Hello world, I'm doing unit testing with Swift. I need to create a test for the registration process of an application. When I register, a confirmation link is sent to the specified email. How can I create a test that allows me to access the email and click on the link to confirm the registration?

Hi, I'm in the team maintaining company-wise CI for iOS build and test, which runs over 100 macs on the system with every stable versions of Xcode/simulators and the latest beta/rc. I've been terribly suffered from xcodebuild test failure with simulator destination on Xcode beta series since Xcode 14.x has changed its CoreSimulator behavior from static simruntime into simdisk-based dynamic runtime. (If you search for xcrun simctl runtime match set 'watchos9.1' 20S75 you can check what I have been fighting for.) At the end of numerous nightly overtimes I finally found out that ~/Library/Developer/CoreSimulator/RuntimeMap.plist is closely related to xcrun simctl runtime match command. If CoreSimulatorService relaunches when RuntimeMap.plist is corrupted (or missing), Chosen Runtime will be set as default SDK (pretty sure it is SDK version of iphoneos, not iphonesimulator) ex) $ sudo xcode-select -s /Applications/Xcode_15.2.app $ sed -i '' -e 's|21C62|21Cblabla|' ~/Library/Developer/CoreSimulator/RuntimeMap.plist $ sudo pkill -9 com.apple.CoreSimulator.CoreSimulatorService $ xcrun simctl runtime match list == Evaluation Results == appletvos17.2: SDK Version: 17.2 SDK Build: 21K354 Platform: com.apple.platform.appletvos Chosen Runtime: tvOS 17.2 (17.2 - 21K364) - com.apple.CoreSimulator.SimRuntime.tvOS-17-2 User Override: (null) Preferred: tvOS 17.2 (17.2 - 21K364) - com.apple.CoreSimulator.SimRuntime.tvOS-17-2 Default: 21K354 iphoneos17.2: SDK Version: 17.2 SDK Build: 21C52 Platform: com.apple.platform.iphoneos Chosen Runtime: 21C52 User Override: (null) Preferred: 21Cblabla Default: 21C52 watchos10.2: SDK Version: 10.2 SDK Build: 21S355 Platform: com.apple.platform.watchos Chosen Runtime: watchOS 10.2 (10.2 - 21S364) - com.apple.CoreSimulator.SimRuntime.watchOS-10-2 User Override: (null) Preferred: watchOS 10.2 (10.2 - 21S364) - com.apple.CoreSimulator.SimRuntime.watchOS-10-2 Default: 21S355 xros1.0: SDK Version: 1.0 SDK Build: 21N301 Platform: com.apple.platform.xros Chosen Runtime: visionOS 1.0 (1.0 - 21N305) - com.apple.CoreSimulator.SimRuntime.xrOS-1-0 User Override: (null) Preferred: visionOS 1.0 (1.0 - 21N305) - com.apple.CoreSimulator.SimRuntime.xrOS-1-0 Default: 21N301 The question is: Where exactly is the path or file that reflects this change? What file is Chosen Runtime of runtime match list tracking? When is the time to re-download and fix if it is corroded or not found? P.S. Thanks valexeev4 for letting me know where RuntimeMap plist is. https://developer.apple.com/forums/thread/738077?answerId=765617022#765617022

Hello! Since Xcode 15 came out, I've been having this issue with UI tests where the test runner hangs for 60s when the keyboard is presented. In the test logs I get this kind of messages: 00:07.588 Wait for com.example.app to idle 01:07.642 App event loop idle notification not received, will attempt to continue. Interestingly, this only appears to be happening in CI environments (I've tried Xcode cloud and Circle CI). It works fine on my local machine. Everything is fine with Xcode 14, but I can't keep my CI environment stuck on Xcode 14 forever. I've tried disabling animations using UIView.setAnimationsEnabled(false), but it did not fix the problem. Here are the full logs of what it takes to fill out a text field: logs.txt

I'm trying to write a unit test for a SwiftData migration. In the teardown function I delete the SQLite container files, but then the underlying sqlite library complains. There must be a way to gracefully terminate the SwiftData container before I delete the files, but I don't see how. Simplying nil-ifying the references doesn't work. I don't see any obvious close functions, so I hope someone knows a non-obvious function. override func tearDownWithError() throws { // Cleanup resources // -- DOES NOT CLOSE UNDERLYING SQLITE ACCESS -- self.container = nil self.context = nil // Delete database do { try FileManager.default.removeItem(at: self.url) } catch { // Ignore file not found, report everything else. let nserror = error as NSError if nserror.domain != "NSCocoaErrorDomain" && nserror.code == 4 { throw error } } try? FileManager.default.removeItem(at: self.url.deletingPathExtension().appendingPathExtension("store-shm")) try? FileManager.default.removeItem(at: self.url.deletingPathExtension().appendingPathExtension("store-wal")) } I get these errors for .store, store-shm, and .store-wal: BUG IN CLIENT OF libsqlite3.dylib: database integrity compromised by API violation: vnode unlinked while in use: /Users/(ME)/Library/Developer/XCTestDevices/C52F4E12-EB4F-4639-9866-C3A7126155FA/data/Containers/Data/Application/B0EE90C6-B95D-4185-890D-6F20766B9B3B/tmp/test1.store invalidated open fd: 11 (0x11) If the worst comes to the worst, I'll work around it by using a differently-named container for each test, but as they're in tmp they'll get cleaned up for me eventually.

I am running xctests from command line on XCode 15.2 on iOS 17.2 simulators. As per WWDC2021 video on Memory issues, I am passing `-enablePerformanceTestsDiagnostics Yes' in following xcodebuild command. xcodebuild test -project project_name.xcodeproj -scheme test-scheme -destination 'platform=iOS Simulator,name=iPhone 15 Pro' -enablePerformanceTestsDiagnostics YES Final logs before test results: Tests-Runner(16873) MallocStackLogging: stack logs deleted from /private/tmp/stack-logs.16873.10148c000.Tests-Runner.M6gFw .xcresults is generated but no memgraph file is attached along with it.

Hi there, I'm trying to figure out an issue I'm seeing where the xcresult bundle isn't including the crash report after building and running with xcodebuild. I have a simple test app that has a single button that intentionally crashes and an XCUI test to run it. The UI Test also passes which can probably be explained by the lack of any asserts after clicking the button, but I assumed the app crashing would fail the test. The app itself is a Mac OS app with a single button called "Crash" that links to a method: - (IBAction)crash:(id)sender { @throw NSInternalInconsistencyException; } and a test method: XCUIApplication *app = [[XCUIApplication alloc] init]; [app launch]; XCUIElement *crashButton = [[XCUIApplication alloc] init].windows[@"Window"].buttons[@"Crash"]; XCTAssert([crashButton exists]); [crashButton click]; There is an ips file corresponding to the crash in ~/Library/Logs/DiagnosticReports so the crash gets written, but the test passes. After using xcresulttool to dump the Diagnostics folder from the xcresult bundle, I see these lines in the session log: 10:59:20.790 xcodebuild[23184:6634391] Handling Crash: MacAppTest (23189) main. libsystem_c.dylib: abort() called 10:59:20.792 MacAppTestUITests-Runner[23188:6635181] Process crashed with pid:23189 path:/Users/USER/Library/Developer/Xcode/DerivedData/MacAppTest-dxrjhasbuvyffhenipmdemzdpdht/Build/Products/Debug/MacAppTest.app/Contents/MacOS/MacAppTest bundleID:com.company.MacAppTest summary:main 10:59:20.792 MacAppTestUITests-Runner[23188:6635181] Ignoring crash for com.company.MacAppTest:23189 because we are not currently tracking it 10:59:21.371 MacAppTestUITests-Runner[23188:6634605] Returning result XCTWaiterResultCompleted for waiter <XCTWaiter: 0x6000025fd4d0> 10:59:21.371 MacAppTestUITests-Runner[23188:6634605] Wait <XCTWaiterWait: 0x600003e1b540> completed after 1.003s 10:59:21.371 MacAppTestUITests-Runner[23188:6634605] cleaning up delay The Ignoring crash for com.company.MacAppTest:23189 because we are not currently tracking it is what I suspect is the issue.

Hello, I'm having an issue with Unit testing on xCode 15.2 and macOS Sonoma. I'm trying to run unit testing and it hangs for a long time and then fails, previously I was able to run my unit testing on simulator with iOS 14, however after upgrading the xCode and the macOS I'm unable to use simulators with iOS 14 and my unit testing keeps failing. I have another device which is running macOS Ventura and I can run my unit testing on it without any problems using simulators with iOS 14 on xCode 15.0. Please note the issue is not with the xCode version because I tried downgrading and still have the same issue. I tried every solution i can find on this forum and others, I couldn't find anything that would help. I can't attach the dump log file directly since it's big so please use the link below https://drive.google.com/file/d/1v_gpCLhEuUdqFF6aCfrGislYWV8ZE8Qm/view?usp=share_link

Hi. I am measuring performances of methods in unit test on Xcode. Measuring performances on release build is important since you can know if a performance issue will be solved by compiler or not. However, when you specify its build as release, you cannot use @testable. Please tell me any manners. Thanks.

Xcode is not not picking up when I make changes to my unit test files when running tests. The only way is to clean the whole project and rebuild again. Any ideas why? I recently tried Xcode cloud and this behaviour started after removing that option

Since I start to wrote UITest, this keep happened with no waring, following image is the log, sensitive info has been replaced. However, once I run app, then run test again, UITest just work out, it seems like a wired but, and the method just a working around bug to me,

I am writing a SPM based project for MacOS. In this project? I need to access MacOS Keychain. I am write a swift test built by SPM testTarget(). I can see it generates a bundle ./.build/x86_64-apple-macosx/debug/MyProjectTests.xctest with an executable: % file ./.build/x86_64-apple-macosx/debug/MyProjectPackageTests.xctest/Contents/MacOS/MyProjectPackageTests ./.build/x86_64-apple-macosx/debug/MyProjectPackageTests.xctest/Contents/MacOS/MyProjectPackageTests: Mach-O 64-bit bundle x86_64 This bundle file cannot be executed. How can I execute its tests? I tried with xcodebuild test-without-building -xctestrun ./.build/x86_64-apple-macosx/debug/MyProjectPackageTests.xctest -destination 'platform=macOS' without any chance. Obviously the next question is can I 'simply' add entitlement to this bundle with codesign to fix my enttilement error. My error when running the test is A required entitlement isn't present.

In my iOS project, there is an infrequent crash related to virtual memory problem. Therefore, I plan to use UITest in combination with Product/Perform Action/Profile "TestCaseName" to conduct Game Performance-type testing. This allows the automatic testing to continuously operate until the profile stops recording upon a crash. This enables me to observe the various states of the program at the time of the crash. However, I have found that the UITest using Profile is highly unstable. The UITestCase often terminates unexpectedly during execution, leading to failed tests (Instruments is still working). Sometimes, the app is terminated immediately after startup. It seems that the use of sleep() in the code can easily cause interruption issues, which do not occur during normal UI testing. I am wondering if anyone has experience using Profile for UITest and whether they have encountered the issues I described." Working Environment: XCode14.3.1, iPhone Device iOS17.2

I have a CI pipeline, which runs unit tests and exports the code coverage. I need to run the sonar-scanner tool to export the report to the sonarqube server running on a server that can only be accessed over a VPN only. How can I do this?

I am directed from https://discuss.appium.io/t/create-multiple-instances-of-the-same-app/41266/14?u=lxnm, the context is that Appium max2 driver is implementing the activating of MacOS app using XCTest API methods. There are 2 ways to implement the activating of the app, using app path (calling initWithURL) and bundle id (calling initWithBundleIdentifier). This pull request shows how the XCTest methods are called when using the Mac2 driver, specifically in the file WebDriverAgentMac/WebDriverAgentLib/Routing/FBSession.m. The problem is that I am able to launch my MacOS app(it is a company app) using bundle id, but when I launch the app with app path, I receive XcodeBuild errors: [WebDriverAgentMac] [xcodebuild] XCTExpectFailure: matcher accepted Assertion Failure: Failed to launch com.company.companyApp: You do not have permission to run the application “companyApp”. You don’t have permission. To view or change permissions, select the item in the Finder and choose File > Get Info. (Underlying Error: The operation couldn’t be completed. Operation not permitted) I followed this to enable R+W permissions to all users, but the same error is displayed.

I am currently working on a SwiftUI project and I am trying to write a UI test for a DatePicker. However, I am having trouble interacting with the DatePicker in the test. Here is the code for the DatePicker in my SwiftUI view: DatePicker("Date", selection: $date, displayedComponents: [.date]) .datePickerStyle(.graphical) .labelsHidden() .frame(width: 150) And here is the code for my UI test: func testSelectingDateChangesMainView() throws { let app = XCUIApplication() app.launch() let dateDatePicker: XCUIElement = app.windows["mainUI-AppWindow-1"].datePickers["Date"] dateDatePicker.click() let col = dateDatePicker.descendants(matching: .any) print("\(dateDatePicker.debugDescription), \(col.debugDescription)") } When I run the test, it seems like the DatePicker does not have any descendants, so I am unable to select a date. Does anyone have any suggestions on how I can interact with a .graphical style DatePicker in a UI test? Any help would be greatly appreciated. Thank you, OnlyForF1

Hi! I'm experimenting with Xcode performance testing. I'm specifically focusing on XCTMemoryMetric. I have a demo project with two performance tests that do some work wrapped with XCTestCase.measure. I can navigate to my Report navigator in Xcode and see the memory footprints of these two tests… but I only see how to view them individually: From this screen it looks like I have the ability to Export this benchmark to CSV. My question is what my options are for viewing all my XCTestCase.measure tests together. I see the Duration for both tests… but I don't see any way to view the memory benchmarks for all my tests in just one place: Ideally… I would also like to run these tests and produce one CSV file (or XML or JSON) report. I'm not opposed to using command line for this (if the option exists there) but Xcode also works for me. I'm also flexible whether or not these tests live in a Swift Package or directly in an Xcode project if that makes any difference. Any more advice about how to set up these performance tests? Thanks!

We recently updated to Xcode 15.1 and start using iOS 17.2 simulator and ran into a blocker issue with out UITests. Setting accessibility identifier on a UIButton with image no longer works. It seems iOS automatically set the label to the file name used for the button and ignore (overwrite) the id and value we set in code. iOS 17.0 with Xcode 15.1 still works. I spent 2 days on this and still cannot find a solution. Anyone had similar issue? I did file a feedback https://feedbackassistant.apple.com/feedback/13515676 Thanks!
