Getting Started with XCUITest : UI Automation Framework on iOS

Automation testing on iOS applications has been highly standardized by Apple. Apps undergo rigorous checks before they have approval to seem on the App Store. They must abide by guidelines and strictly implemented regulation from Apple.

It is imperative that iOS developer build and maintain automation test cases to test apps that align with Apple ’ s regulations. They control that consecutive deployments of an app are working mulct and operate within the guidelines. To do this, developers must use XCUITest – a sub-framework within the XCTest Testing framework.

This article will discourse the role of automation, XCUITest itself, and how to get depart with it.

UI Automation Testing on iOS

UI Automation Testing is a relatively recent drill, and frameworks like XCUITest allow testers to develop light automation exam suites for an app ’ s UI.

1. Saving Time and Money

From the graph above, readers can infer how the apparently high initial investing of clip and resource for mechanisation earnings off over time. This metric can also be well extrapolated to. The UI is the main point of interaction and it ’ s critical that it act as ask.

2. Code Automation isn ’ t Enough

There is a good chance that a developer is using tertiary company frameworks like for testing code. One might likewise be wondering if UI examination is even required as they have been try their code.

The answer is YES. Developers absolutely postulate to perform UI testing. Code tryout instance check the behavior and to some extent, even the app ’ s interaction with other modules. However, developers do not have any metric on how each or new chassis impacts the UI functionality. The UI might occupy more than wait time to lade, or some changes might have rendered UI constituent non-functional. like Appium do not aid developer mechanically essay these scenario.

A previous clause on delves into the primary distinguishing feature that will help subscriber read why it is necessary to use both for.

3. iOS XCUITest and XCTest

If person tries to search for XCUITest, there is a good chance they might not chance it right away. The reason for this is that XCUITest is a part of the XCTest framework from Apple. However, it ’ s notwithstanding an sovereign module for try user interfaces, and in this article we will volunteer a beginner ’ s guide on how to use it.

Basics of XCUITest

, and more specifically, app UI testing involves checking how the interface behaves when user actions are execute and then equate results with expected outcomes. Here, testers try to double exactly how a user would interact with the application and validate the province of the UI. XCUITest allows them to write test cases for these purposes habituate two fundamental conception.

1. XCTest

As discourse earlier, XCTest is the base testing framework. It provides testers with the power to write test cases with both Objective-C and Swift. Testers can write UI test classes, method, and exam targets and do an assert to validate the behavior. Lastly, it is wholly integrated with Xcode.

Pro tip: Tools like SUSA can handle this autonomously — upload your app and get results without writing a single test script.

2. Accessibility

Using the Accessibility technology, QAs can also test and modify the app ’ s demeanor to check how it would perform when people with disabilities use the app. In this example, UI test event will use the part cater by the Accessibility core to execute and validate tests.

APIs for Writing UI Automation Test Cases

To test the UI, the fabric get with three special category that testers have to use while writing test cases.

1. XCUIApplication

Every clip examiner require an automated tryout to run, they need to set which app require to be launched as the first step. They want to create an instance of the XCUIApplication and call the launch method on it. This method is utilise to found the app before testing starts and also use to cease the app once testing is complete.

2. XCUIElement

The UI is create up of a set of independent UI components. The XCUIElement class of the XCUITest framework allows the test case to take control of any UI Element. This Class provides the methods to perform activeness on the UI component. These actions are similar to user interaction with the app & # 8211; tap, abstract, long insistency, or even rotating a component. It too allow testers to pilot the UI element hierarchy within the views.

3. XCUIElementQuery

To encounter a UI element (the XCUIElement) in the Interface, testers will be utilize the XCUIElementQuery methods. Once the application is launched and initialize, the context will pack all the information of the UI. This class will permit testers to search for a particular element on that UI and do some action on it.

Writing a Test Case habituate XCUITest Framework: Example

Let ’ s consider a sample test case and analyze its various components.

importation XCTest class SampleXCUITest: XCTestCase {override func setUp () {super.setUp () continueAfterFailure = false XCUIApplication () .launch ()} func checkText () {let appObj = XCUIApplication () appObj.otherElements.containing (.image, identifier: '' XCUITest Tutorial '') .element.tap () appObj.buttons [`` Learn More ''] .tap () XCTAssert (appObj.staticTexts [`` Automation Test iOS ''] .exists)}

This exam suite has one test event in it. It begins by creating a sample test class calledSampleXCUITest. Step 1 is to override the setup () which launches the iOS app.

The trial case here is ringcheckText ().Through this test lawsuit, the code is using the XCUITest fabric to perform the followers:

1. Find an image within the UI with an identifier called “XCUITest Tutorial” and so perform a tap action on it.
2. Next, notice a button on the UI with the text “Learn More” and perform another tap action on it.
3. Finally, see if the tap action leads to the text “Automation Test iOS” to appear on the UI.

When the test case is run, it action the trial described above and theXCTAssert methodwill formalise if the final schoolbook is visible. If it does, so the automated test pass. Else, it neglect.

Documenting Test Case Results

Running UI test cases is not just about bump out what succeeded or failed. As UI factor are involved, testers must be able to see what travel wrong, when it move improper and at what point in the codification the tryout lawsuit miscarry. The XCUITest model render multiple options to document these scenarios.

1. Screenshots

The XCUITest model cater a protocol called “ XCUIScreenshotProviding ”. This allows testers to capture a screenshot on an XCUIElement or an XCUIScreen target. This can be used when a test fails. The screenshot can be stored on file, and apply to document the bug leading to test failure. To capture a screenshot, call the screenshot () method on one of the instances cite above.

2. Recording

Image Source

The red button in the above image is the record push on Xcode. Upon pressing this option, Xcode will firstly hoard the test event and depart pass it on the type of device specified by the quizzer. Options include running tests on simulators or. The recording will show all the actions that were performed on the UI.

Wrapping Things Up

XCUITests as an is the iOS similitude to. It proves simple interface to write test cases that do any action on the UI and then document the activity as well as resolution.

Apple ’ s certification onUser Interface Testingwill offer more details on the classes and methods that examiner can use to automate UI testing for an iOS app. As witness earlier, the initial investment in terms of toll and clip might seem a bit high. However, over time, the ROI will become evident, making mechanization an essential part of every software development lifecycle. So, it is highly recommended to perform using XCUITest as the framework for iOS apps.

Frequently Asked Questions

1. What is XCUITest?

3. Is XCUITest open source?

No, XCUITest is not open rootage. It is a proprietary framework provided by Apple for essay iOS apps. It is included as piece of the Xcode development environment, which is exclusively usable for MacOS.

4. What is XCUITest driver?

The XCUITest driver is a element of the XCUITest framework that allows developers to automate the testing of their iOS apps. The driver provides an API that allow tests to interact with the app, simulating user interactions and verifying the app & # 8217; s behavior and user interface. The driver communicates with the Xcode development environment and the rudimentary iOS or tvOS operating scheme to action exam and homecoming solvent. The XCUITest driver is an essential part of the XCUITest framework and is utilize by developers to write and run automated tests for their iOS apps.
