Functional Testing :-
Functional testing is the most basic test for any application to ensure that it is working as per the defined requirements.
Compatibility Testing :-
The purpose of a mobile app compatibility test, is to ensure an app’s key functions behave as expected on a specific device, platform and OS version.
Localization Testing :-
Nowadays, most of the apps are designed for global use and it is very important to care about regional trails like languages, time zones, etc.
Laboratory Testing :-
Laboratory testing, usually carried out by network carriers, is done by simulating the complete wireless network. This test is performed to find out any glitches when a mobile application uses voice and/or data connection to perform some functions.
Performance Testing :-
Mobile performance test covers client application performance, server performance, and network performance.
Stress Testing :-
Stress testing is a must to find exceptions, hangs, and deadlocks that may go unnoticed during functional and user interface testing.
Security Testing :-
Vulnerabilities to hacking, authentication, and authorization policies, data security, session management and other security standards should be verified as a part of mobile app security testing. Applications should encrypt user name and passwords when authenticating the user over a network.
One way to test security related scenarios is to route your mobile’s data through a proxy server like OWASP Zed Attack Proxy and look for vulnerabilities.
Memory Leakage Testing :-
Mobile devices have very limited memory as compared to other computers, and mobile operating systems have a default behavior to terminate applications that are using excessive memory and causing a poor user experience.
Memory testing is exceptionally important for mobile applications to ensure that each application maintains optimized memory usage throughout the user journey. It is recommended that we conduct memory testing on the actual target device, since the system architecture is different from an emulator to an actual device.
Power Consumption Testing :-
There are several types of batteries used in different mobile devices (i.e. nickel cadmium/lithium ion/ Nickel metal hybrid). While we focus on power consumption testing, we are required to measure the state of the battery at each activity level. It will give us a better understanding of power consumption by an individual application.
Power Consumption test can be done manually; also there are some free tools available in the market such as Trepn Profiler, Power Tutor, and Nokia Energy Profiler. These are applications which can display the real-time power consumption on a smartphone or tablet.
Interrupt Testing :-
An application, while functioning, may face several interruptions like incoming calls or network coverage outage and recovery. This can again be distinguished for:
Incoming and Outgoing SMS and MMS
Incoming and Outgoing calls
Incoming Notifications
Battery Removal
Cable Insertion and Removal for data transfer
Usability Testing :-
Usability testing evaluates the application based on the following three criteria for the target audience:
Efficiency: The accuracy and completeness with which specified users can achieve specified goals in a particular environment.
Effectiveness: The resources expended in relation to the accuracy and completeness of goals achieved.
Satisfaction: The comfort and acceptability of the work system to its users and other people affected by its use.
Installation Testing :-
Installation testing verifies that the installation process goes smoothly without the user having to face any difficulty.
Uninstallation Testing :-
The basics of uninstallation testing can be summarized in one line as “Uninstallation should sweep out data related to the App in just one go”.
Updates Testing :-
We need to be very much cautious about mobile app updates. People frequently complain about applications not working satisfactorily after an update. So it is very important that under the update testing, we qualify that the App will work as it was working previously.
In a nutshell, it should not break anything. Mobile application updates can take place in two ways – Automatic update and Manual update.
