Mobile App And Web App Testing: Differences You Need To Know

The Role of Web Applications

Web applications are programs you may access using a web browser and store on remote servers. You can use various browsers (Chrome, Safari, Firefox, and more.) to access these applications that developers build with standard web technologies like HTML, CSS, and JavaScript.

You can access properly optimized web apps from any internet-enabled device, including smartphones, tablets, and personal computers.

Mobile Apps

A Mobile Web Application (or simply Mobile Web App) is a web-based application you can access using a mobile web browser. Web apps may look like mobile apps, but they perform very differently.

Native applications are apps developed specifically for a given platform and distributed through that platform’s app store. Developers write these programs in specialized languages for Android and iOS. Teams use the Objective-C programming language to create iOS apps, while they use Java to develop Android apps. Due to the need for separate code bases for iOS and Android, developing such apps takes time and effort.

To create a hybrid app, developers use significant features from online and native apps. They use several frameworks to take the conventional web stack (HTML, CSS, and Javascript) and encapsulate it in a native environment.

These programs are similar to native apps in that you can download and run them on a mobile device, and they may use the device’s various sensors and functionalities (camera, GPS, contact list, and more). They’re far more straightforward to create than native apps, and you can use the same code for Android and iOS.

Let’s dive into the differences between testing for mobile and web apps and see where we find ourselves.

Testing web applications guarantees that they work properly and without errors on all supported browsers and devices. However, mobile app testing discovers compatibility issues in hybrid or native apps across various devices.

Teams need the correct combination of tools to achieve faster, more efficient, and the highest possible test coverage if they want to succeed.

Test Automation Frameworks and Tools for Web Applications

Web app testing aims to release apps that work consistently across browsers. It also seeks to guarantee that web apps function faultlessly regardless of the device being used to access them.

Though there are other commercial options, Selenium has long been the favorite set of tools for quality assurance. It enables QA specialists to automate UI testing on websites in all the major browsers. By employing a Selenium Grid, QAs can simultaneously test in several environments of their choosing.

Using Selenium, QAs can also mimic real-world user behavior by simulating clicks and taps on a virtual keyboard and mouse. The fact that Selenium works with many different languages is a significant factor in its success; this streamlines the process of creating test cases for the testers.

Mobile Application Testing Frameworks and Tools

The mobile app ecosystem is intricate and comes with various apps. Mobile apps can be either native, hybrid, or mobile web, and testers need to know which type they’re dealing with before beginning their work.

The following are examples of well-known tools that you can use to do automated tests for native, hybrid, and mobile web apps.


Appium, an open-source tool built on Selenium, is widely used to test cross-platform, native, and mobile web apps. This application allows users to automate test scenarios on real mobile devices, emulators, and simulators for iOS and Android apps. Testing automation specialists must develop unique test scripts for each platform. Also, Appium gives QAs the freedom to pick their preferred programming language.


Google created the open-source framework Espresso for Android app testing. You can create Android native apps with the help of Espresso. The framework’s automated synchronization and user-friendly API are two of its greatest strengths. Espresso supports both Java and Kotlin for creating test cases.


The XCUITest framework for user interface testing comes with the XCode integrated development environment. For native iOS apps, it facilitates the automation of UI testing. There are just two supported programming languages for XCUITests: Objective-C and Swift. Developers recognize this framework as the fastest and most reliable for executing iOS tests.

Why You Need Real Devices to Test Your Mobile and Web Apps

The only reason to use automation is to speed up feedback and improve accuracy so that you can create flawless software. You can meet this goal by putting real devices through the paces of test automation scripts. The findings of such testing will more closely resemble those in the actual world if you conduct them under realistic user situations.

To test with actual devices, you will require an on-site device lab. However, this calls for huge investments, making it impractical for small businesses. Choose an automated software testing platform, like HeadSpin, to get around this problem.

As was previously noted, the mobile-first ecosystem is rapidly becoming the norm in the digital world. Business success today requires an equal emphasis on mobile and online app testing methodologies. Businesses may confidently serve a wider audience if they strike the correct mix between the two and test their products on real devices.
