Software testing is a crucial stage of the software lifecycle and critical to any product’s success. On its own, testing is a long process filled with various complexities. However, as you develop different types of software applications, the complexity only increases.
Software applications are designed differently from each other. Based on their purpose, their expected environment, and the technology used; testing requirements vary from application to application. Because of this, it’s hard to understand testing procedures for different software applications, unless you are an experienced software tester yourself.
Mobile and web applications are some of the most common types of software applications used across businesses worldwide. In this article, we will discuss the differences between mobile and web apps and explain the testing approach for both of them.
To understand how mobile app and web app testing differ from each other, it’s important to know why web and mobile apps are distinct from each other. Knowing the subtle differences between these applications can help create an efficient testing strategy for both of them.
Compared to websites, web applications are more interactive. They give users highly robust features that a generic website cannot provide. Because you can access these applications through the web browser of your desktop or laptop, there’s no need to have special hardware configurations for these applications. Classic examples of web apps are web banking portals and webmail.
A mobile application is a software built specifically for mobile devices such as smartphones, tablets, and other mobile devices. However, mobile apps are a little different than desktop web apps, as they fall into three main categories: mobile web, native and hybrid apps.
That said, there is no standard software kit used for them. Among other mobile applications, mobile web apps are the easiest to build and test. However, at the same time, they only offer primitive functionality.
Native applications are fast and more advanced in terms of features. Unlike other applications we’ve discussed, they have to be download on the device before using them. Because these applications are platform-specific, they are built only using integrated development environments (IDEs) and specific programming languages.
For instance, native applications on Android developed using Kotlin or Java and Eclipse IDE or Android Studio. Similarly, to build applications for an Apple device, it’s essential to use the XCode IDE and either Swift or Objective-C. Native applications are more secure comparatively, offer the have the best UI/UX experience and integrate with the hardware smoothly.
After that, they are wrapped and design for a native environment, helping developers use the same code on different platforms. Although these applications render on your mobile browser, they need to be downloaded from the app store separately.
At the same time, these applications have special permissions on your phone, such as GPS, contact list, access to your camera, etc. While these applications are easier to build and maintain, they are slower in terms of performance and offer less advanced functionalities to users compared to native counterparts.

Although mobile and web app testing are different in so many ways, there are many similar processes within these testing procedures. Here are some of the most commonly used types of mobile and web app testing.
As the name suggests, functional testing is centered on the functionality of a mobile and web application. Therefore, during functional testing, testers need to evaluate whether the core functions of an application are performing optimally.
Compatibility testing is the type of mobile and web app testing that focuses on the non-functional aspects of the application. As the name suggests, the procedure measures the compatibility of mobile and web apps against specific software, network, and hardware requirements.
Performance testing is meant to evaluate how mobile and web apps function under a particular workload of users. It helps testers ensure that the application doesn’t malfunction during its operation.
The level of security in a mobile and web app is fundamental to its success. Security testing helps developing teams evaluate the authenticity, integrity, and confidentiality of the mobile and web app.
Installation testing refers to the testing procedure for evaluating the installation and removal process of the mobile and web app.
Localization testing refers to the process of evaluating whether the UI or graphical of a mobile and web app suits the language, culture, or device accessibility of a particular region.
Automated testing refers to the testing procedure where testers automate the testing process of mobile and web apps with the help of scripts.
Manual testing the type of mobile and web app testing that utilizes human experience to evaluate the functionalities of software systems thoroughly.
At the same time, however, there are many differences in testing between the mobile app and web app testing. This happens because they have differences in terms of how they cope with an Internet connection, user interaction, and compatibility issues.
On the other hand, mobile apps offer a greater scope of options for interaction. You can not only tap, swipe, pull, and pinch objects on the screen, but also can use voice commands, motion sensors, and fingerprint sensors to interact with the software. This is why testing user interaction on mobile devices is far more difficult compared to web app testing.
As the name suggests, web applications rely a lot on the internet to function on your device. This means they cannot function offline, which is the same for mobile web applications. For this reason, it’s essential for software testers to test whether an application performs well under varying speeds of Internet connections.
Moreover, not all mobile apps are meant to work 100% offline. Therefore, software testers must see whether or not native and hybrid mobile apps work well in offline mode. It’s also important to test how the application reacts to interrupted connections and how it behaves with Wi-Fi or varying bandwidth connections (3G, 4G, 5G, etc).
Web applications operate on several browsers. Therefore, they must be tested in several different browsers, something that also applies to their hybrid and mobile web application counterparts.
That said, in terms of device compatibility, web-based applications are the easiest to test. The functionality of desktop-based apps remains pretty much the same across different devices. However, a testing procedure in mobile apps is much more complicated since they are available in a wide variety of devices.
This rich range of devices gives greater functionality to mobile applications, but this also makes testing much more complex. Therefore, mobile app compatibility testers need to consider technical characteristics of every mobile device and see how different models affect the app’s behavior.
Software testers need to remember that primary memory (RAM) is different for mobile and web apps. Although some mobile devices do have 2-8 GB of RAM, the performance of some of the best smartphones pales in comparison with that of an average desktop. Because of this, if you don’t optimize your app for mobile use, it will perform significantly slower than desktop.
Additionally, mobile applications get updated more frequently than their web apps. This is why testers need to be vigilant in testing how these updates affect memory usage and storage. Designing tests for upcoming updates prepares your team for any expected performance issues.
Likewise, the storage capacity of mobile devices is significantly less than desktops or laptops. On average, smartphones have a default storage memory of 16 GB. Limited storage severely impacts the testing of mobile applications, especially when compared to the enormous amount of memory and storage web browsers enjoy.
At the same time, most mobile apps rely on advertising services to generate revenue. These services and advertising platforms can slow down browser performance, so if you are using a web-based mobile app, the performance worsens significantly.
Desktop machines don’t run on batteries. However, an app that consumes power excessively becomes a nightmare for many smartphone users. Batteries in mobile devices are often valued more laptops and other computing devices.
So when users see that a mobile app drains too much of their power, they don’t waste time deleting it. This is why QA teams need to check how the mobile app performs on a low-charged compared to a fully-charged device.
Desktop and laptop PCs are available in limited screen dimensions. Compared to that, mobile devices have a greater variety of screen sizes in this respect. This is why the QA team needs to examine certain mobile screen dimensions and ensure that the app is easy to use and all key fields are visible.
Web applications use your web browser as a means to run on your device, so you don’t have to install them on the device. This is why they work perfectly on your devices as long as your machine has minimum hardware specifications.
In contrast, you need to install mobile applications on the device to use them. For this reason, testing whether an application installs and uninstalls on a particular device type is essential for mobile app QA testers.
Doing so ensures that the application is fit for all supportive devices and the application does not crash during installation or un-installation. You should also ensure that the app folder gets deleted from the file manager once the app is deleted from the mobile OS. At least, you should prompt the user whether he or she wants to keep the data or not.
Nowadays, mobile and web apps dominate the software market. However, without extensive testing, these applications cannot perform optimally. Testing mobile applications is a lot more complex, as they have to manage different specifications, optimize notification management, and test synchronization on multi-platforms.
