在UI测试中无法访问字符串本地化（Xcode 7） [英] Can't get access to string localizations in UI Test (Xcode 7)

问题描述

所以我有一种情况，我有一些经验证的textFields。我正在尝试运行UI测试，当他们失败时，他们会收到警告，弹出错误消息（可能是不同的消息，具体取决于哪些字段无效以及以何种方式）。

So I have a situation in which I have a few textFields that are validated. I'm trying to run a UI test, and when they fail they will get an alert to pop up with an error message (potentially a different message depending on what fields are invalid and in what way).

我想测试一下，不仅会出现警报，还会显示正确的消息。我遇到的问题是我需要获取本地化的文本进行比较（如果我用英语以外的其他语言运行测试），但是当我在UITest中调用NSLocalizedString时，它无法收集正确的本地化字符串（只是返回键[默认]）

I'd like to test that not only that an alert appeared, but that the correct message is displayed. The problem I'm having is that I need to get the localized text for comparison (if I run tests in another language other than english), but when I call NSLocalizedString in the UITest it can't gather the correct localized string (just returns the key [default])

我尝试将 localizeable.strings 文件添加到UITest目标，但是无济于事。有没有人知道这是否可行？

I've tried adding the localizeable.strings files to the UITest target, but to no avail. Does anyone know if this is possible?

编辑旁注：我还尝试在 UIAlertView 但是当我查询该可访问性标识符时它不存在，我只能使用看起来倒退的警报标题来查询它。

edit as a side note: I also tried setting an accessibility identifier on the UIAlertView but when I query with that accessibility identifier it doesn't exist, I can only query it using the title of the alert which seems backwards.

推荐答案

在UI测试中，主包似乎是一个随机启动器应用程序。这就是.strings文件没有出现的原因：即使你将它添加到测试包中，NSLocalizedString也会检查错误的包。要解决这个问题，你需要这样的调用：

In the UI tests, the main bundle seems to be a random launcher app. That's why the .strings file doesn't appear: even though you added it to your test bundle, NSLocalizedString is checking the wrong bundle. To get around this, you need an invocation like this:

NSLocalizedString("LOCALIZATION_KEY", bundle: NSBundle(forClass: AClassInYourUITests.self), comment: "")

您可能希望将其纳入辅助方法。

Which you might want to pull into a helper method.
