Tips for optimizing your iOS mobile app testing
Mobile app testing for iOS is an essential part of any development process due to high competition in the market nowadays. In this article, we’ll provide 5 practical tips to optimize the testing process to make it more efficient.

Tip 1. Where to Start: Performance iOS Mobile Application Testing

Performance testing is an automated testing for iOS, which simulates the operation of a particular number of users of a shared resource.

Primary goals:

  1. Determine the number of users who can simultaneously work with the application.
  2. Check the behavior of the application with increasing intensity while performing any operations.
  3. Check the behavior of the application when using it for many hours on the average load.
  4. Check the behavior of the application in stress conditions.
  5. Check the operation in a "growing" database, how quickly the queries are executed.

The main purpose of this type of testing is to make sure that the application work is acceptable under certain performance requirements: access to a large number of users, the elimination of an important infrastructure element, such as a database server, and others.

Tip 2. Use this Performance Test Scenario for Mobile Applications

  1. 1. Determine whether the application works the same way in different environments of the network load.
  2. Determine whether the current network can provide the application work at various levels of user load.
  3. Find out whether the existing client-server configuration provides optimal performance.
  4. Find application and infrastructure bottlenecks that reduce the performance of the application.
  5. Check whether the response time meets the requirements of the application.
  6. Rate the product and/or hardware ability to cope with the planned load volumes.
  7. Estimate the time during which the battery can maintain the application working in the conditions of the scheduled load volumes.
  8. Check for disruption when going from the Wi-Fi-network to mobile 2G/3G network and vice versa.
  9. Check that each of the processor memory levels works ok.
  10. Make sure that the battery consumption and memory leak do not go beyond the norm, and the work of various resources and services, such as GPS-navigation or the camera meets the requirements.
  11. Check the stability of the application under high user load.
  12. Check the efficiency of the network in the conditions when the device is in motion.
  13. Check the performance of the application, if it works in a non-permanent connection to the Internet.

Tip 3. Mobile App Testing: Improve Security

This testing strategy is used to check the safety of the system, as well as to analyze the risks associated with providing a holistic approach to the protection of applications from hackers, viruses, unauthorized access to confidential data. The primary purpose of this type of testing is to ensure network security and software data.

Here are the key steps to check the security of mobile applications.

  1. Make sure that the user data such as usernames, passwords, credit card numbers are protected from network attacks by automated systems.
  2. Ensure that the application does not provide access to the private content or functionality without proper authentication.
  3. Make sure that the system application security requires a strong password and does not allow an attacker to take over other user passwords.
  4. Make sure that the session timeout is adequate for the application.
  5. Find dynamic dependencies and protect these sensitive areas from burglars.
  6. Protect the application from SQL-injection type of attacks.
  7. Protect the application and the network from DoS attacks.
  8. Analyze the data storage and verification requirements.
  9. Provide session management to protect information from unauthorized users.
  10. Check all cryptographic codes and, if necessary, correct the errors.
  11. Ensure that the business logic is protected and not exposed to attacks from outside.
  12. Analyze the interaction of the system files, identify and correct vulnerabilities.
  13. Check protocol handlers (e.g., Do not try to reconfigure the default landing page by using malicious iframes).
  14. Protect applications from malicious attacks of customers.
  15. Provide regular data security control.
  16. Examine the user files and prevent their possible harmful effects.
  17. Secure the system against buffer overflow cases or violating the integrity of the information in memory.
  18. Make the analysis of the different data streams and protect against their possible harmful effects.

Tip 4. Improve your Mobile App: Testing iOS Usability

Usability testing is carried out to create a quick and easy iOS applications. The main purpose is to provide ease of use, an intuitive interface corresponding to the accepted standards.

So, take the following steps for mobile testing on iOS app:

  1. Make sure that the buttons have a normal size and are suitable for large fingers.
  2. Put buttons in one area of ​​the screen, so as not to cause confusion among users.
  3. Make sure that the icons and images look natural in the application environment.
  4. Make sure that the color of the buttons that perform the same function is the same.
  5. Ensure minimum keyboard input.
  6. Ensure you have the possibility of returning or canceling the operation if you press the wrong button.
  7. Make sure that the contextual menu is not overloaded.
  8. Make sure that the text is simple, clear and visible for the user.
  9. Make sure that the short sentences and paragraphs can be read.
  10. Find the optimal font size.
  11. Make sure that you can close the application from any state and it resumes in the same state.
  12. Check that all the lines are displayed in the desired language, if the application has a localization option.
  13. Make sure that the components of an application are synchronized with the user's actions.
  14. Provide user management, which would help him to understand application performance and actually use it.

Tip 5: Select the Best Tools for Testing

What is the best tool for testing iOS apps? Should it be free or expensive? What should it offer for you? The answer is simple. Use several tools to make your application the best. Here are the tools:

  • iOS 6-10. Yes, you will need to have a device with the versions of iOS starting from 6 and to the latest one. Otherwise, your success might fail.
  • xCode. It’s a tool provided by apple. It can give you lots of its functions to cover all the above mentioned types of testing.
  • Fiddler 4. It allows you to create HTTP-requests and view the response using the REST API Azure search without having to write any code.
  • iPhone Configuration Utility. Use it to configure, install and maintain configuration profiles.
  • Testflight. It’s a great tool for beta testing of your app.
  • Crashlytics. This tool is also used for beta testing of your apps.
  • Calabash. Tool for automation functional UI testing.
  • Appium. Tool for automation functional UI testing.
