Frequently Asked Questions

Simply put, a mobile-friendly test helps QAs evaluate how a website renders and operates on mobile devices and browsers. This is exceptionally important, as the following numbers will prove:

  1. 85% of adults think that a company’s website when viewed on a mobile device should be as good or better than its desktop website. (Source)
  2. As of Q2 2018, smartphones held a 63% share of all retail website visits. (Source)
  3. 83% of mobile users say that a seamless experience across all devices is very important. (Source)

Running comprehensive mobile friendly tests is essential to make a website user friendly, and to keep people coming back, and keep traffic and revenue at desirable levels. Users do not take mobile-incompatible websites seriously in a world with smartphones in every palm.

There are two ways for devs and QAs to test their websites for mobile device compatibility

  1. They can use an in-house device lab with hundreds of real mobile devices. Putting together, maintaining, and updating such a lab would take significant financial investment and sustained human effort and time. Needless to say, this isn’t a feasible option for individual devs, QAs, or even small-scale organizations without a monetary warchest to back them up.
  2. In the absence of a device lab, QAs can use a mobile friendly website tester like BrowserStack. They don’t have to worry about buying devices or maintaining them. They can simply sign up, access a real device cloud, and test their website on a multitude of mobile devices, including the latest devices.

Now, developers and QAs do tend to use emulators and simulators to test their websites. However, these tools are fairly unreliable as they cannot replicate real user conditions in their entirety. That means any tests run on them will not return accurate results, and bugs are highly likely to escape into production without being detected during the QA phase.

There are multiple tactics to make a website mobile-friendly and keep mobile users happy. Instead of one line pointers, check out our article on how to ensure mobile website compatibility.

Once these steps have been implemented, the site has to be tested on real mobile devices to ensure that the steps have actually made it mobile compatible. This is where the mobile friendly website tester comes in. 

Once website development has started, and a minimum viable product is ready, QAs can test it on a mobile friendly website tester to check how it stands up to the specifications of different mobile devices.

It is best to start testing as early as possible. Bugs tend to magnify if they are left undetected. The earlier they are detected, the easier they are to resolve. Testing at later stages will cause QAs to face a large number of complicated errors and incompatibilities, which will take far more time to untangle and fix.

As mentioned before, the mobile device compatibility of a website is of utmost importance. Once development is underway, it can be monitored on a mobile-friendly website tester to check how it works with mobile devices.

Devs and QAs can test their sites on BrowserStack for this purpose. With 3000+ real browsers and devices on our real device cloud, they can verify website performance on hundreds of real mobile devices, installed with real mobile browsers and operating systems. They can test on multiple versions of mobile browsers, running on devices from different manufacturers, especially the latest ones.  

As mentioned, BrowserStack offers a real device cloud of 3000+ real browsers and devices. So, all QAs have to do is to sign up for free, select the mobile device-browser-OS combination they require, and start testing.

They can run manual tests on real mobile devices via BrowserStack Live. Automated website tests are also easy to run via BrowserStack Automate. Run automated Selenium testing on a Cloud Selenum Grid with 99.9% uptime. They can test faster with parallel testing, thus saving time and minimizing effort without compromising on accuracy in the slightest.

Essentially, a mobile friendly website tester can be used to verify if a website is compatible with mobile versions of internet browsers. For example, let’s say a website needs to be checked for compatibility with mobile versions of Chrome, Opera, Firefox, and Safari.

Instead of downloading each browser separately to run tests, QAs can simply access a mobile friendly website tester. It lets them check website compatibility on multiple mobile browsers without downloading any of them.

A mobile friendly website tester will also check a website’s responsive design with multiple mobile devices – each with different screen sizes and resolutions.
