The Ultimate Breakdown of Mobile App Testing_ Types and Approaches.pdf
- 1. The Ultimate Breakdown of Mobile App Testing: Types and Approaches Introduction Mobile phones have become indispensable today, with millions of apps available on the market. Mobile functionality has expanded far beyond just calling and texting. However, the vast number of applications necessitates various types of mobile testing. Imagine a day without your mobile phone—it seems nearly impossible. With mobiles differing in models, screen resolutions, operating systems, and network types, ensuring that an application performs well across all these combinations is challenging. This is where exhaustive mobile testing becomes crucial.
- 2. This blog will explore the different types and approaches to mobile app testing for applications and hardware. Understanding Mobile App Testing Mobile app testing is a meticulous procedure to ensure they meet high standards in quality, usability, and user satisfaction. This process entails thorough evaluation and validation across diverse devices, platforms, and operating systems. Its goal is to identify defects, enhance performance, and provide users with a seamless experience. Importance of Mobile App Testing The rising popularity of mobile phones has resulted in a daily surge of new applications driven by user ratings and reviews. Ratings and reviews depend on the application's functionality, making mobile application testing crucial. Testing becomes mandatory in software development with different mobile phones running on various operating systems and featuring different screen sizes. App updates are essential for user engagement, as bug fixes ensure app retention and market sustainability. Evolution of Mobile App Testing Previously, mobile app testing primarily focused on functional testing, ensuring that apps met their intended purposes. However, testing approaches have evolved significantly. Today, mobile application testing encompasses various types of testing to deliver an exceptional end-user experience.
- 3. Understanding the diverse types of mobile app testing and their unique contributions is essential for ensuring the success of mobile applications in the market. Types of Mobile Apps: Native, Hybrid, and PWA Mobile app testing companies typically engage with three primary types of mobile applications: ● Native Apps: They are designed for a particular platform like Android or iOS, leading to distinct applications for each platform. ● Hybrid Apps: These applications are versatile and compatible with both Android and iOS platforms. They achieve this by combining native and web elements in development. ● Progressive Web Apps (PWAs): These apps function as both regular mobile applications and separate websites simultaneously, offering a seamless user experience across platforms. Testing Approach for Native and Hybrid Apps While native and hybrid apps use different underlying technologies, the testing approach remains similar. Functional checklists and test cases focus on traditional evaluations. However, performance issues are more common in hybrid apps due to the integration of web technologies within a native shell, potentially impacting responsiveness compared to native apps. Additionally,
- 4. UI testing is more time-consuming for hybrid applications due to the need to accommodate various Android and iOS screen sizes and resolutions. Mobile App OS: Android vs. iOS Testing Testing processes for Android and iOS apps are generally similar, with the main difference being the time required for testing. Android app testing typically requires more time due to the broader variety of devices and OS versions. Android devices come with a vast range of screen sizes, resolutions, software, and hardware configurations, leading to more layout issues, interface bugs, and a more extensive scope of UI testing tasks than iOS. Compatibility and performance testing for Android apps also require more time due to the multitude of software/hardware combinations available. Approaches to Mobile App Testing Regarding mobile app testing, there are two primary approaches: proactive and reactive. Proactive Approach The proactive approach involves starting the test design process early to prevent issues before the code is ready. Instead of waiting to check a mobile application's final or near-final version, the QA team begins with a requirements review. This approach helps prevent bugs rather than just finding them, shaping software quality from the outset. Reactive Approach
- 5. Conversely, the reactive approach involves working with the end product, assuming its design and functionality are ready for use. Testing is conducted at a late stage of the Software Development Life Cycle (SDLC), reacting to the quality of the delivered product. Different Techniques for Mobile App Testing There are two fundamental testing techniques: static and dynamic testing. Static Testing Static testing involves examining an app without executing the code. Experts review the code to find errors within the foundational layer of an application, focusing on establishing requirements and documentation to prevent issues. Dynamic Testing Dynamic testing involves evaluating an app during its execution. QA engineers check the app's functions and layers—from unit to user interface—guided by designed testing data. This method is highly compatible with mobile automation testing. Different Types of Mobile App Testing 1. Functional Testing: This focuses on testing an application's primary objective and flow and verifying features and specifications.
- 6. 2. Usability Testing: Evaluates the user-friendliness of an app, focusing on human experience and real-device testing. 3. Performance Testing: Checks an app's stability, responsiveness, and speed under different workload conditions. 4. Security Testing: Ensures the app's security against cyber-attacks and data leaks, critical for user trust. 5. Interruption Testing: Ensures the app functions correctly despite interruptions like calls, messages, or low battery. 6. Compatibility Testing: Ensures the app works across various OS versions, devices, and network environments. 7. Localization Testing: Tests the app's adaptability to different languages and geolocations. 8. Speed Testing: Checks the app's opening speed compared to previous versions and competitors. 9. Installation Testing: Confirms that the app can be installed, uninstalled, and updated seamlessly, without encountering any errors. 10. Memory Leak Testing: Identifies if the app fails to release temporary memory, which can lead to performance issues. 11. API Testing: Evaluate the app's communication with external services for functionality, performance, and security. 12. Build Testing: Tests critical issues associated with an updated mobile app build before release. 13. Role Testing: Verifies if different application users can access their entitled experiences and data.
- 7. 14. Stream Testing: Ensures reliable audio and video content delivery in the app. 15. Manual Testing: Human-driven process focusing on user experience, suitable for exploratory testing and user-friendliness checks. 16. Automated Testing: Test scripts are used to automate test cases, covering 80% of the testing process for efficiency and regression testing. Challenges in Mobile App Testing 1. Device and OS Fragmentation: Testing across different devices and operating systems (OS) to ensure compatibility and functionality. 2. Network Variability: Ensuring consistent performance under different network conditions, such as 3G, 4G, and Wi-Fi. 3. User Interface Consistency: Maintaining a uniform user experience across different screen sizes as well as resolutions. 4. Security Vulnerabilities: Protecting sensitive data, while ensuring robust security measures against cyber threats. 5. Adaptability to Updates: Keeping pace with frequent operating system and app updates to maintain app functionality and compatibility.
