But, considering the wide variety of mobile phones, testing your website on each device manually is not an ideal approach. Also, smartphones come with varied screen sizes, viewports, pixel densities, and operate on varying network speeds. Thus, you need to ensure that the website is tested thoroughly to cover all these differences and meet the desired output. So, what could be done to achieve maximum results for your mobile website testing?

Let’s dive into the top 5 ways to do it-

1. LT Browser For Responsive Testing

  • Allows comparing the mobile view of websites across different mobiles and tablets with a side-by-side view so that you can ensure complete responsiveness.

2. Use iOS & Android Emulator

Software emulators are still one of the simplest ways to test the mobile view of the website. Emulators allow you to run the same software and applications of the original device without altering them, as well as it shows the difference between duplicate systems.

Looking to perform Android and iOS app testing on Real Device Cloud, check out our video below –

Although iOS and Android emulators are specially designed for testing native apps, they can also be used to test the mobile version of your site in the default browsers. This will provide you with a reasonable estimate of how your website renders across the in-built browsers. The rendering engine can also help you find the compatibility or cross-browser issues for your site.

iOS simulator comes as an in-built utility with Xcode, which can be downloaded from the Mac App Store. To access the simulator, follow the below steps:

  • First of all, download Xcode from the Mac App store
  • In the Xcode menu, select Xcode and click Open Developer tool, and then choose iOS Simulator.

Xcode is only included with Mac operating systems, which means your web app can only be tested for iOS devices. To test your website for Windows apps, you can use Windows Phone Emulator, which comes with full-blown SDK, multiple screen resolutions, screenshot tools, etc.

For Android devices, you can download an Android Studio emulator that allows you to create a virtual mobile device for testing android applications and test mobile websites. Android Studio emulator comes integrated with the Android SDK package and works flawlessly across Windows, Mac, OS, and Linux OS. Test your websites on an online APK Emulator.

3. Use Browser Tool – Responsinator

If you want to perform responsive testing of your web app across various screen resolutions, then you can use the browser tools like Responsinator. It is absolutely free of cost and works great in terms of testing the layout of your web app.

Responsinator enables you to resize your website to a specific size so that you can analyze how it will look across multiple devices on various screen sizes. To use the Responsinator tool, follow the below steps:

  • Visit the official site of Responsinator
  • Type the website URL in the given field and click Go.
  • It will start generating live previews for the website according to the resolution of popular devices.

Using Responsinator is an ideal method to perform a sanity check on your website. But, it is not as good as testing your site on real devices or using a simulator, as it uses the same rendering engine as the mobile browser.

4. Test On Real Devices

The ideal approach for mobile website testing is to test it on real devices because there are many instances of a web app that cannot be tested with emulators or developer tools. For example, the user experience on a website contains many factors like pixel densities, varied network conditions, real page loading speed and time, and much more. And all these factors can be tested efficiently on real devices.

Of course, it is not easy to test a web app across each device manually, as it requires investment, resources, and time. Instead, you can opt for a mobile device test suite that consists of the most popular mobile web browsers like Chrome, Safari, Opera, Mozilla, etc. It will help you test your site under real-world conditions and provide you with accurate results that you’re looking for.

However, if you’re not okay with a mobile device test suite, then you can opt for an automated mobile testing tool, which is specifically designed to test a web app across multiple smartphones and browsers.

Here is a quick video tutorial on the real-time browser testing on Real Devices.

5. Validate The HTML and CSS Code

To analyze the functionality of a web app across all platforms, it is recommended to validate your website’s HTML and CSS code. Now, to validate your HTML, CSS, you can take help from open-source tools like W3C MobileOK Checker. It is a web-based automated validation tool that enables you to test the compatibility of your site across mobile devices. It provides you with several test scenarios that verify the user-friendliness of your website.

Another option is the Google Chrome Developer Tool, which allows you to fix minor issues with the HTML and CSS of your site. Using this utility, you can quickly test the behavior of your website across various screen sizes, load times, and network throttling.
