Creating comprehensive security measures can be difficult since performing security testing requires specialized knowledge and tools.

Varying network conditions: Mobile app that cannot function at low internet speeds, is less likely to be used. Mobile apps are often used in varying network conditions, because everyone does not have access to high-speed internet every time and everywhere. Testing the app under different network conditions like slow internet speeds, and dropped connections can pose challenges. However, is necessary to ensure the app remains functional in real-world scenarios.

Unpredictable user environment: In the real world, there are a million things that can cause apps to fail in one aspect or another. This is because mobile users interact with apps in diverse environments and contexts. For example, a call can come in, battery power may get very low, the phone may restart or shut down during the app’s running, and the user may leave the app running and turn to something else.

Simulating the app for every possible environment and user scenario that exactly replicates the real-world settings in which the app will be used can be difficult.

Battery and Resource Consumption: Extensive performance testing is required to optimize mobile apps and identify issues related to excessive battery usage, resource consumption, or background processes.

Limited testing period: In the rapid pace of app development, testers often get limited time for thorough testing, resulting in missed bugs or incomplete test coverage, especially in large-scale or complex apps.
