According to Statista, the share of global website traffic of mobile devices share(excluding tablets) was 52.6% for mobile devices in 2019 for the fourth quarter. This number continues to increase as more and more users chose to access websites through their mobile devices. This is why it is more important to do a responsive test online and ensure that your website renders perfectly on different mobile devices.

Nowadays, we use our mobile devices more than our desktop devices. It’s pretty convenient and with the performance of mobile devices catching up with laptops, it was about time that we would prefer them. After all, isn’t it convenient to binge on your favorite shows online just before you head to sleep or catching up on your newsfeed while you’re on commute to the office on your mobile devices?

This is why as a developer, you need to make sure that your users get seamless experience on your website regardless of the device they are using. Since every mobile device might use a different viewport, you need to make sure that your website looks and perform on mobile devices as well as your desktop website. One way to make sure of this is by ensuring that your website has responsive web design and it renders perfectly on the different mobile devices. In case you’re wondering, what is a responsive web design, you can refer to our article on the topic.

It can be tricky to test on so many different viewports and debug them simultaneously. That’s where LambdaTest comes in, you can test your website for responsiveness on 56+ devices and make sure that your website looks great on all of them! In this article, I’ll highlight 9 important features that will help you to do Responsive testing easily.

1. Switch Monitor Size

With Lambdatest you can pick your monitor size( diagonal length of your screen). This feature was rolled out in order to make sure that the viewport remains with different screen sizes, and there is no discrepancy in checking responsiveness on different screen sizes.

3. Switch To Real-Time On The Same Configuration

This feature was actually requested by one of our users, and it has actually worked like a charm for a lot of users and helped them save their time while easily switching from responsive testing to real-time cross browser testing. A lot of time users would want to move to live sessions from responsive testing. Earlier this process at times proved to be a hassle as users would have to go again with the process of selecting browsers, OS, and their version. With this simple but effective feature, users can easily switch to live testing sessions on the same configuration

This was one of many times our users have helped us to improve. For us, at LambdaTest our users are really important and any such suggestions are always welcome and we’d love to go the extra mile for you guys.

5. Enable Smart Scroll

In certain cases, your pages might have some iframes and they have scrolls. What happens when we perform responsive testing then? Well, in such cases you’d have to scroll through every iframe, and scrolling through each one can prove to be such a hassle. So, how do you fix it? This issue can be easily fixed by turning on the smart scroll. This would ignore any scroll in the iframe and you wouldn’t have to spend eternity just scrolling down the page.
