Even when you separate business logic code from your SwiftUI views the previews and also view bodies seems both to count for the unit test code coverage. I read many articles in the internet about how to test SwiftUI code and archive good code coverage. But they all seem not to be the perfect solution for this task. Is there any good guide for unit and ui testing SwiftUI code that Apple recommends for their apps?

Hi, I'm currently researching if we are able to migrate to Xcode Cloud in our project. I encountered one issue. I run unit tests on Xcode Cloud and I see that they finish in ~150 seconds, but the whole step takes ~530s and there is no information in logs why. I even run the same command on my local computer and it doesn't take that long. Any ideas? Any way to optimize it? Also one more thing: it looks like Xcode Cloud is not running on M1 machines. Do you know guys if there are plans for Xcode Cloud to take advantage of M1/M2?

Are there commands for testing watch complications in XCUITest? So far I see that we can press the home button and rotate the Digital Crown in test As of Xcode Version 14.0 beta (14A5228q) the XCUITest record function doesn't work. Can't find anything in debugDescription to helpout either with reaching complications https://developer.apple.com/documentation/xctest/xcuidevice/button

Underlying Error: The request to open "org.example.m.beta" failed. (Underlying Error: The operation couldn’t be completed. Application info provider (FBSLazyApplicationInfoProvider) returned nil for "org.example.beta"

We are trying to build tooling around UI tests. We'd like to get a list of all of the UI tests in our project. Does anyone know how to do this on the command line using xcodebuild or some other command line tool?Also, do you know if it's possible to ask xcodebuild to only run specific tests via the command line some how?

As far as I understand the typeText Function simply copies the value from Test script to the textbox. Is there a function that actually types ( Keyboard input ) to a textbox? I have been through multiple Apple Dev forums and Stack-overflow but was not able to find an answer, could you please guide me on the same?

I am trying to write a UI test for our app's IAP using a sandbox account. However, when trying to tap this purchase button, the test is unable to find this element: I've tried targeting this element by its button name and label name with no success. During the UI recording, when tapping this button, Xcode freezes completely and I am forced to shut Xcode down. I've also tried debugging at this step and when I print out "app.debugDescription" in the console, this button nor any of the other elements in this purchase drawer is returned. Failing line of code: app.buttons["Purchase"].tap() Error message: No matches found for Elements matching predicate '"Purchase" IN identifiers' Xcode Version: 13.2.1 iOS Version tested (real iPhone device): 15.3.1

In my XCUITest tests, I expected to be able to scroll elements in iOS >= 15 devices (with X,Y deltas) since it’s declared in the header file as: /** * Scroll the view the specified pixels, x and y. */ @available(iOS 15.0, *) open func scroll(byDeltaX deltaX: CGFloat, deltaY: CGFloat) However, in the documentation website (https://developer.apple.com/documentation/xctest/xcuielement/1500758-scroll) it says under “Discussion”: Available in macOS and in iPadOS 15 and later. No iPhones :( Although it says nothing under “Availability”. Calling this action when running on iPhone simulator, indeed raises the error message: Pointer events are not supported for this device. I’d expect this action to work on iOS as well, and not only on iPadOS. But sadly, as I mentioned, it isn't. I made some workaround to make this "work" (partially), using XCUICoordinate but I really don't like it (since it's impossible to find an hittable coordinate without guessing or using some messy heuristics that includes frames work) and would have been happy for something more elegant. Is there any reasonable (elegant and accurate) alternative for this, that is scrolls based on X and Y deltas?

Hello, Did anyone succeed to chose a specific Configuration from the Test Plan to be used for running tests using Test Plans on a Xcode Bot? I tried multiple possibilities with no success. We can pass to xcodebuild the following parameter and it will run the desired test plan "test -testPlan NameOfTheTestPlan", but if there is only one configuration under the test plan , all the tests will run twice because of the default "Share Configurations" Any ideas? Thanks!

I'd like to use the new localization screenshots and test plans feature to take screenshots in different languages, for the app store. I end up with images that are half one screen and half another, like it's some kind of timing issue. My test code is below. Is it missing something that would give it the right timing on the screenshots?I wrote a UI test and set "Localization Screenshots" to "On" in the test plan's settings. The UI test walks through a few screens and the resulting test report has a few image files attached labeled "Localization screenshot". Some images are are split so that the left side is one view controller and the right side is another, like it captured a push navigation transition. Another image has two overlaid screens, each half faded.I'm running in the simulator. My test code looks like: func testTakeScreenshots() { let app = XCUIApplication() app.launch() // At workouts page app.tables["workouts"].cells.element(boundBy: 0).tap() // At first workout app.navigationBars.buttons["edit"].tap() // At workout edit screen, click first exercise app.tables.cells.element(boundBy: 0).tap() ... }

I have a SwiftUI menu Menu{ .... }, label : { Image(...).accessibility(identifier: "cardMenu") } I used to be able to bring up the menu (before upgrading to xcode 13 (ios15)) like this let app = XCUIApplication() app.launch() app.buttons["cardMenu"].tap() But now i am unable to see the identifier in app.buttons. Can't seem to find the identifier anymore. I've tried looking for the identifier in the other app fields and changing to use text instead of identifer. No luck. These tests used to work prior to the upgrade. Any help would be appreciated

In MacOS I can achieve this via func sendKeyStrike(_ keyCode: CGKeyCode, useCommandFlag: Bool) { let sourceRef = CGEventSource(stateID: .combinedSessionState) if sourceRef == nil { NSLog("FakeKey: No event source") return } let keyDownEvent = CGEvent(keyboardEventSource: sourceRef, virtualKey: keyCode, keyDown: true) if useCommandFlag { keyDownEvent?.flags = .maskCommand } let keyUpEvent = CGEvent(keyboardEventSource: sourceRef, virtualKey: keyCode, keyDown: false) keyDownEvent?.post(tap: .cghidEventTap) keyUpEvent?.post(tap: .cghidEventTap) } Is there a function call either in XCUITest or any other framework to achieve keyboard strokes in IOS? IOS Seems to have HID keycodes but I just can't find a way to send them to the device. Either through XCUITest or any other framework. (I am ok with simulating a HID device using python or something else to command my iOS device as well.

I want to test app launch performance in my project. Therefore I tried to use performance test with measure func and XCTApplicationLaunchMetric. But after test completion there is no any result with average time. Here is a test example: func testLaunchPerformance() throws {         if #available(macOS 10.15, iOS 13.0, tvOS 13.0, watchOS 7.0, *) {             // This measures how long it takes to launch your application.             measure(metrics: [XCTApplicationLaunchMetric()]) {                 XCUIApplication().launch()             }         }     } But when I create a new empty project and add the same performance test – it works and shows app launch results. 1st image is a real project test – there is no test result. and the 2nd image is a demo empty project test – it has performance result diagram. I am running test on MacBook with M1 Pro chip. However, when my colleague is running the same performance test on our real project with Intel based MacBook Pro – all is fine, it shows app launch results correctly as my demo project. I have no idea how it can be fixed, because it seems that it depends on M1 chip 🤷🏻‍♂️. May be somebody have a solution?

Hey people, I recently switched to a macbook pro M1 from an intel one, and I'm not able to run unit tests on the M1, it builds, but as soon as it runs it just pauses as you can see in the screenshot and if I try to continue the execution it just keeps stopping there. I also tried creating a new test target on the M1 laptop but when I execute it the same things happens. backtrace:  * frame #0: 0x0000000204a6145e dyld`__shared_region_check_np + 10   frame #1: 0x0000000204a3b2e4 dyld`dyld3::reuseExistingCache(dyld3::SharedCacheOptions const&, dyld3::SharedCacheLoadInfo*) + 30   frame #2: 0x0000000204a3b241 dyld`dyld3::loadDyldCache(dyld3::SharedCacheOptions const&, dyld3::SharedCacheLoadInfo*) + 1857   frame #3: 0x0000000204a39156 dyld`dyld4::SyscallDelegate::getDyldCache(dyld3::SharedCacheOptions const&, dyld3::SharedCacheLoadInfo&) const + 58   frame #4: 0x0000000204a2325f dyld`dyld4::ProcessConfig::DyldCache::DyldCache(dyld4::ProcessConfig::Process&, dyld4::ProcessConfig::Security const&, dyld4::ProcessConfig::Logging const&, dyld4::SyscallDelegate&) + 469   frame #5: 0x0000000204a22481 dyld`dyld4::ProcessConfig::ProcessConfig(dyld4::KernelArgs const*, dyld4::SyscallDelegate&) + 105   frame #6: 0x0000000204a20486 dyld`start + 310

Hi All, I want to learn and write unit test cases using Mock class and stubs for MVVM design implementation. Also I want to test API calls using XCTestCase framweork. I need recommended guidelines or way for writing test cases for following class designs. I am facing problem for how to test code/data from mock class with actual class code.
