ios - UITest 中断处理程序调用 tap() 两次

Question

我的 UITest 需要点击一个按钮，UIInteruptionMonitor 应该处理它。然而，发生的是按钮被点击，中断出现并得到处理，然后它再次尝试点击按钮。它似乎认为它实际上并没有点击按钮，当它有......

我有以下代码:

addUIInterruptionMonitor(withDescription: "Permissions") { alert -> Bool in
    let okButton = alert.buttons["OK"]
    if okButton.exists {
      okButton.tap()
    }

    return true
}

app.buttons["Enable"].tap()

接下来会发生什么:

t =    91.24s     Find the "Enable" Button
    t =    91.40s     Check for interrupting elements affecting "Enable" Button
    t =    91.42s         Wait for com.apple.springboard to idle
    t =    91.85s     Found 1 interrupting element:
    t =    91.86s         Find the "“MyApp” Would Like to Access the Camera" Alert
    t =    92.03s         "“MyApp” Would Like to Access the Camera" Alert from Application 'com.apple.springboard'
    t =    92.03s     Invoking UI interruption monitors for "“MyApp” Would Like to Access the Camera" Alert from Application 'com.apple.springboard'
    t =    92.03s         Invoking Permissions
    t =    92.04s             Checking existence of `"OK" Button`
    t =    92.21s             Tap "OK" Button
    t =    92.21s                 Wait for com.apple.springboard to idle
    t =    92.50s                 Find the "OK" Button
    t =    92.66s                 Check for interrupting elements affecting "OK" Button
    t =    92.82s                 Synthesize event
    t =    93.14s                 Wait for com.apple.springboard to idle
    t =    93.54s         Verifying handling...
    t =    93.54s             Check for interrupting elements affecting "Enable" Button
    t =    93.55s                 Wait for com.apple.springboard to idle
    t =    94.10s         Confirmed successful handling of interrupting element
    t =    94.10s     Synthesize event
    t =    95.39s         Scroll element to visible
    t =    96.55s         Failed: Failed to scroll to visible (by AX action) Button, label: 'Enable', error: Error kAXErrorCannotComplete performing AXAction 2003 on element AX element pid: 62934, elementOrHash.elementID: 140664883255456.613
    t =    97.57s     Retrying `Tap "Enable" Button` (attempt #2)

这是正常的。当被系统警报中断时，无法执行预期的操作，因此在成功处理中断后重试。

更一般地说，您必须在处理程序中检查您是否成功处理了中断(例如，您找到了 ok 按钮并可以点击它)，否则，您必须返回 false。
