Especially for mobile applications, automated testing has become a crucial step in the software development cycle. Automation of the testing process is now required due to the ever-increasing complexity of mobile applications in order to guarantee their quality and dependability. There are a number of technologies on the market for automated testing of iOS applications, including Appium and XCTest for User Interface (UI). Popular testing frameworks for iOS apps with distinctive features and functionalities include Appium and XCTest (UI). For developers and testers, choosing which one to employ might be a difficult process.
This blog highlights the comparison between Appium and XCTest (UI) and helps you choose the right tool for your iOS app testing needs. The blog also details the features, pros, and cons of each framework and provides insights into which one is best suited for different types of iOS app testing scenarios.
Major Advantages of Appium
- Cross-Platform Support: Appium is used to test apps across a variety of devices without the requirement for separate test cases for each platform because it supports both the Android and iOS operating systems.
- Open-Source: As an open-source framework, Appium is available for usage and modification by anybody. This also implies that a sizable developer community is supporting, enhancing, and contributing to the framework.
- Test Automation: Mobile application testing can be automated using Appium, which can significantly reduce testing time and effort. For quicker and more frequent app releases, it can be connected with Continuous Integration and Continuous Delivery (CI/CD) pipelines.
- Language Support: Appium supports various programming languages, which enables developers to use the language they are most comfortable with.
- Native and Hybrid Apps: Appium is a flexible framework for testing mobile apps because it supports both native and hybrid apps.
Disadvantages of Appium
- Complexity: Appium setup and configuration can be challenging, especially for new users who do not have much experience with mobile development. Before beginning to develop test cases, a lot of dependencies and configurations need to be installed and set up.
- Limited Support for Device-Specific Features: All device-specific functionality, including fingerprint readers, facial recognition, and other technologies, are not supported by Appium because this framework aims to achieve black box testing. This can restrict the types of app tests that can be performed.
- Performance: Appium can occasionally be slow because it depends on user interface (UI) interactions to automate testing, especially when testing complicated apps with numerous screens.
- Maintenance: The maintenance of test cases might be difficult, just like with any testing framework. To keep up with changes in the software, test cases may need to be changed regularly, which can take time.
XCTest for User Interface
XCTest (UI) is a testing framework developed by Apple for testing user interfaces (UIs) of iOS, macOS, tvOS, and watchOS applications. With the help of XCTest (UI), testers can automate user interactions and check how the application responds to those interactions by interacting with UI elements like buttons, text fields, and tables using an API. XCTest (UI) utilizes the XCTest testing framework and operates on Apple's Xcode development environment. It gives testers access to device functions like the camera, accelerometer, and GPS, which can be useful in testing applications that depend on such features, and it enables them to build UI tests in Swift or Objective-C programming languages. Additionally, with the aid of XCTest (UI), testers can create tests that mimic user behaviors like clicking buttons, swiping through screens, and typing into fields. Additionally, they can utilize XCTest (UI) to check that the UI is showing accurate data, responding appropriately to user input, and effectively managing failures.
Major Advantages of XCTest (UI)
- Native support: Since XCTest (UI) is an iOS native framework, it is completely compatible with Apple's development tools and APIs. This enables a smooth experience and makes it simple to integrate XCTest (UI) into the development process.
- Accurate and reliable testing: The testing abilities of XCTest (UI) are renowned for their precision and dependability. It can test the entire application, including the user interface and user experience, and simulate user interactions.
- Powerful API: Developers can design and modify tests using the robust API offered by XCTest. With the help of this API, programmers can perform a variety of tasks, such as interacting with the user interface and asserting the app's status.
- Easy to set up: The built-in tools of Xcode can be used to configure XCTest (UI) easily. As a result, developers can instantly start using XCTest (UI) and testing their applications.

Disadvantages of XCTest (UI)
- Slow test execution: Execution times for XCTest (UI) might be lengthy, especially in comparison to other testing frameworks. This is due to the lengthy setup and teardown times needed for each test.
- Limited cross-platform support: Applications for iOS, macOS, tvOS, and watchOS can only be tested with XCTest (UI). As a result, it cannot be used to test software on other operating systems, such as Android or Windows.
- Lack of flexibility: When it comes to testing an app's non-UI components, XCTest (UI) can be rigid. For instance, using XCTest (UI) could make it challenging to test server-side logic or background activities.
- Limited device support: XCTest (UI) is only capable of testing software on iOS 9.0 or later-running devices. This implies that XCTest (UI) may not be able to test older devices.
- Xcode version dependencies: In most cases, XCTest (UI) code is maintained in the same project as the target application. Upgrading Xcode could introduce breaking changes for swift programming language and dependent APIs. The situation could cause difficulties in updating the target application first, then the test code to keep correct each other. It means testers should update both at the same time. It could cause difficulties in detecting which is wrong if both or either environment has issues.
