当由Xcode bot运行时，文本在文本视图中键入时，UI测试失败 [英] UI test fails when it types text into a text view when run by an Xcode bot

问题描述

我有以下XCTest UI测试，它将文本键入文本视图。

I have the following XCTest UI test that types text into a text view.

let textView = app.textViews.elementBoundByIndex(0)
textView.tap()
textView.typeText("Hello world")

当作为Xcode机器人运行时，它会为 typeText 调用显示以下错误。

When run as an Xcode bot it shows the following error for the typeText call.

断言：UI测试失败 - 失败：等待关键事件完成超时

Assertion: UI Testing Failure - failed: Timed out waiting for key event to complete

有趣的是，当我从同一台计算机上的Xcode手动运行时，测试通过了。在升级到Xcode 7.1 / iOS 9.1之前，此测试也通过了Xcode bot。可能是问题的根源是什么？

Interestingly, when I run it manually from the Xcode on the same computer the test passes. This test also passed in Xcode bot before upgrade to Xcode 7.1 / iOS 9.1. What can be the source of the problem?

这是一个带有UI测试的独立演示：

Here is an isolated demo with the UI test: https://github.com/exchangegroup/UITestTextViewDemo

iOS 9.1模拟器，OS X 10.11.1 （15B42），Xcode 7.1（7B91b），OS X Server 5.0.15（15S4033）

iOS 9.1 Simulator, OS X 10.11.1 (15B42), Xcode 7.1 (7B91b), OS X Server 5.0.15 (15S4033)

报告给Apple。

推荐答案

我为我的案子找到了一个解决方案，我希望它对你有帮助。

I found a solution for my case and I hope it helps you as well.

在我的 setUp（）和 tearDown（）（我知道这似乎多余）我把 XCUIApplication（）。terminate（） 。这是确保应用程序在运行下一个测试之前终止，并且它似乎正在完成工作。

In my setUp() and tearDown() (seems redundant I know) I put XCUIApplication().terminate(). This is ensuring that the app is terminated before running the next test and it seems to be doing the job.

override func setUp() {
    XCUIApplication().terminate()
    super.setUp()
    continueAfterFailure = false
    XCUIApplication().launch()
}
override func tearDown() {
    super.tearDown()
    XCUIApplication().terminate()
}

我向Apple提交了一个错误，但目前这让我了解了你所看到的错误。希望有所帮助！

I filed a bug with Apple but for the time being this is getting me around the error that you were seeing. Hope that helps!
