Software applications lie at the core of
any IT infrastructure and help the latter to function as per expectations.
These help organizations and enterprises to achieve their digital
transformational goals including the delivery of superior customer experiences.
To ensure such applications deliver value for money and do not run the risk of any
failure, they are subjected to several rounds of testing. Importantly, the
customers of today access applications on a plethora of device platforms,
operating systems, databases, browsers, and networks, among others. They expect
the applications to perform uniformly across platforms and can summarily
discard them in the event of any malfunction or quality issue. Compatibility
testing entails the testing of software applications across digital
environments to validate their performance. It is a necessary cog in the wheel
for digital transformation
implementation.
Why mobile compatibility testing?
Mobile applications have become a rage
among people on-the-go. They have brought the fruits of digitization to the
people at large and enabled them to buy products, access information, or avail
services, quickly, securely, and conveniently. However, the biggest challenge
testers face in validating any software is the multiplicity of devices. For
example, the number of mobile devices is projected to touch a whopping 16.8
billion in 2023 (source: Statista.) These devices are of different brands,
features, hardware configuration, software and firmware requirements, screen
size, and network operators, among others.
So, not only the mobile devices have
issues of compatibility with their competing brands but can have differences
with their brand line as well. This is where a special type of testing called mobile
compatibility testing comes into play. It focuses on testing the compatibility
of mobile apps across device platforms, software, firmware, operating systems,
browsers, databases, and networks, among others. An application compatibility testing process ensures the seamless
performance of application across these digital elements.
Types of compatibility testing
Any device compatibility testing allows developers and testers to
achieve improved application performance. It consists of two types:
Forward testing: The testing
validates the compatibility of an application with newer versions of operating
systems.
Backward testing: Here, the testing
process validates the compatibility of the application designed with the latest
environment version with that of its older version. For example, if the
backward testing of an application is conducted for Windows operating system,
its compatibility should be tested for both the latest Windows 10 version as
well as the older ones like Windows XP, Windows 7 etc.
What happens if compatibility testing of applications is skipped?
Customer experience has become the
differentiator for software applications to be adopted or discarded. It is
directly related to the performance of any digital company in the market.
Simply put, if the customer experience offered by any product is below par, the
company can lose its position in the market. And one of the prominent
attributes leading to excellent customer experiences is the product’s
compatibility across platforms. These platforms could be the operating systems,
their newer versions, browsers, hardware configuration of devices, and mobile networks.
If device compatibility testing is skipped, the results could be
telling for the application and its brand:
Differences in UI: Each device has its
configuration for the UI interface to run smoothly. However, it would require a
particular look, feel, font size, resolution, and alignment for any application
to work. In the absence of any compatibility testing exercise, this aspect of
the application can remain unresolved for different devices.
Persistence of quality issues: Compatibility
testing helps in identifying glitches in a software application, which
otherwise can render it unsuitable to function across devices. Further, if such
glitches are not fixed in time before delivery, the cost of fixing them later
can be high. This can hit the profitability of any business big time.
Hits user expectations: The success
of digital
transformation solutions depends, to a large extent, to their
compatibility across digital environments. Users are wont to expect
applications that perform seamlessly on multiple platforms. If performance
slackens due to issues of usability, stability, and scalability, then user expectations
can take a massive hit. And in a world of tough competition where users look
for fast loading, reasonably priced, feature-rich, and functional applications
to meet their expectations, any lack of user experience can sound the death
knell for that application.
Conclusion
Digital transformation has become the key
enabler for enterprises to stay competitive and meet their objectives. However,
the software applications at the core of such transformation need to be
compatible across every digital environment. To ensure the same, digital compatibility testing needs to
be pursued vigorously across the SDLC.
