consistency across various mobile devices. Regardless of the device used to access the app,
it ensures the best user experience. Here is everything you need to know about mobile app
testing, how to do it correctly, and why it matters for teams and developers creating more
device-independent mobile apps.
What is testing for mobile apps?
Mobile app testing, as the name suggests, is the procedure of evaluating an Android or iOS
mobile app for usability and functioning prior to its general release. Mobile app testing
enables users to confirm whether an app satisfies the expected business and technical
criteria.
Teams must test apps across a range of screen resolutions, operating system iterations, and
network bandwidths in order to conduct successful mobile app testing. When the app is
made available to the general public, this helps to assure flawless performance across a
variety of device setups.

Why is testing mobile apps important?
Creating mobile apps has as its ultimate objective expanding corporate reach to more users
worldwide. However, if the software is broken or challenging to use, people are unlikely to
use it. Naturally, no company wants their clients to uninstall their apps and use a rival.
If mobile apps are not fully tested, there is a great likelihood that users could run into
serious issues on their device, which could make for a poor user experience—especially for
novice users. Keep in mind that each mobile app's success depends largely on its first
impression. Any unanticipated app crash or fault in the functionality of the program can
result in its instant deletion. Here are some important figures that demonstrate the
importance of mobile app testing:
 Eighty percent of users delete or uninstall an app if it falls short of their
expectations.

3.  50% of users tend to remove apps that take up too much space from their devices.
 If an app is too slow, 48% of customers remove it or stop using it.
How can app testing help your company?
End users in the real world can download and utilize the app on any of the more than 9000
different mobile devices. It goes without saying that the program must be sufficiently
customized for that specific device in order to function properly.
Mobile device usage has surged as a result of smartphones' ongoing growth. Global mobile
user numbers are anticipated to reach 7.5 billion by 2026. When compared to the 3.6
billion smartphone users in 2016, that is a twofold increase. The statistics unmistakably
show that the use of mobile devices will increase significantly in the near future. The
popularity of mobile devices will also SEO Expate Bangladesh Ltd encourage the creation of
cutting-edge mobile applications that will increase access to corporate services. Mobile app
testing enables the verification of an app's appearance, functionality, and performance on a
variety of devices. Apps that are optimized for popular mobile-OS configurations among
their target market enable smooth user experiences across all platforms and devices. It aids
in providing new users with a rich and customer-focused experience. In other words, the
likelihood of expanded outreach is higher the better the user experience.
What distinguishes testing for mobile apps from testing
for web apps?
Mobile applications are created and developed specifically to work on mobile devices. Web
apps, on the other hand, are software programs that live on web servers and are accessed
using web browsers. The construction of web apps and mobile apps differs greatly from
one another. Additionally, users interact with them differently because mobile users utilize
touch-screen mobiles to zoom, pinch, and scroll. Naturally, the techniques used to test them
also vary as well. Web app testing focuses on validating the appearance and functioning of
websites across various browsers, whereas mobile app testing refers to evaluating an app
across a variety of mobile devices.

4. Different Mobile Apps
Mobile apps can be broadly divided into three types:
Web app for mobile
Mobile web apps are responsive variations of websites that can be accessed using mobile
browsers or inside of a web view. Any mobile device or mobile operating system can use
them. They go by the name Progressive Web Apps as well.
A native app
For mobile devices and their operating systems, native apps are created. Native apps
provide a more dependable, quick, and intuitive user experience because they are created
with particular SDKs.
App hybrid
Mobile web and native apps are combined to create hybrid apps, which are installed in
native containers. Web technology and native APIs are used to create hybrid apps. They are
affordable.
How often is cross-browser testing performed?
Teams must conduct an audience analysis on their platform before beginning mobile app
testing. The following are evaluated with the aid of audience analysis:
 popular mobile devices in particular regions
 versions of Android or iOS that are quite popular
 screen resolutions that are highly favored
 Combinations of devices and operating systems that the target audience most
frequently uses

5. Teams can begin testing apps after completing the necessary research by creating a list of
device-OS combinations to test first. Teams can choose to use an on-site mobile device lab
to execute tests, or they can use a cloud-based platform like Browser Stack, which provides
a real device cloud for testing mobile apps under actual user circumstances.
Both manual and automated app testing are supported by the infrastructure of Browser
Stack. This means that one can SEO Expate Bangladesh Ltd use automation frameworks like
Appium to execute automated app tests across devices, or they can opt to test their apps
manually on specific Android or iOS devices.
The methods listed below should be followed in order to manually test apps on a few
genuine devices:
 Free registration at Browser Stack App-Live.
 Obtain the App-live dashboard's address.

6.  Install the software (.apk or.ipa) directly from the Plays tore or Appstore, or upload
it from the computer.
 Select the chosen mobile device (such as an iPhone X) and operating system
(Android or iOS).
Start evaluating apps
For more information on how to manually test mobile apps using Browser Stack, please
refer to this comprehensive guide. On-premise device lab testing can get very laborious at
times because it necessitates periodic updates to the OS and handsets. Additionally, small
and medium-sized businesses cannot afford to set up an on-site device lab because it
demands a significant investment. By choosing a cloud-based testing platform like Browser
Stack, all these issues may be solved.
What aspects of an app are evaluated?
Realistically, it is impossible to thoroughly test a software before making it available. High
customer expectations force developers to deploy apps on constrained timelines, which
leaves them little time for comprehensive QA operations at once.
To start, determine which features are most significant to the app's intended user base.
Common aspects like user interface (UI), design, theme, security, and fundamental
functioning should come first. Let's use an eCommerce app as an example. The product
catalog, the Cart, and the payment system would be considered the most crucial elements.
Given the time constraints at hand, these must first undergo thorough testing.
Start the QA process with a systematic plan that classifies features according to priority in
order to organize the procedure. Asking a control group of potential users what they
believe to be the most important features of the app being created will help you shape your
test plan.

7. Then test the app using actual mobile devices and real-world scenarios. The question of
"how to test a mobile app on multiple SEO Expate Bangladesh Ltd devices" needs to be one
that QAs start asking themselves. Without actual device testing, QAs risk missing important
user journey components that need to be validated first. Get some potential users to test
the app, if at all possible. Because they are the ones using the app, potential customers can
more easily spot any problems or abnormalities with its workflow or design.
Who conducts testing of mobile apps?
Mobile app testing is carried out by everyone who wishes to publish a profitable, optimized
mobile application. Mobile app testing are often carried out by a dedicated team of QAs for
each sprint by app development teams. Testing of mobile apps frequently includes non-QA
stakeholders, such as developers, managers, product owners, and future consumers.
In reality, since it considers diverse viewpoints, mass involvement in mobile app
assessments is highly advantageous. Product managers will be in a better position to
provide non-technical insights than QA managers. Having people from various jobs weigh
in on the app's functioning will help it become a more well-rounded product likely to
appeal to more customers because a good app needs to be much more than just technically
effective.
BrowserStack is the solution if you don't know how to write and are wondering how to test
mobile applications. To use interactive cross-device testing tools, you don't need to know
how to code. For instance, marketers and web designers utilize BrowserStack App Live to
quickly test apps for responsiveness and cross-device rendering. To ensure that the build
fulfills device compatibility criteria, quality assurance teams typically run test scenarios on
a variety of devices.
How do I choose the best gadgets for testing mobile
apps?

8. In a word, investigation. Analyze your app's target market before you do anything else.
Learn as much as you can about the consumers' general preferences, preferred devices,
operating systems, and geographic locations. As a result, QAs will be able to optimize their
processes and better cater the app to the requirements and expectations of customers.
Refer to your traffic statistics and combine those learnings with our Test on The Right
Mobile Devices report—which combines device usage data in various markets—to make an
informed decision tailored to your target audience.
The Business and Marketing teams (or the client) typically decide which devices to test on.
These teams' objectives aid in concentrating the product/testing team's efforts where they
will be most beneficial.
Typical errors to avoid while conducting mobile app
tests
Without having a clear understanding of the app's goal, don't begin testing. What is the
purpose of it? The target users are who? What goals do users have? What are the app's
expectations from the product managers and other management levels? Before engaging in
QA efforts, these questions must be addressed.
Avoid attempting to test everything at once. That is not humanly feasible given current
delivery dates, as was previously stated. Test the most crucial items first.
using solely simulators and emulators for testing. Compatibility and performance tests
can't be done on them since they have major limitations when it comes to simulating real
device functions, which prevents them from producing reliable results. Apps must be tested
on actual mobile devices made by SEO Expate Bangladesh Ltd various manufacturers. Don't
just concentrate on the UI. Now that the UI is essentially the app's face, it is unquestionably
the most crucial component. Careful testing is necessary. Don't forget to thoroughly
examine both the backend services and the APIs, though. If the software crashes frequently
due to a bad backend, even the best user interface is useless.

9. Without a plan, don't move forward. Select the features that must be tested during each
sprint, decide on the tests that must be performed, develop scripts, and be aware of the
precise outcomes that must be achieved. Modern apps have far too many features, making
it impossible to thoroughly evaluate them without a structure.
Techniques for Testing Mobile Apps
Mobile app testing can be made more effective by using the following techniques, which are
also part of a success-driven QA strategy:
 Be transparent about the difficulties, particularly the degree of device fragmentation
and the requirement for the appropriate frameworks and tools.
 Ask the correct questions before putting a strategy on paper, such as "how to test
mobile apps on desktop" or "how can unit testing of mobile apps be done"
 Use emulators and/or simulators exclusively during the testing phase. Without
testing it on actual devices, an app cannot be published successfully. Without testing
in actual user circumstances, an app is more likely to have major issues and offer
poor user experiences.

10.  Spend money on beta testing. similar to actual device testing beta testing is the
greatest technique to measure user acceptance and the real-world performance of
an app.
Include QA teams from the beginning of development along with the business and product
teams.
How can Browser Stack assist in testing mobile apps?
Simple. You may test mobile applications with Browser Stack on actual mobile devices. As
previously said, it is difficult to release a mobile without first evaluating how well it
performs in actual mobile device conditions. Teams and individual testers can access
3000+ genuine Android and iOS devices on the cloud for manual and automated testing by
