All You Need To Know About Test Automation in iOS App Testing

iOS automation testing involves the examination of applications that exclusively function on iOS devices. Generally, app testing requires comprehension of the app’s purpose, technical prerequisites, and performance measures to compare anticipated behavior with the actual outcome. The iOS operating system runs on a closed environment limited to Apple devices. Consequently, testing programs on a diverse range of devices is simpler compared to Android apps, which can be installed on a significantly larger number of devices.


Personal testing of the iOS app is necessary, along with the utilization of automation tools. Regardless of the level of design, bugs are inevitable in any application. Hence, automated testing for iOS holds equal importance to testing software on any platform, be it iOS or Android. To ensure quality, the activities related to quality assurance should commence at the outset of the application lifecycle. Testing iOS applications on these devices proves more convenient due to their familiarity and well-planned OS updates. Automated testing for iOS apps offers numerous advantages, such as time and effort savings through the execution of a single test script simultaneously on multiple devices.

What is iOS App Testing?

iOS App Testing involves the evaluation of an iOS application on real Apple devices to verify its proper functioning in relation to specific user actions. These actions include installation, user interface, user experience, appearance, behavior, functionality, load time, performance, App Store listing, OS version support, and more. The purpose of this testing process is to ensure that the application meets the expected standards and performs as intended on iOS devices.

Types of iOS Application Testing

Following are the many forms of iOS app testing online that can be performed under normal circumstances:

  • Manual Testing – Using Device
    • System Testing
    • UI/UX Testing
    • Security Testing
    • Field Testing
  • Automation Testing
    • Regression Testing
    • BVT Testing
    • Compatibility Testing
    • Performance Testing

iOS Automation

a) Regression Testing:

Changes are constantly made to the programme to improve it or to address problems that were discovered in a prior version of it in the constantly shifting environment. There is a potential that the modifications made to the programme during implementation will modify the functionality already there.

Simply put, the modifications made might cause the programme to experience a new set of problems. Regression testing must be done to make sure that the application still functions as intended even after the modifications are made. Automation is useful for this type of test run because it is a repeated task.

b) BVT Testing:

It is a smart practice to run an automated suite on the new version that has been made available for testing because it saves a lot of time and alerts you right away if any fundamental features break. The results of automated basic verification tests to approve or reject a build can be obtained in minutes as opposed to a manual effort.

c) Compatibility Testing:

As mentioned already, Apple releases a wide variety of products. There are various iPad versions, iPad Pro models, iPod Touch models, and different types of iPhones available in the market.

Now, when an app like ours is built, all the devices should support it. That suggests one thing: All test cases must be executed on all these devices.

Now that there are so many machines, physical labour is not an option. Automation testing is preferable for compatibility.

d) Performance Testing:

Understanding how the app behaves when it is put into operation or operates for a very long period are some of the things that are checked during performance testing.

  • Make the application engage, communicate, or do nothing while it is operational.
  • The same procedure must be carried out repeatedly with varying weights.
  • The way the system responds to extremely large data transfers.

Most of these recurrent instances are handled by automation.

iOS Application Testing Checklist: Things to Consider

An extensive analysis of many components is required while testing iOS applications. Functionality, compatibility, usability, performance, and security are just a few of them. To ensure the quality of the application, testers must take all these factors into account.

Native functionality:

One notable distinction between a web app and a mobile application lies in the ability of the latter to leverage native features of mobile devices. Users expect these native features, such as gyro sensors or multi-touch, to function accurately. Therefore, it is crucial to thoroughly test your application to ensure the proper implementation of these native capabilities.

CDNs and third-party services:

Another critical aspect to consider during iOS app testing online is the accuracy of CDNs and third-party services. For example, if your iOS app incorporates maps from a third-party provider, it is important to validate that the requested and displayed location aligns correctly.

Performance metrics assessment:

Evaluating performance metrics allows you to gain insights into how your iOS app performs across various parameters. This includes analyzing network performance, assessing the efficiency of function calls, and more. These metrics enable you to optimize your application in a positive direction.

User Interface and User Experience (UI/UX):

The visual appearance and user experience of the app are paramount to its success. It should be user-friendly, visually appealing, and accessible to users with varying levels of technical expertise and devices. The app should facilitate easy navigation and quick access to desired content without the need for extensive searching through menus or tabs. Additionally, its features should be intuitive, easy to understand, and readily customizable based on user preferences. Lastly, the app should allow seamless transition between screens or functions without requiring users to start over each time.


Testing an iOS application may be quite difficult. Through this post, hopefully you have a solid grasp of iOS application testing. However, successful iOS application testing depends on choosing the correct methodology, testing procedure, tools, and devices, among other factors.
