Mobile Functional Testing means testing the functions of mobile applications, such as user interactions and transactions. Functional testing is performed by mobile application developers to ensure application quality, meet user expectations, and reduce the risk of errors in mobile applications. The most common scenarios in functional testing include: 

• Verify that all required MANDATORY fields WORK as intended.
• Every time an application starts/stops, make sure the application works correctly.
• If the app is running, check whether SMS can be stored, processed, and received.
• Check if the device can perform multitasking functions when necessary while the application is running.
• Verify that the application provides access to social network features, such as sharing, posting, and NAVIGATION.
• Check that the application is CONFIGURED to support the PAGE scrolling scenarios.
• Verify that navigation between relevant modules is in accordance with the requirements.
• Check to ensure that the user receives an appropriate error message, such as "Network error".
• Ensure that the installed application does not consume the memory of other applications and that it enables other applications to perform satisfactorily.
• If the system crashes or the application crashes, verify that it resumes from the last operation.
• Ensure that the user has access to the required resources to install the application smoothly and that it will not lead to significant errors.
• Testing the performance of the application in all versions of Mobile, including 2G, 3G, and 4G.
