解除警报XCUITest

Question

我试图在我的XCUITest套件中取消警报，我目前正在使用

app.alerts.buttons["OK"].tap()

使用此方法可以解除警报，但是应用程序继续尝试点击按钮，然后失败，错误消息是"UI测试失败-没有找到警报的匹配“。

这是控制台输出

有没有更好的办法来解决这个问题？还是有办法解决我哪里出了问题？在这件事上困惑了一段时间！

Answer 1

我改进了@ answer 3271402的答案

addUIInterruptionMonitorWithDescription("alert description") { (alert) -> Bool in
    let alertButton = alert.buttons["OK"]
    if alertButton.exists {
        alertButton.tap()
        return true
    }
    return false
}
app.tap()

如果警报存在，只需点击。如果警报没有发生，则返回false，并在点击应用程序和结束后返回。

Answer 2

一种方法在XCTest中用于警报处理：

addUIInterruptionMonitorWithDescription("iTunesStoreAlert") { alert in
    alert.buttons["OK"].tap()
    return true
}

你可以把这个放在你的测试开始。或者你在哪里会收到警报

Answer 3

请注意，addUIInteruptionMonitorWithDescription方法只能用于正常工作流程之外的警报。每Apple1

重要 当警报或其他模态UI是测试工作流的预期部分时，不要编写UI中断监视器。测试不会使用监视器，因为模态UI没有阻塞测试。一个UI测试只会尝试它的UI中断监视器，如果它需要与之交互以完成测试的元素被来自不相关UI的中断所阻塞。

如果警报是由正常流提供的，则只需使用普通的XCTestCase方法：

 expectation(
     for: NSPredicate("exists == true"),
     evaluatedWith: XCUIApplication().staticTexts["Error Sending Mail"],
     handler: nil) { error in
     // handle failure here
 }

 XCUIApplication().buttons["OK"].tap()
