Here’s how to test iOS applications through different cases and life cycle stages 10 different ways

In this article, I will talk about life cycle and iPhone and iPad applications. But wait – why should you care? Let me explain:

By understanding how the application moves through countries, you can capture infiltrated errors and simulate the real world scenarios and make sure everything works smoothly-even when the application does something in the background.

What is the life cycle and application situations?

Imagine that your application is similar to the person who passes through different parts of his day. Every part of their day is a state, and the transformations between these States The life cycle is formed. Here is how to work:

Active

When the application is actively used by the user (for example, moving via screens, interacting with the interface, or receiving updates in actual time), it is in the active state. This is the regular operating status of the application.

Background

When you switch the focus to the second application, this app becomes active. However, if the app that you have just used has tasks are formed to run in the background (such as data download or site tracking), it will continue to run these tasks although they are active user actively. We say that the application is now in Background.

To simulate the background status, raise the application up or switch to another application by switching the application. The application will be sent to the background and may perform tasks such as downloading content, synchronizing data, or listening to payment notifications.

The suspended country

The application is transmitted to hanging When sending it to the background and do not actively perform any tasks such as background downloads or updates.

in hanging The case, the application does not consume resources but is still in the background until the system or user ends.

If you switch quickly from your application and return to it, it may seem to be re -downloaded or updated as if it was hanging. Usually, applications in the suspended state do not perform any active tasks or use resources.

Inactive

If you are using the application actively and receive an incoming call or an alert, the application may be briefly entered Inactive state. Once the interruption is over and the focus is back to the application, it is again in the active state.

Don’t work

If you pass the application up and close the application, the application is no longer in operation. In some cases, the application’s operating system will allow the background tasks to run for a few seconds before it is completely terminated, if these tasks are important.

You can select the application Don’t work If you try to open it and release it from the zero point, showing the application screen.

Test through the application life course: Tips and tricks

When you test iOS, it is important to make sure to behave properly across various cases. For example:

• If the app is not running, you need to check how it is dealt with with the cold, making sure to download data and user interface without delay.
• While the application is in the background, you must check that it is doing custom tasks (such as refreshing content or processing processes) within the limits of iOS resources.
• You should also check the transformations between cases to ensure smooth dealing without defects, delays or data loss.
• Finally, you should test interruptions and make sure that the app has an appropriate response.

Here are some test scenarios that you may find useful:

The application was suspended on continuous tasks

What was tested: How the application deals with long -term tasks such as downloading files or data processing when suspended.

Why is this difficult: IOS freezes the application in a state of suspended implementation, but some tasks such as rear downloads may still need to follow up. If it is not managed correctly, the application may lose data or fail to complete the tasks.

How to test it:

1. Start a long -term task like downloading the file.
2. Put the app in the background and leave it for a long time (several minutes to hours). You can do this by opening another application and using it for a short period.
3. Check whether the task that started in step 1 successfully ends with just resuming or reopening the application.
4. Check that the application does not fail or lose progress due to the comment.

The application is terminated by the system while it is in the background

What was tested: How the application behaves when it is completed by the system due to low resources (memory or battery).

Why is this difficult: IOS may force a take off if the system needs resources. This can happen while the application is in the background, and applications may need to deal with restoring the situation or continuing data when re -launch.

How to test it:

1. Put the app in the background and start a dense memory task such as heavy data processing or video flow.
2. Memory warning simulation or application power by switching the application.
3. Restart the application and verify whether to properly restore user, session and case data.
4. Check if there is any data loss or breakdown when reopening it.

The application is placed in the background while inserting the user

What was tested: How to deal with the insertion of the user or typical introductions during which the application is sent to the background.

Why is this difficult: If the application is transmitted to the background while inserting the user actively, the application must properly save the data to avoid loss. The app may also need to deal with incomplete tasks such as sending models when returning to the foreground.

How to test it:

1. Start entering data in a model or text field.
2. Transfer the application to the background (for example, press the home page button).
3. Return to the application and check if the form of the form or the field is properly saved.
4. Ensure that the user does not present with an incomplete form or an error message when returning to the application.

Payment notifications received during the suspension case

What was tested: How the application deals with notifications when suspended or not operating actively.

Why is this difficult: The notifications can be received while hanging the application or not running at all. The application must deal with these notifications appropriately by either by showing an alert, updating the user interface when returning to the foreground, or performing the background tasks (if allowed).

How to test it:

1. Application suspension (let it work in the background for a long time).
2. Send the payment notification while the application is in the suspended case.
3. When resuming the application, check how to process the notification:
   • Do you update the user interface properly?
   • Do you display the correct screen?
   • Is there any delay or notification?

Network changes occur during case transfers

What was tested: How the application deals with the network connection (such as the change from Wi-Fi to cellular data or the full network separation) while moving between different application cases (active, background, hanging).

Why is this difficult: Network changes can be disrupted tasks such as data synchronization or download, especially during the transitions of the case. The application should be managed efficiently download, download cases, and error processing.

How to test it:

1. Start a network -dependent task such as downloading content or data sync.
2. Switch from Wi-Fi to cellular data or completely disable the network while moving the condition (such as moving from the background to the suspended condition).
3. Check that the application deals with the change properly:
   • Are you to try to ask or show a mistake?
   • Has the task resumed correctly when regaining the network connection?

User default or session data processing after comment

What was tested: How the application deals with saving the session data and restoring it (such as the user’s entry, preferences, etc.) when hanging the application and then resumes.

Why is this difficult: If the application does not keep user data properly when suspended, users may lose their place in a flow or have to log in again when reopening the application. This can cause frustration and poor user experience.

How to test it:

1. Make changes on user data (for example, change the preferences or log in).
2. Put the app in the background and leave it there for a period of time.
3. Return to the application and verify the data preservation and the user has not been registered or forced to re -enter the information.

Multiple counterparts from the application once

What was tested: How the application behaves when multiple counterparts are operated simultaneously (for example, log in to two different devices), and whether the state’s conflicts arise.

Why is this difficult: Some applications may not deal with multiple sessions properly, which leads to data or errors when the user turns between devices or application counterparts.

How to test it:

1. Open the app on two devices or in windows (for example, open the app on the iPhone and then on the iPad).
2. Conducting procedures that modify the user data or the status of the session on the first device.
3. Switch to the second device and verify whether the changes are reflected properly or if any conflicts appear.

The use of the application has been boycotted through an event on the device

What was tested: How the application behaves when boycotting incoming calls, text messages or notifications.

Why is this difficult: The application must ensure that the user’s progress is saved and it must resume smoothly after the interruption. Proper treatment for interruptions improves the total user experience and prevents data loss.

How to test it:

Switching between applications (multiple tasks)

What was tested: How the application behaves when users switch between applications.

Why is this difficult: IOS allows a quick switch between applications, so make sure that your application maintains its condition when returning is very important to share the user.

How to test it:

• Switch the application

  1. Open the app, then switch to another application.
  2. Return to the original application and verify the last restoration of the last case. If the user is on a specific screen, they should see that fine screen.

• Preserving the state

  1. Go on multiple screens in the application.
  2. Switch to another application and return to the original application.
  3. Check that the mobility staple is sound, and the user can return to the previously displayed screens without losing data or condition.

Task processing while running the application in the background

What was tested: How the application deals with background tasks such as downloading or synchronizing data while the application is in the background.

Why is this difficult: You must make sure that the background tasks are continuing efficiently and the user receives time updates without depleting the resources of the device.

How to test it:

• Download the background

  1. Start the task of downloading in the application.
  2. Switch to another application and leave the download in the background.
  3. Return to the application and make sure to display the download of the download.

• Data synchronization

  1. Start the data synchronization in the background.
  2. Switch to another application and return to the original application.
  3. Make sure to finish synchronization and that the updated content is visible without having a manual update.

For conclusion

We have talked about iOS application cases and we explored some of the main cases that may affect the application and performance functions. The use of these situations in a mobile phone test routine can help you prevent data loss, disruption and unexpected behavior.
