iOS app test overview
1. Apps on iOS platform
iOS is the Mobile Operating System, designed for Apple devices.
According to current research, iOS is the second most popular mobile operating system on the market. iOS is limited to Apple hardware and doesn't have many platforms like Android. iOS has had a total of 10 major releases over the years, each release offering great feature updates.
This iOS operating system is easy to use, flexible to operate, and there is no problem with apps.
The Apple iTunes App Store for iOS is extremely rich with up to 2.2 million applications. The number of app downloads has rapidly reached 130 billion.
IOS is an operating system that is not restricted by regional or language barriers. So it's one of the main factors that made this operating system famous in just 10 years of development (and it supports 40 different languages.)
2. General issues of iOS apps
2.1 Error that the app does not respond
One of the biggest problems with using apps on Apple devices is that apps can crash frequently.
An application may crash when performing certain actions or because the application's memory is compromised.
2.2 Incompatible apps
The iOS app can run fully on the current iOS version. However, when the iOS version is updated, the app may not work as it does not yet support the new version. It was a bug under development that did not detect this issue and was causing an incompatibility error.
2.3 Security error
A security flaw in iOS allows hackers to attack iOS devices and steal your personal information. To date, many serious iPhone security vulnerabilities have been discovered in different versions of iOS.
2.4 Memory leak error
Memory leakage is the amount of memory allocated to an application when it is no longer in use. A memory leak causes the iOS app to crash, which is a very serious error.
2.5 Installation issues
You may have problems during the iOS installation. You may need to reboot your device frequently for ease of use.
2.6 Low backup battery
Many users are dissatisfied with the short battery life of iOS 8.3. The backup battery turns off while the device is in use.
It could be an iOS issue, not a battery issue. It may be an iOS error that the battery is draining more and more.

MindMap iOS shows you all the items that testers need to consider when testing on iOS.
- Interface: Considering the operation, effect, and ease of use of the application of the animation, you need to confirm the operation when rotating the screen of the device.
- Hardware: You need to consider applications on different types of iOS devices such as iPhone, iPad, iPod. (Depends on application requirements.)
- Features: You need to consider important features of the device to which your application is associated, such as email, services, the web, and phone.
- Software: You need to consider common and important errors that occur frequently, such as application crashes, memory leaks, and security errors.
3. iOS Application Testing Checklist
This Checklist is designed to test the characteristics of iOS mobile applications. This Checklist only supports the general features of iOS applications and does not describe each feature.
- Check the time set on the device. Make sure the application is installed in a reasonable amount of time.
- After installing the application, check if the application icon and application name are displayed on the device screen.
- Launch the application and see if you see the splash screen.
- Check how long the splash screen is displayed and how long it takes to load the main screen. The home screen of the app should load within an acceptable time.
- Check if your app supports both landscape and portrait orientation. If so, test your app in both directions to make sure the human interface is well designed.
- Open the application when you are not connected to the internet. Make sure the application works as needed. In this case, the application may hang or display a blank screen.
- If your app uses the location feature, check to see if you see a location permission warning. This message is displayed to the user only once.
- If your app sends push notifications, check to see if the notifications are displayed.
- Start the application, exit the application, and start it again. Check if the application is working as needed.
- Press the home button on your device to close the app and reopen it. Check if the application is working as needed.
- Once installed, check if the app is listed in the iPhone Settings app.
- Once your app is released, check to see if you can find it on the App Store. There are OS versions supported by the app. So make sure you can find the app in the App Store for devices with supported OS versions. In addition, the app was not found in the App Store for devices with unsupported operating systems.
- To avoid draining the battery, check if the app goes to sleep when running in the background.
- If your application is slow or something is loaded, check for a progress icon (the "loading" icon) or if there should be a specific message.
4. Notes on testing iOS apps
To test your iOS app in the right direction, you can implement the following considerations:
4.1. Do not test with emulator
The emulator is not an ideal environment for testing. Issues such as user interaction, battery consumption, network availability, usage performance, and memory allocation cannot be tested with the emulator. Now let's test it on a real device.
4.2. Automation, not manual
How to get the job done quickly? Consider automation. Automation not only reduces execution time, but also improves the effectiveness, efficiency, and scope of software testing.
4.3. Sharing work
Share issues that arise during testing with other teams and development teams to help you run test cases manually or get help from team development on automating manual test cases.
4.4. Identifying Crash Logs
Apps for iOS may freeze or crash under certain circumstances.
For troubleshooting purposes, use a tool that can read the Crash Logs to determine the exact location that caused the error.
4.5. Screen capture
Saving the screen where the error occurred makes it easier to understand the problem and fix it.
We recommend that you save the screen or take a screenshot of the problem so that the development team can better understand the problem. You can take a screenshot using the built-in features by pressing the power button and home button at the same time.
The above are some things to keep in mind when running iOS tests. It's important to be able to successfully test your iOS application by choosing the right method, testing process, tools, and the right device.
