Smartphones have changed the way humans interact with technology. Be it travel, fitness, lifestyle, video games, or even services, it’s all just a few touches away (quite literally so). We only need to look at the growing throngs of smartphone or tablet users vs. desktop users to grasp this reality.
According to a survey, there were over 54.57% mobile users compared to 42.66% of desktop users from April 2021 to April 2022. With easy access to fast Internet and the massive variety of cheaper smartphones available today, these numbers are bound to bend significantly towards mobile usage in the future too.
Traditionally, web applications were the significant application type in most businesses. However, unlike run-of-the-mill HTML, JavaScript, and CSS web apps that run on a browser, there are now mobile applications capable of running on hand-held devices. This has also led to a rapid change to a mobile first strategy for business across all industries.
But conquering the mobile-app-focused market isn’t so easy, especially when it comes to mobile app testing, which is essential in building a top-notch mobile app. Even more interesting is there’s a whole world of difference between web and mobile application testing!
In this article on the difference between web and mobile application testing, we explore the difference between web and mobile application testing to help you strategize your mobile and web app testing for maximum results.
How different are Web Apps and Mobile Apps?
Both web applications and mobile apps are indeed used to improve the efficiency of business processes. However, they are different in terms of their architecture and delivery mechanism, which leads to a difference between web and mobile application testing.
Before we deep-dive into the difference between web and mobile application testing, let’s see what web and mobile applications are.
What are Web Applications?
A web application is an application that runs in the browser and does not need to be downloaded. Web applications are a collection of programs or services that use the Internet to deliver information to users. Each web application consists of an interface, which can be accessed via a web browser, and a back-end server that manages the data and executes specific processes.
Web applications can create powerful, stand-alone tools for a specific purpose. For example, Gmail is an email web application that replaces the need for a desktop mail client and stores emails on Google’s servers. Another example of a web application is the OTT (over-the-top) platform Netflix built with the sole purpose of media streaming through a browser.
Applications are usually built in some specific programming language. The most popular are JavaScript, C#, Python, and PHP. Web applications can also be standalone programs accessed from a web browser but run on servers elsewhere. Some specific web applications are also called “Rich Internet Applications” (RIAs), especially when they employ advanced technologies like AJAX, Flash, or Silverlight.
What are Mobile Applications?
Mobile applications, also referred to as apps, are software programs designed to run on small mobile devices like tablets and smartphones. Mobile apps run on an operating system and can be downloaded from a store, such as the Apple App Store or Google Play Store. These programs provide users with tools and services to help them accomplish tasks.
Mobile applications extend the functionality of mobile devices, such as providing the ability to run a wide range of applications, use Internet services, send and receive emails, and text messages, take pictures and videos, play games, calculate mathematical problems, read books, access social networking sites and much more.
Mobile apps are usually made for specific mobile operating systems, such as iOS, Android, Windows, and specific devices like tablets or phones. They can be free or paid and may or may not require a subscription. Applications are either pre-installed on phones during manufacture or installed later.
Mobile apps can be further categorized as mobile web applications, native applications, and hybrid applications.
- Mobile web applications are similar to web applications, only that they run on a mobile browser. These web applications don’t require any downloads or installations. In simple terms, these applications can be defined as super-responsive websites that are very flexible when adapting based on user expectations or requirements. While this is a significant plus point for mobile web applications, there is a dark side as well- the performance of these apps entirely relies on a device’s browser and an Internet connection, which could impact the user experience for every other user. Progressive Web Apps (PWAs) are among the most commonly used types of mobile web applications.
- Native mobile applications are designed to run on specific devices. They can be developed using native languages for each platform (Objective C for iOS and Java for Android) or cross-platform development tools (Phone Gap). These are standalone applications explicitly built for different mobile OS such as iOS or Android. Native apps are often built to be reliable and faster than other applications. But that also leads to a higher cost of native app development and production.
- Hybrid applications are built like mobile web apps with the capability of running like native mobile apps, i.e., in a native environment. These apps often look like web applications yet have all the perks and features offered by native mobile applications. Hybrid applications offer users the best of both worlds- minimum load time and consistent user experience even during poor Internet connection.

Difference between Web and Mobile Application Testing
Testing is the process of evaluating a software application for compliance with specific criteria. This process helps ensure that software- be it a web app or a mobile app, meets the required standards and performs as expected. In the last section of this article on the difference between Web and Mobile Application testing, we explained how different web and mobile apps are. Hence, it’s easier to understand that the difference between web and mobile applications comes down to their complexity, purpose, and intended users.
Web application testing involves testing web applications for quality, functionality, usability, etc. This could involve testing the web app’s performance across different operating systems, browsers, and versions. and cross browser compatibility testing both help ensure that a web app is providing a consistent user experience across every possible combination of OS and browsers.
Mobile app testing is verifying whether or not an application works as intended. Therefore, before releasing a mobile app, it is essential to ensure that it performs up to quality standards and does not contain any bugs that could hinder the user experience.
While web application testing has been an essential part of conventional software testing, mobile app testing is often left wanting more. Even though mobile application development is a booming business, many well-known companies like Instagram, Snapchat, Twitter, and Facebook are ruling with their apps.
There are many essential differences between web and mobile application testing.
- Compatibility– The most crucial difference is the screen size. A web app can be viewed on various devices and screen sizes, whereas a mobile app will only fit perfectly on its target platform, i.e., a mobile device. The battery life and storage capacity of desktop computers or mobile devices also impact the performance of respective apps. Web apps are pretty easy to test owing to a lack of compatibility issues. On the other hand, mobile apps are built with complex architecture. They are expected to be compatible with multitudes of devices, making mobile app testing quite intricate.
- User Interactions– Web apps are built to offer a limited variety of user interactions, with a keyboard and mouse input still being the standard. These interactions are pretty easy to predict and comparatively easy to test. On the other hand, the expected user interactions for mobile apps are almost labyrinthine- be it swiping, pinching, voice-based interactions, or even hand wave gestures, complicating mobile app testing further.
- Internet Speed/Availability– When it comes to web applications, there are two types: those that need to be online to work and those that can function offline. The vast majority of web applications – around 95% – are of the first type and require a constant Internet connection to work. The same rule applies to mobile applications, and most of them don’t work offline. Therefore, to ensure a web app or mobile app performs well regardless of the Internet connection speed (or the lack of it), it becomes imperative to test it with different speeds.
To ensure that users get the most of your web app or mobile app, it is essential to pick the right tool, especially after considering the complications associated with mobile apps.
