如何在 iOS 12 的 XCUITest 中关闭系统授权警报

Question

我仍然无法在 XCUITest 中对“照片库的授权请求”等系统警报做出反应。我尝试了以下代码 sn-ps。但它们都不起作用。有什么想法吗？

UI 中断监视器

addUIInterruptionMonitor(withDescription: "System alert") { (alerts) -> Bool in
    if alert.buttons["OK"].exists {
        alert.buttons["OK"].tap()
    }
    return true
}

XCUIApplication().sheets.buttons["Aufnahme"].firstMatch.tap()

等待 NSPredicate

XCUIApplication().sheets.buttons["Aufnahme"].firstMatch.tap()

let existsPredicate = NSPredicate(format: "exists == true")
let expectation = XCTNSPredicateExpectation(predicate: existsPredicate, object: app.alerts.firstMatch)
let result = XCTWaiter.wait(for: [expectation], timeout: timeout)
if result == .completed {
    app.alerts.firstMatch.tap()
} else {
    print("### TIMEOUT ###")
}

等待存在

XCUIApplication().sheets.buttons["Aufnahme"].firstMatch.tap()
app.alerts.firstMatch.waitForExistence(timeout: 10)

跳板解决方案

此解决方案基于Lepidopteron 的帖子。它通常可以工作，但似乎很慢（请参阅下面的日志）。在 t=14.51s 我点击按钮“打开照片库。然后系统警报直接出现在我的应用程序中。但随后一切似乎冻结了大约 70 秒。 在 t = 78.08 时，setPermission() 函数被调用。

有人遇到过类似的行为吗？

### OPEN PHOTO LIBRARY
    t =    14.51s Tap "Aufnahmen" Button
    t =    14.51s     Wait for bone.self.TargetShooter to idle
    t =    14.56s     Find the "Aufnahmen" Button
    t =    14.62s         Check for interrupting elements affecting "Aufnahmen" Button
    t =    14.84s     Synthesize event
    t =    14.98s     Wait for bone.self.TargetShooter to idle
    t =    75.08s         App animations complete notification not received, will attempt to continue.
### START AUTHORITATION PROCESS
    t =    75.08s Get number of matches for: Descendants matching type Alert
    t =    75.12s     Snapshot accessibility hierarchy for app with pid 13439
    t =    75.16s     Find: Descendants matching type Alert
### ALLOW SYSTEM ALERT
    t =    75.16s Find the Alert
    t =    75.16s     Snapshot accessibility hierarchy for app with pid 13439
    t =    75.23s     Find: Descendants matching type Alert
    t =    75.23s     Find: Element at index 0

    t =    75.33s     Find: Element at index 0
    t =    75.33s     Find: Descendants matching type Button
    t =    75.33s Checking existence of `Button`
    t =    75.33s     Snapshot accessibility hierarchy for app with pid 13439
    t =    75.39s     Find: Descendants matching type Alert
    t =    75.39s     Find: Element at index 0
    t =    75.39s     Find: Descendants matching type Button
    t =    75.39s     Find: Element at index 1
    t =    75.39s Find the Button
    t =    75.39s     Snapshot accessibility hierarchy for app with pid 13439
    t =    75.45s     Find: Descendants matching type Alert
    t =    75.45s     Find: Element at index 0
    t =    75.45s     Find: Descendants matching type Button
    t =    75.45s     Find: Element at index 1
    t =    75.59s Tap "OK" Button
    t =    75.59s     Wait for com.apple.springboard to idle
    t =    75.65s     Find the "OK" Button
    t =    75.65s         Snapshot accessibility hierarchy for app with pid 13439
    t =    75.72s         Find: Descendants matching type Alert

    t =    75.72s         Find: Element at index 1
    t =    75.83s         Check for interrupting elements affecting "OK" Button
    t =    75.88s             Snapshot accessibility hierarchy for app with pid 13439
    t =    75.93s             Find: Descendants matching type Alert
    t =    75.98s     Synthesize event
    t =    76.13s     Wait for com.apple.springboard to idle
### END AUTHORITATION PROCESS

Answer 1

这就是它在我的代码中的工作方式，试试吧：

var photoAccessGranted = XCTestExpectation(description: "photo access")


addUIInterruptionMonitor(withDescription: "system permissions") { (alert) -> Bool in
        print("1) addUIInterruptionMonitor:\(alert)")

        if alert.staticTexts["Put here the text that you get in the alert"].exists { // Photo permission
            alert.buttons["OK"].tap()
            self.photoAccessGranted.fulfill()
        }
