacting with an interactive website design.

How to Perform Mobile Website Testing Effectively?

Firstly, you can’t test your website by using real mobile devices as there are mobile devices with different resolutions and it would be very time-consuming to check metrics this way.

So, for the execution of an appropriate mobile web testing strategy, you need to perform various steps to improve the efficiency of the process.

Before starting the process, you should first consider the product features and mobile devices since it is a priority to understand how the website works on different mobile devices. Below are some of the recommended approaches that can be used to test website on mobile devices: 

  • Validation of HTML and CSS code

One of the most powerful tools used in mobile web testing is W3C mobileOK Checker which is an automated method that is preferred for use by most developers since it does not involve manual testing procedures used to validate HTML and CSS code.

Therefore, W3C mobileOK Checker is an open-source medium that enhances the removal of errors present in HTML and CSS code to ensure that the website meets all the requirements of creating a responsive website.

Since this is one of the most recommended tools when testing for the responsiveness of a website on a mobile device, the tools enhance testing procedures by providing a well-explained report covering failures detected on a website.

  • Chrome Dev Tools


The other validation tool is Chrome Dev Tools since it enhances the checking and fixing of issues detected when testing the HTML and CSS code used to develop a particular website.

Besides, its other advantage is letting the website owners know about core web vitals and also helping testers test for the responsiveness of a website on mobile devices when there is a network issue that might arise due to increased usage of the network by users of mobile devices.

  • Mobile-friendliness testing

When testing for mobile friendliness, CrossBrowserTesting is the best tool for use since it comprises more than 2050 mobile browsers that can be used to test for the responsiveness of a website. 

Through using CrossBrowserTesting, one can easily determine whether a website is hosted locally or publicly to support various browsers by ensuring the website meets the required specifications of different browsers. 

Therefore, CrossBrowserTesting is a one-stop tool that can be used to conduct automated testing to remove bug issues detected in a code to ensure that a website fits the required specifications of existing web browsers.

Several features of CrossBrowserTesting that enhance automated testing include the Selenium-based automated and live website responsive testing. The other feature is Uncompromised security with pristine browsers and devices available on demand. 

All the features mentioned above describe how a website is displayed to enhance responsiveness since developers are required to use responsive design tools to create a website that offers high performance on multiple devices without lag.

  • Using BrowserStack’s responsive checker tool

Numerous device types and browser versions exist on the internet, which are highly fragmented. 

Therefore, as of 2021 and forward, every firm must have a responsive website. Because of this, having an adaptable website design is essential to a company's ability to expand online.

It is free for individuals and groups to use BrowserStack's Responsive Checker to test how their website looks on a variety of devices, including well-known ones like the iPad Pro, iPhone X, and Galaxy Note 10. 

This makes it easier to spot any rendering issues or inconsistent viewing across devices.

It is really easy to utilize this tool. 

Firstly, you need to fill your website in and next, you must click the Check button after entering the target website's URL. After that, the webpage loads on many devices with distinct resolutions.

Further, you can also use mobile emulators and perform cloud storage mobile testing on real devices.

Limitations of Mobile Web Testing

As we now know about how to do mobile web testing and its benefits, it also comes with some disadvantages.

However, web developers can surpass these limitations by taking more care and also using real devices in some instances, and keeping most of the mobile testing through mobile web testing tools. 

  • Limited environment

A limited environment is one of the most commonly experienced limitations when conducting mobile web testing because of the variations existing within different Operating System versions and network conditions that might cause inconvenience during the testing procedure.

  • Performance variations

The performance of different smartphones might cause differences in user experience leading to a lack of accuracy for the emulator trying to execute the mobile web testing procedure. 

  • Dynamic content

Real-time interactions and dynamic content might not be handled by emulators with the same accuracy as by real devices. A consumer would typically become disinterested in returning to a website or web app if the page loads slowly. 

  • Network conditions

Accurately simulating real-world network variability in testing settings is difficult, as slow or unreliable connections can result in varying results regarding the testing procedure engaged by developers.
