Types of Mobile Application Testing

Mobile application testing is a process by which a developed application of a mobile device is tested for its functionality, usability and consistency. Mobile application testing can be automated or manual type of testing. A typical end-to-end mobile testing process should start from creating test cases of the application, performing user acceptance and finally device testing stage. Let’s see the different types of Mobile Application Testing :

1. Functional Testing

Functional testing is the most basic test for any application to ensure that it is working as per the defined requirements. Testing an application against the business requirements is called Functional testing. In simple words, testing all the specifications given by the client is functional testing. Considering mobile-specific challenges like the variety of mobile, functional testing is an extremely intensive and time-consuming task if it is done manually. With the use of agile methodology in mobile projects, smarter teams are investing time in building automated functional tests using tools. Teams can then combine automated tests with selected manual test scenarios to balance the coverage and efficiency of the functional testing.

2. Performance Testing

Performance testing is defined as testing of an application to determine how a system performs in terms of responsiveness and stability under different load conditions. It checks whether the current network coverage is able to support the application at peak, average and minimum user levels. The client-side application performance test will focus more on user experience, such as responsiveness to the user interaction.

Performance testing includes:

 checks on server connection changes to WIFI from 2G/3G or vice versa,
 application response time,
 code optimization for the CPU cycle,
 battery consumption,
 memory leaks,
 Resources like GPS, Camera etc., freed.

If the application performance is poor for the end user, they will be likely to divert to other apps and services. The application must therefore be tested with different devices and carriers depending on the county and region.

3. Memory Testing

Mobile devices have very limited memory compared to other devices, and mobile operating systems have a default behaviour to terminate applications that are using excessive memory and causing a poor user experience. It is extremely important for mobile applications to ensure that each application maintains optimized memory usage throughout the user journey. Memory testing checks for overuse of memory and not releasing it, app temporary files not cleaned, local database growing too big, and garbage generation by the app.

4. Usability Testing

Usability testing is a process in which an application is tested in the users centred environment. It focuses on measuring product’s capacity to meet its intended purpose. The goal of usability testing is to make sure that a user can complete the tasks they are expected to complete. More importantly, they must be able to do so easily and without becoming frustrated. A good user experience can be thwarted by a number of issues, including:

 Functionality: A mobile application must present the user with the appropriate functionality. If the functionality of an application is perceived as incomplete or inadequate, customers may be lost.
 Layout & Design: Good layout and design allow a user to easily complete tasks
 Interaction: The flow of an application must be natural and allow the user to easily complete tasks.

However, it is very important to get usability testing in place from the early stage of the application design, and it should not be done only when the application is completed. Usability testing requires heavy involvement of users, and the output might affect the application design, which is very difficult to change in the later stages of the project.

5. Security Testing

The objective of security testing is to check the application’s data and network security is responding as per the given guidelines or requirement. Some basic concepts in security testing are:

•Confidentiality: Does your app keep your private data private?
•Integrity: Can the data from your app be trusted and verified?
•Authentication: Does your app verify you are who you say you are?
•Authorization: Does your application properly limit user privileges?
•Availability: Can an attacker take the app offline?
•Non-Repudiation: Does your app keep records of events?

6. Compatibility Testing

In compatibility testing application is validated for different mobile devices, OS versions, screen sizes, resolutions and hardware to ensure that the application work as desired. Important checks while testing mobile app:

 Installation testing (whether the application can be installed with the required criteria).
 Uninstallation testing (whether the application can be uninstalled with the required criteria.
 Localization testing
 Interrupt Testing (Interrupt testing is about to test the behaviour of an app in interrupted situation like call accept/reject, SMS received, Bluetooth, alarm clock etc.)
