In today’s modern tech-savvy world, we all rely on apps. Whether, it’s an alarm, a workout routine, fitness, a call, or anything else. But what if these apps suddenly stop working and don’t respond as we expect? That, of course, is a turn-off! Mobile app testing is an essential component of any software development process. And ignoring or underestimating this stage can lead to two outcomes. First, you will lose potential customers; second, your brand reputation will suffer. Let’s dive deeper to understand how mobile application testing affects your business and users.
An Overview of Mobile App Testing
Mobile app testing is a process for checking mobile apps on any OS to check functionality and usability before marketing. Testing these mobile apps help you understand the flaws and verify the technical and business requirements. And you need to check its compatibility across OS versions, screen resolutions, and network bandwidth. So, it ensures the flawless functioning of the mobile app when publicly released. Additionally, many tech giants are there to offer the application by investing in the loads and high ROI. And you could also use proficient mobile testers for your application testing cycle. On a broader level, testing involves:
- The app works flawlessly across multiple versions.
- Appearance in the portrait and landscape modes.
- Validating compatibility and performance of application.
- Consistent with mobile sensors, such as GPS and gyroscope.
- Checking the app’s graphical user interface for functionality
Why is mobile app testing critical?
It is just a simple question if you lock your car door and test it, it shouldn’t get unlocked with any door key or house key! The same scenario applies to mobile apps and feature testing. Mobile app testing increases with the complexity and cost of mobile apps. In the long run, the extra work involved in quality assurance pays off. Firstly, it provides double-verification of your mobile apps. Second, it broadens your business reach across the globe.
You may have heard the first impression is the last impression it is apt for your mobile app business too. Faulty apps cause problems for users and cause them to abandon them. If the mobile app isn’t tested enough, it can cause unwanted abruptions frustrating for new users. Half of your potential customers can go away from unwanted crashes and bottlenecks. And this loss is reflected in their poor reviews, inadequate performance, app crashes, and battery drain.
Mobile app testing vs. Web app testing
Mobile applications are designed for mobile devices, whereas web apps are for web servers and browsers. The development of web and mobile apps differs. Furthermore, how users interact with these apps through gestures such as scrolling and zooming on their touchscreen sensors. Their testing methods differ from their names. Mobile app testing is testing an app across multiple mobile devices. And web app testing is concerned with validating the appearance and functionality of websites across numerous browsers.
Factors to differ these two types of testing:
Here are some aspects to determine when differentiating these two types of testing.
Cross-browser testing in web applications refers to testing applications on multiple browsers in screen size. And for testing mobile apps on various browsers and devices. This task will consume all of your time if it is not automated. Furthermore, regression test cases run in parallel on numerous devices.
Mobile apps often struggle with storage issues because of low RAM storage with different devices. But this is not the case for web apps because of ample available space.
Maintenance is the most concerning factor the users nowadays, as users are becoming impatient. And keeping them waiting is just like losing many potential users. It is especially true for web apps as opposed to mobile apps.
As you know, web apps need internet access to perform seamlessly, and mobile apps may not require it
Types of mobile apps
Here are some common categories of mobile apps:
1. Mobile web app
A mobile web app is the web version of any app available in mobile browsers. They are compatible with any mobile OS or device and are also known as progressive web apps.
2. Native app
These apps serve mobile devices and their specific OS. It uses SDKs and offers a reliable, consistent, high-user experience.
3. Hybrid app
As the name suggests, hybrid apps are a mix of web and native mobile apps deployed in native containers. It involves a mixture of web technologies and native APIs. And it is profitable and developed more quickly than native apps.
Types of Testing
Every mobile and web app uses the one size does not fit all approach. As each business has its essence, testing takes different methods for different needs. Let’s take a closer look at how these testing types are classified:
1. Usability testing
It is as simple as it gets. Usability testing refers to evaluating the applications’ simplicity. And analyze how users achieve their goals by excelling in this usability. This test offers specific, realistic situations that resemble the app’s use to that of users. When usability testing is on direct input from the end user is more reliable.
2. Performance testing
Performance testing is an essential part of mobile app testing for evaluating many factors. It includes stability and responsiveness even under workload and circumstances. It also provides solutions to performance issues before launching an application. This testing addresses performance bottlenecks within the system and overall operations that impede or halt overall performance. You can hire mobile app developer for more technical guidance.
3. Security testing
Security remains the concerning aspect of every application. And it is your responsibility to determine every security guideline in applications for users. As applications need confidential information for transactions and interactions. Users need to know the security constraints and take the guarantee of confidentiality, integrity, and authenticity.
4. Compatibility testing
As the name shows, this testing verifies the compatibility of mobile apps on various OS, platforms, devices, etc. This non-functional testing involves internal hardware requirements and network settings. And checks compatibility for seamless functioning.
5. Localization testing
This testing examines some regional aspects based on geographical locations. It is critical to test mobile apps for responsiveness to the affected location’s various linguistics and cultural elements. Currency, time zone, and location regulations are some of the essential areas that localization testing validates.
6. Functional testing
Functional testing handles the core i.e., the goal and flow of any mobile app. These services under this testing ensure the mobile app’s functionalities and responsiveness. It also determines whether the application is fully functional for users to deploy successfully.
7. Unit testing
Moving on to a different type of testing. Unit testing divides the entire application into smaller units. Businesses use this type because it is simple to identify and resolve. It also takes less time to implement and test. The app’s operation will be seamless and smooth.
8. Manual testing
It navigates the complexities of app testing and ensures that the app meets the user’s expectations. Also useful in areas where the application is not in use. QA testing professionals may work in short bursts to examine an application that could provide results.
9. Automation testing
Mobile app testing for quality is exhausting for its complexities and time consumption. Automation testing tools are for your rescue for quick conducted tests. It offers to guarantee quality and better products quickly.
Test cases for different scenarios
So, we’ve arrived at the crucial stage of app testing: creating test cases. Test case refers to a series of test steps and data for validating application conditions. And test scenarios are the conditions to include in the test cases. These test cases changes with the different approaches. Test cases involve variables evaluating expected and actual outcomes. Software engineers run these test cases for iOS and Android with the testing tools available for these OS.
Run these tests on real devices and different kinds of apps. So, that is to get an expected result on future performance on the user’s end. Some other mobile testing areas should ensure that apps work in sync with all functionalities and features in any mobile device.
Levels of Mobile App Testing
We have come very far, and here are some testing levels to accomplish. Testing is not a term; instead, it improves the quality of any application. And to achieve perfection, every stage in software development should undergo testing.
Let’s see which testing is implied on which level.
1. Design the app tests
You are developing mobile apps for your users, and you have the test these apps to verify user experience. It should cover minor to massive changes like font, button size, navigation, etc. And mobile controls, settings, and these all should be enticing to users. Testers use A/B testing to compare designs and techniques for improving the customer experience.
2. Integrate third-party apps
Integration testing ensures that new code works efficiently after integration. Because many developers can be working on one project and integration testing confirms all modifications do not cause abruptions. Many mobile development teams use an integration environment to make this process more efficient.
3. Test functional and non-functional cases
So this category tests the functional and non-functional elements like user interface, UI layouts, and structure. And how the functionalities and the screen responsiveness to changed resolution.
Non-functional testing involves operational, interrupt, security, and performance testing. But it also includes app performance, battery usage, low resources, leakages, etc. So these test scenarios need to be handled carefully for utilization.
4. Analyze user acceptance
It is simple as it gets user acceptance and refers to validating the app functionalities to user expectations. Such as its usability, performance needs, and consistent UI across platforms.
Testers use beta testing on real devices to experience how end-users will use it on different OS.
Firstly, we used testing during the design and integration phases. Secondly, we can perform functional and non-function tests. Finally, perform acceptance testing for testing mobile application errors.
Strategy to use for Mobile application testing
And this strategy ensures quality assurance of your mobile applications to achieve business goals and market trends.
1. Selecting the device model

2. Choose the testing type
How do you test all of the devices with a single tool? End users use various devices, and it’s your responsibility to provide a unified experience. You should select any testing based on its type and variety. Manual, automated, and emulator testing are also options. It aids in identifying potential flaws and efficiently achieving the application goal.
3. Design of test case
A test case is a series of steps that help in the execution of a specific application test. Test scripts and test cases are nearly identical. Test cases are used during manual testing, whereas test scripts are in automated testing. The design of testing scenarios, test cases, and scripts are critical for the application’s smooth testing. You can hire a mobile app developer for more technical guidance.
4. Structure of testing environment
A testing environment is a process of designing devices and platforms for testing. And the testing environment is determined by the mobile apps. Setting up the proper test environment is critical for app testing success.
Common mistakes to avoid in mobile app tests
Here are some errors you should avoid while testing any app.
- When without deciding the purpose of an application, starts testing mindlessly. It is a common struggle not to be clear about the audience and expectations. And this confusion can lead to severe consequences. You should know how this will impact your business and other goals.
- Avoid overburdening the testing. Testing demands complete focus, which aids in the discovery of bugs to be resolved. Modern-day releases will always keep you on your toes, and you must decide which is most important first.
- Using only emulators for testing has several drawbacks. First and foremost, it exhibits errors in replicating device functions and will not produce the desired results. You should test mobile apps on various devices and operating systems.
- The user interface (UI) defines the entire app, but it is not the only concern of testing. It necessitates rigorous testing while considering other features, APIs, and the backend. An interactive UI combined with a shaky backend will eventually cause the app to crash.
- You determine what you will test. Design a plan about which features are for the sprint, get the scripts and scenarios ready, and understand them. Modern apps have so many features which can be overwhelming for the testers. Take the assistance of mobile application testing services for more professionalism.
