Types of Mobile Testing: How to Choose Right for Your App
Mobile devices have transformed from simple communication devices to multifunctional computing machines. One of the greatest drivers behind this transformation has been the advent of smartphones and the subsequent rise of mobile applications. As of Q3 of 2019, there had been 29.6 billion mobile app downloads in Apple and Google app stores.
These applications enable mobile devices to perform countless operations and become an integral part of our daily routine. However, mobile applications need to be fully functional to deliver value to consumers.
At the same time, mobile apps have to stay relevant in a highly-competitive market. Not only is it necessary for developers to deliver error-free mobile software, but they also need to ensure the usability, security, and quality of these applications.
Mobile testing helps mobile app developers maximize the performance of these applications. With that said, mobile testing is not a one step-operation, but rather a procedure of iterative steps that tailor the application according to user requirements.
In this article, we will discuss multiple types of mobile testing and discuss the goals and benefits of each given testing procedure.
As the name suggests, functional testing is centered on the functionality of a mobile application. Therefore, during functional testing, testers need to evaluate whether the core functions of an application are performing optimally.
Functional Testing Goals
The majority of procedures in functional testing cover components that contribute to the flow of the software and along with its main purpose. For instance, if you are developing a mobile app for an e-commerce app, you will test specific features such as sign up, log in/out, add to cart, payment gateway and other specialized operations. At the same time, it’s necessary to see whether or not the app is launching as intended; graphical components are working properly, and if the application is pushing notifications as it should.
Benefits of Functional Testing
- It helps us make sure that app consumers are satisfied.
- It rules out any functional defects in the mobile application.
- We can evaluate whether all user functional requirements were met.
- It reduces the risk of bad user feedback.
- Since we test the core functions of an application, we can make sure that the application delivers value to consumers through these features.
Usability Testing Goals
In usability testing, we evaluate the mobile application through the eyes of the end-user. Therefore, we need app consumers to evaluate the application’s intuitiveness and use their feedback as insights to improve their experience while using the application.
There is no hard-line methodology for this type of testing and QA testers often leverage their understanding of the user needs to see whether the application is up to the mark. Therefore, it’s essential to evaluate the response time of the application, its user-friendliness, as well as its layout and design.
Since the testing procedure can be subjective depending on the tester, it’s ideal to construct feedback forms and test scripts for understanding the preferences of targeted users.
Benefits of Usability Testing
- Design experts can focus on the key requirements from the end user’s perspective
- If the team disagrees with a particular design, they can reaffirm the best choice by asking the users directly
- We can detect potential issues before we launch the mobile app on the market
- It ensures that the front-end design is attractive and consumers are able to utilize the product effectively
- The likelihood of product failure is reduced
- Project teams are left with mobile applications optimized for maximum performance and high usability
Compatibility testing is the type of mobile app testing that focuses on the non-functional aspects of the application. As the name suggests, the procedure measures the compatibility of mobile apps against specific software, network, and hardware requirements.
Goals of Compatibility Testing
In compatibility testing, we must make that the mobile app works seamlessly across different operating systems, browsers, and hardware makes and models. Therefore, the testing team would see the compatibility of the application across OS such as Android, iOS, and Windows, as well as hardware specifications and changing networks and their parameters.
Benefits of Compatibility Testing
- It helps developers address issues related to the interoperability of mobile applications between different platforms

- It is directly related to the usability of the application. If done right, it can maximize user satisfaction from the application
Performance and Load Testing
Performance testing is meant to evaluate how mobile apps function under a particular workload of users. It helps testers ensure that the application doesn’t malfunction during its operation.
Performance and Load Testing Goals
Performance and load testing are directly related to the effect of user load on the performance of the mobile application. Therefore, when we conduct performance and load testing, we try to detect device performance issues as memory and battery consumption by the mobile application as well as the start-up and response time of the application.
At the same time, you can use this mobile app testing type to check the performance of the network and the under a specific user load. Therefore, it should detect issues related to errors and delays during data retrieval and the speed of data transfer.
Benefits of Performance and Load Testing
- It helps us ensure that the application I performing its core operations effectively
- We can evaluate the accuracy, stability, and speed of the mobile app
- Performance and load testing help developing teams maximize user satisfaction
- It identifies the core problems related to the performance of the mobile app and helps teams resolve them
- It enhances the optimization and load capability of the mobile application
The level of security in a mobile app is fundamental to its success. Security testing helps developing teams evaluate the authenticity, integrity, and confidentiality of the mobile app.
Goals of Security Testing
The reason why software testers conduct security testing is that they need to identify the potential vulnerabilities and threats a mobile application can have. It’s necessary to resolve these potential security risks to safeguard the personal data of its users.
Therefore, the security testing procedure of mobile apps must be able to detect complex security risks that are not apparent in the source code. Unless you identify the location of these vulnerabilities, there is no use finding them out. This is it’s essential to identify the precise location of these defects during security testing.
Benefits of Security Testing
- It ensures that the mobile application and safe and secure for its end users
- It helps businesses counter data loss and thwarts attempts for data theft
- If you detect security vulnerabilities of a mobile app in the early stages, it can result in significant benefits to the business, mostly in cost-saving
