3. Security Vulnerabilities

In the realm of mobile app development, prioritizing security is paramount. With the exponential growth in the volume of data stored on app servers and the increasing power of mobile devices, the risk of data breaches has become a significant concern. Hackers employ intricate methods to exploit vulnerabilities and pilfer crucial data in transit. Unsecured protocols or compromised mobile devices pose potential access points for unauthorized intrusion. Therefore, it is essential to have comprehensive mobile app security testing in place, regardless of whether you are developing a new app, testing an existing one, or designing your mobile strategy. Security testing also checks for common security flaws like cross-site scripting (XSS) and SQL injection. By conducting thorough security testing, app developers can identify and mitigate security risks, safeguard user data, and provide a secure user experience, instilling trust and confidence in their applications. This also includes encryption of locally stored data on the device, secure storage of confidential information, thorough testing of biometric unlocking options such as fingerprint or Face ID, and evaluation of the effectiveness of Two-factor Authentication (2FA) mechanisms.

4. Network Performance

To comprehensively evaluate the performance of your application in different network scenarios, it is essential to conduct tests under various network settings, including situations with poor signal strength and during data transfer. During these tests, several key factors should be considered to accurately assess the network performance:

• Jitters- Data collection delays can lead to packet scattering during transmission, causing the data to become scrambled, a phenomenon commonly referred to as jitters. In such instances, it is crucial for the application to proactively prompt the user, offering the option to either resend the data or patiently await the system’s response.
• Packet Loss- In the event of complete packet loss, it is imperative for the application to take appropriate action such as resending the data request or promptly notifying the end user. Instead of subjecting the user to an extended waiting period, the app should proactively prompt them to retry the operation.
• Network Speed and Type- To ensure a seamless user experience, it is essential to account for the variability of network speeds. Thoroughly testing the application across different networks and varying speeds can provide valuable insights into its behaviour.
