Tutorial #1: Introduction to Mobile Application Testing
Gone are the days when telephones only sat in corners, waiting to catch our attention by ringing, or when only a few individuals used computers. Today, mobile devices are extensions of ourselves and serve as windows to the world and obedient virtual assistants.
Computers revolutionized our thought processes, behaviors, learning habits, and existence.
Presently, mobility solutions rule the roost. People prefer using their handheld devices rather than starting their laptops or computers. Therefore, the mobile solutions we provide to our clients must be tested rigorously. This tutorial targets those already in the mobile testing field or those who recently shifted to it. We won’t go into definitions of mobile testing terminologies as they’re already covered in many tutorials; instead, we’ll focus straight away on the objectives of this tutorial.
As an introduction and guide to Mobile Testing, this tutorial is worth your time!
Varieties of Mobile Testing
Mobile device testing focuses on two main aspects:
#1. Hardware testing:
This involves scrutiny of the internal hardware components such as screens, processors, memory, cameras, etc. Sometimes, this is referred to as “Mobile Testing”.
#2. Software or Application testing:
This deals with examining the applications running on mobile devices and differentiated from hardware testing by the term “Mobile Application Testing”. Here are some foundational differences:
- a) Native apps: Specifically designed to function on a particular platform like mobile phones or tablets.
- b) Mobile web apps: These are server-side apps that can be accessed through mobile browsers over different networks.
- c) Hybrid apps: These represent a fusion of native and web apps, developed using web technologies like HTML5 and CSS.
Differences among these types of apps include platform affinity, development technologies, installation prerequisites, offline capabilities, etc.
Relevance of Mobile Application Testing
Compared to testing web apps on desktop devices, mobile application testing presents more challenges due to factors like:
- Variety of mobile devices with diverse screen sizes, hardware specifications, operating systems, and network service providers.
- Mobile devices offer limited memory and resources compared to desktop devices.
- Not all devices get software updates simultaneously, which complicates testing across the latest and older operating system versions.
- Service disruptions in the network can affect mobile app performance and functionality.
- Ensuring sufficient testing of an app is vital to prevent financial losses, legal complications, and damage to brand reputation.
Fundamental Difference Between Mobile and Desktop Application Testing
Key differences between mobile and desktop application testing include:
- Desktop testing checks how an application performs on a central processing unit, while mobile testing examines its performance on diverse mobile devices with differing screen sizes and resolutions.
- Mobile devices possess lesser memory and processing power than desktops.
- Mobiles use different connection options like 2G, 3G, 4G, or Wi-Fi, compared to desktops that typically utilize broadband or dial-up connections.
- Automation tools used in desktop testing may not be applicable for mobile applications.
Types of Mobile App Testing
Besides functional testing, other forms of testing conducted during mobile app evaluation include:
- Usability testing: Ensuring that the app is user-friendly and offers a satisfying user experience.
- Compatibility testing: Checking if the app performs effectively across various devices, browsers, screen sizes, and operating system editions.
- Interface testing: Focusing on testing functionality of menu options, buttons, bookmark capabilities, settings, and navigation flow.
- Services testing: Evaluating both online and offline services offered by the app.
- Performance testing: Examining the app’s performance under different conditions like varied network speeds, power consumption, etc.
- Operational testing:: Checking how the app performs under real-life conditions, including analysis of backup and recovery plans.
- Installation testing: Testing installation and uninstallation processes of the app on various devices.
- Security testing: Evaluating security measures implemented in the app for protecting user data.
Strategy for Mobile Application Testing
To ensure that the application meets quality and performance benchmarks, a well-thought-out testing strategy is essential. Key steps include:
1) Selection of devices: Analyze the market to identify widely-used devices that match your target audience’s profile.
2) Emulators: Use emulators in the initial development stages for efficient and quick testing of the app. Emulators mimic the characteristics and behavior of physical devices.
3) Beta testing: Distribute beta versions of your app to a select user group for testing and feedback to identify and fix issues prior to the official launch.
4) Performance testing: Gauge the app’s performance under varying conditions such as different network environments, loads, and use-cases to satisfy performance specifications.
5) Cross-platform testing: Test the app on distinct platforms and devices to verify compatibility and uniform functionality.
6) Automation testing: Utilize automation tools for creating and executing test scripts for repeatable and complex scenarios to enhance efficiency and accuracy.
7) Network configuration: Test application performance under different network configurations like 2G, 3G, 4G, and Wi-Fi to ensure optimal performance across various environments.

Test Cases for a Mobile App
In addition to functional test cases, mobile app testing necessitates special test cases to handle unique scenarios:
- Measure the app’s power consumption by letting it operate over a substantial time span.
- Verify the app’s response time and speed under different conditions like distinct devices, network types, and memory settings.
- Assess the app’s data requirements such as whether it can download and operate on limited data plans.
- Evaluate memory requirements of the app, including memory needed for download, installation, and runtime operations.
- Test the overall functionality of the app, ensuring that it doesn’t crash or malfunction due to network outages or any other influencing factors.
Common Activities and Procedures in Mobile App Testing
The extent of testing depends on the project requirements and modifications made to the app. For small changes, sanity testing could be sufficient. However, for significant or complex modifications, complete regression testing would be advisable.
Here’s a typical testing lifecycle of an app:
Step #1. Defining Testing Types: Identify the kinds of testing necessary for the specific app and its target user base.
Step #2. Manual and automated testing: Utilize both manual and automated testing, depending on the testing methodology and available resources.
Step #3. Beta Testing: Deploy beta editions of your app to a specific group of users for testing and feedback.
Step #4. Performance test: Analyze the app’s performance under a range of conditions such as different network speeds and loads.
Step #5. Cross-browser testing: Evaluate app functionality on different browsers and platforms for ensuring compatibility.
Step #6. Launch plan: Ready the app for production by performing an end-to-end final round of testing and addressing any existing issues.
Testing Mobile Apps on Both Android and iOS Platforms
When performing tests on mobile applications for both Android and iOS platforms, it’s important to appreciate the differences between the two. Variations could occur in areas such as aesthetic appearance, app views, encoding standards, performance, etc.
Fundamental Discrepancies Between Android and iOS Testing
(Here are some principal differences that testers should be aware of):
#1) Screen size and resolution: Android devices are available in a broad spectrum of sizes and resolutions, unlike iOS devices that have fairly standardized screen sizes.
#2) Image resolutions: Android needs multiple image resolutions (1x, 2x, 3x, 4x, 5x), while iOS only requires 1x, 2x, and 3x.
#3) Performance: Android devices with lower specs might demonstrate slower performance as compared to some iOS devices.
#4) Software upgrades: Android devices receive software upgrades at varying times, depending on the device manufacturer, which makes it tough to test on different OS versions.
#5) App compatibility: Some features and functionalities might be different between Android and iOS devices, requiring adjustments or additional testing for cross-platform compatibility.
#6) App permissions: Android and iOS manage app permissions differently, thereby requiring separate testing for each platform.
For thorough testing on both platforms, it’s critical that mobile testers are familiar with these disparities.
