如何在iOS 12中的XCUITest中关闭系统授权警报

Question

我仍然无法在XCUITest中以系统警报（例如“照片库的授权请求”）作出反应。我尝试了以下代码片段。但是它们都不起作用。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)

Sprinboard解决方案

此解决方案基于Lepidopteron的帖子。它可以正常工作，但似乎很慢（请参阅下面的日志）。在t = 14.51s，我点击“打开照片库”按钮。然后系统警报直接出现在我的应用程序中。但是随后一切似乎停滞了约70秒。在t = 78.08时，调用setPermission()函数。

有人经历过类似的行为吗？

### 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 =    75.23s Get number of matches for: Descendants matching type Button
    t =    75.29s     Snapshot accessibility hierarchy for app with pid 13439
    t =    75.33s     Find: Descendants matching type Alert
    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 0
    t =    75.72s         Find: Descendants matching type Button
    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

这就是我的代码的工作方式，请尝试：

var photoAccessGranted = XCTestExpectation（描述：“照片访问”）

addUIInterruptionMonitor（withDescription：“系统权限”）{（警告）->笨蛋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()
        }
