How To Perform Mobile Web Browser Testing [2022]

The primary web site was launched in 1991, however nobody may have predicted that these web sites wouldn’t be simply confined to desktops or laptops. Nonetheless, with the emergence of cellular units, individuals most well-liked to view their web sites (or internet pages) on cellular fairly than a laptop computer or a desktop.

As per a survey, greater than 54% of web visitors comes from cellular units. This 50% mark was crossed in 2017 and has been constant sufficient to offer strong proof of how individuals love cellular browser exploration. Due to this fact, it’s grow to be essential to conduct cellular internet browser testing for an ultimate mobile experience.


The ripple impact of this person desire in the direction of mobiles will be seen on cellular producers, browser builders, search engine builders, enterprise strategists, and every thing that is determined by a web site. As cellular screens have minimal house, you want to choose important parts that your customers require probably the most whereas eliminating fluff whereas designing for them. Due to this fact, internet builders are adopting the mobile-first design.

Creating wonderful web sites for desktops and cellular units has grow to be more and more essential for organizations. An additional step in thorough testing is to investigate each varied features and their impression on cellular internet browser testing and methods to do it.

On this information, we focus on the fundamentals and significance of cellular internet browser testing, its completely different approaches, and methods to carry out cellular web site assessments.

What’s a Cellular internet?

A cellular internet or web site, like each web site, is made up of browser-based HTML pages which might be linked collectively and accessible over the online. Nonetheless, the cellular web site is meant for smaller display screen sizes and touch-screen interplay. In such circumstances, responsive web design is shortly turning into the brand new benchmark for mobile-friendly web sites and scales to any measurement display screen — from desktop to pill to smartphone.

Moreover, cellular web sites can present texts, information, photos, and movies. They will additionally embrace mobile-specific capabilities like accessing a telephone quantity or location-based providers.

In the US, the next are probably the most seen cellular internet purposes moreover Google and YouTube.


All of them have a couple of billion web page visits every month. They remodel their purposes as quickly as some new analysis pops up. It may additionally not be flawed to say that individuals nonetheless bounce proper again when the glitches are rectified, even when they one way or the other make a mistake.

Why is Cellular internet browser testing a should?

In response to a survey, a poorly designed web site deters 57% of web customers from recommending a enterprise. One other survey reveals — the primary 50 milliseconds rely to make a superb impression! An opinion will be fashioned inside 50 milliseconds, giving us not more than a blink to maintain the person on the web site. That’s a serious problem, particularly for people, small companies, and startups.

At this time’s extremely fragmented world is without doubt one of the major causes that demand cellular internet browser testing. In response to a survey, world statistics present the Android working system is within the palms of practically 70% of all cellular machine customers.

In case you dig into the Android fragmentation or model distribution, you’ll discover that each one the shoppers (end-users) aren’t on the similar degree. It’s because many customers don’t improve their units so regularly (in the event that they obtain the newest updates).

In response to the next stats, solely 37% use the newest Android model.

It’s not simply Android that’s fragmented; iOS additionally suffers model fragmentation, particularly with the introduction of iPad OS.

Briefly, what we’ve mentioned above isn’t an abrupt flip of occasions however fairly the result of a constant desire in the direction of a single area of units. Cellular machine progress is unparalleled to any of the opposite units. Worldwide information company tasks this constant progress to maneuver additional up with greater than 1.5 billion smartphones delivery in 2025.


Such elements increase a must have a mobile-friendly web site as it can change into the largest supply of your visitors.

Aside from the cellular units and their direct impression on enterprise, being seen in engines like google is one other main issue for conducting cellular web site assessments.

In 2017, Google introduced mobile-first indexing to the general public. This was not a separate index, however Google prioritized mobile-friendly web sites. Finally, it improves the shopping expertise for guests.

An internet site that isn’t mobile-friendly, particularly one which hasn’t been examined for cellular internet, gained’t be prioritized and can, consequently, seem on the backside of the outcomes. So in case you are simply beginning, this might pose an irreversible danger to your online business.

Focus areas for Cellular internet browser testing

Cellular internet browser testing requires an intensive evaluation of many segments that may have an effect on the ultimate render on the display screen. The next areas are typically below focus throughout cellular web site assessments for anomalies.

Display measurement

To satiate completely different customers’ requests, producers intention at offering cellular units with completely different display screen sizes in the identical mannequin. It has been a superb technique to extend gross sales and canopy a bigger viewers. Though it may be thought-about a major step in cellular internet testing, it’s not a serious concern for the testers. Cellular units typically are available predefined display screen sizes from all of the producers. This helps the producers create a reference level for his or her subsequent buy.

Nonetheless, we can also think about tablets and different units that fall between tablets and desktops, comparable to Microsoft’s Floor Professional. However you’ll be able to simply cowl the great checklist for testing shortly.


The following section to check is the decision of the machine. It’s typically proven within the format as X . The higher decision a tool has, the extra refined its display screen is and in the end a greater expertise for the person.

Probably the most extreme impact of an internet web page on the decision is when builders outline absolute numbers for his or her parts.

For instance, defining the width of a div ingredient as follows –

div {
    width: 150px;
Enter fullscreen mode

Exit fullscreen mode

On a show of 300 pixels widths, the ingredient might take 50% of the house, whereas on a 450px decision, it can go so far as ⅓ of the width. This undeterminable rendering of parts can create advanced points on the net web page. When one in every of these parts is used, different parts will be displaced from their respective areas. For instance, CTA buttons will be displaced from their meant positions.

The next desk researched by Worship reveals the preferred resolutions we want to remember whereas performing cellular internet testing.


Whereas this may be taken as a wonderful reference. As a tester, you need to at all times analyze your personal web site’s analytics if it has already been revealed. If not, these resolutions can cowl a serious section of cellular units.

For tablets, Statcounter brings out the preferred pill sizes in January 2022. Due to this fact, these tables can suffice for this cellular internet browser testing section.


Working System

Fortunately the cellular machine market is dominated by solely two working programs — Android and iOS. Naturally, this reduces the working system mixture till we understand that they each launch a brand new model regularly to their customers.

With each new model of an working system, the corporate deprecates just a few of the functionalities as a consequence of a number of causes.

As an illustration, in API degree 24 of Android, Google deprecated the assertHorizontalCenterAligned perform. Such features primarily have an effect on the native purposes fairly than internet ones. However since internet purposes run via browsers native to the machine, any of those results will be related to the cellular internet.

Due to this fact, it turns into essential for builders to maintain observe of the deprecations and take a look at the web site for all of the earlier APIs in earlier variations, and so forth.


Probably the most time-consuming half is to test on web browsers. Not like working system variations, browser variations are launched extra regularly, with a median cycle of 4 weeks.

Additionally, there doesn’t exist solely a few browsers out there. Even for those who take out Google Chrome which has greater than 60% of the market share, different browsers too maintain a substantial market below their attain.


Relating to market share, browser fragmentation is far more regarding than the working system. With a 63% share out there, the next picture reveals how Google chrome’s model competes with the customers.

The truth that all of the customers don’t replace their browsers as regularly as possibly you and I do our work much more hectic than earlier than.

With every model, you’ll be able to anticipate some options to be launched and a few deprecated. This half is just like working programs. As a tester, we should be cautious about testing our cellular internet app in these browsers. The primary factor we’re taking a look at right here is property help elimination. For instance, a CSS perform filter() is supported solely in Mozilla’s Firefox browser. If the builders have saved Firefox as their major browser for growth, chances are you’ll anticipate just a few surprises whereas testing.

Impression on {hardware} programs

By way of impacting {hardware} programs, a lot of what’s coated below cellular internet browser testing will be summarized below this part.

When rendered on a cellular machine, our internet software takes assist from the machine’s {hardware}. As an illustration, your WiFi or mobile community might impression the loading time. And plenty of occasions, we are able to enhance this from our finish. For instance, making use of customized fonts on the server would possibly take a while to obtain. If the end-user is on a 2G community, the time can prolong to 2 or thrice greater than we anticipate.

Watch this video to learn to emulate community situations in Selenium WebDriver by utilizing the ChromeDevTools Protocol.

Google Analytics can higher perceive what your customers use to entry the web site. Nonetheless, it’s not at all times correct. For instance, let’s say your internet app performs poorly on a 2G community. The customers will navigate away from the web page, and you’ll not retain them as recurring clients. As a consequence of their low engagement in Google Analytics, they will not be proven within the checklist.

Is the battery drain a difficulty? This can be extra of a difficulty when testing native apps, however it’s also a difficulty when testing cellular internet. Stanford carried out analysis into the connection between battery drain and the cellular internet just a few years in the past. Whereas most individuals anticipated that commercials and {hardware} have been responsible, the analysis concluded with the end result as “poor coding selections.”


The World Huge Internet Consortium (W3C) has declared in its customary specification {that a} web site needs to be accessible to everybody, together with these with varied disabilities. In response to the doc, these disabilities would possibly fall into the next classes:

  • Auditory-Visible

  • Speech

  • Cognitive

  • Neurological

  • Bodily

These guidelines have been additionally acknowledged within the People with Disabilities Act in 1990. Since cellular visitors surpasses desktop visitors, testing cellular internet accessibility turns into much more important. Due to this fact, companies must also contain such standards whereas discussing the online software earlier than its growth.

Many individuals check with cellular internet browser testing with a single course of. These embrace browser responsive tests or simply visual UI testing and so forth. Nonetheless, a cellular web site take a look at is far more than that, and an internet tester ought to rigorously deal with every section described on this part.

Completely different approaches for Cellular internet browser testing

The enhancement in testing applied sciences has resulted in a number of choices obtainable for cellular web site assessments. These are outlined on this part.

Utilizing Desktop browsers

Utilizing desktop browsers for cellular internet testing is without doubt one of the least expensive however least environment friendly approaches.

Developer instruments choices in all of the browsers present the tester with pre-defined resolutions of varied cellular units.

It’s also possible to alter the display screen freely utilizing the facet panel holder.

The issue with this method is that it doesn’t think about {hardware} when resizing the online web page. As well as, since you might be on a desktop, you might be utilizing a desktop’s much more enhanced assets than cellular units.

One other downside with this method is the absence of a cellular working system and the lack to change between varied browser variations.

What would you do for those who wished to examine for Chrome 80? That’s one thing to consider right here.

Do you know? CSS scrollbar styling supplies a straightforward method to entry content material that isn’t seen on the present display screen. This doc appears to be like at methods of styling their shade and width.

Testing on emulators and simulators

In a cellular world, emulators and simulators are constructed to imitate the habits of a cellular machine with out really utilizing one bodily.

Since simulators don’t think about {hardware} a part of their habits, you need to ignore it. However, emulators are a possible choice. They think about {hardware} simple to put in, available, and upkeep is zero.


Emulators began implementing options like community throttling to differ the bandwidth, help for machine {hardware} comparable to a digicam, prompting the online app with notifications, and so forth. Utilizing emulators might help you perceive the habits of your cellular internet app in a short time.

The issue with emulators is — they aren’t actual units. They could provide you with a tough thought in regards to the machine, however they can not present correct evaluation. What precise {hardware} presents is exclusive and unpredictable. For instance, emulators can not swap shortly between 2G, 4G, after which no community. That is an precise situation and is confronted by customers in conditions when they’re touring.

It’s higher to make use of emulators for UI testing and render them as soon as to get an thought of the online app. Nonetheless, it’s not beneficial to depend on them for testing different functionalities.

Testing on Actual units

Probably the most naive technique of beginning cellular internet browser testing is buying or renting real device cloud and manually testing them. Testing on an actual machine is without doubt one of the greatest choices for testing cellular internet purposes in real-world eventualities to get correct outcomes. Right here you’ve got two choices — both go one after the other manually or set them up as a lab and join with a centralized system. This fashion, you’ll be able to test on mobile devices from a single system.

With out sharing any exact statistics, our findings of cellular machine fragmentation within the previous sections reveal how powerful this choice could be. Furthermore, buying cellular units is an costly enterprise in and of itself.

On prime of procuring the units, upkeep takes a number of money and time. Cellular machine working programs and browsers are continually releasing completely different variations. You have to take a look at machine X with working system Y and browser Z with model ABC. Repeat with a unique model. Then repeat the entire browser cycle with a unique working system and so forth.

Cloud-based testing

To beat the challenges arising within the above-discussed strategies, individuals have give you a greater answer. Due to this fact, a possible choice is to decide on a cloud-based answer typically popularized as a cross browser testing platform.

Cloud-based cross browser testing platforms like LambdaTest provide to run cellular web site assessments on the cloud and, subsequently, get rid of the effort of sustaining the in-house machine labs.
