Different types of mobile application testing include:  

• Functional Testing: The test determines whether an application is functioning correctly. It aims to ensure that the app's functionality works as expected not like the user interactions as well as transactions that users might perform. It is a type of black-box testing.
• Usability Testing: This type of testing EVALUATES how intuitive and easy an application is to use, and identifies any bugs to improve the user experience.
• Compatibility Testing: The test determines whether an application whether the application is compatible with different OS (Operating Systems), different network environments, as well as with specific hardware specifications.
• Performance Testing: During this testing, an application is EVALUATED on how well it performs and behaves under various loads.  In this test, the application is continuously and steadily LOADED until it reaches a threshold point (a point beyond which the application cannot withstand the load).
• Installation Testing: Applications undergo this test to ensure that they are properly downloaded, installed, and uninstalled, as well as new updates are handled smoothly.
• Security Testing: Application behaviour under various device PERMISSION requests is examined during the test, while the user's data PRIVACY is prioritized.
• Storage Testing: Applications are tested on how well they handle storage-related functions and how they behave when there is no or little memory on the device.
