具有本地化UI的Xcode 7 UITests [英] Xcode 7 UITests with localized UI

问题描述

在我的应用程序中，我正在使用NSLocalizedString本地化我的应用程序.现在，我想切换到UITests并像这样使用habe Testcode:

In my App I'm using NSLocalizedString to localize my app. Now I want to switch to UITests and habe Testcode like this:

[tabBarsQuery.buttons["particiants"] tap];

这适用于英语，但不适用于其他语言.

This works for English but fails for other languages.

[tabBarsQuery.buttons[NSLocalizedString("PARTICIPANTS",comment:nil)] tap];

失败-可能是因为Localizable.strings在另一个捆绑包中.如何测试本地化的应用程序?

Fails - probably because Localizable.strings is in another bundle. How can I test a localized app?

推荐答案

我想实际测试UI功能的内容，而不仅仅是它们的存在，因此设置默认语言或使用可访问性标识符都不适合.

I wanted to actually test the content of UI features and not just their existence, so setting a default language or using the accessibility identifiers wouldn't suit.

这基于 Volodymyr 和

This builds on Volodymyr's and matsoftware's answers. However their answers rely on deviceLanguage which needs to be explicitly set in SnapshotHelper. This solution dynamically gets the actual supported language the device is using.

1. 将Localizable.strings文件添加到UITest目标.

2. 将以下代码添加到您的UITest目标:

1. Add the Localizable.strings files to your UITest target.

2. Add the following code to your UITest target:

var currentLanguage: (langCode: String, localeCode: String)? {
    let currentLocale = Locale(identifier: Locale.preferredLanguages.first!)
    guard let langCode = currentLocale.languageCode else {
        return nil
    }
    var localeCode = langCode
    if let scriptCode = currentLocale.scriptCode {
        localeCode = "\(langCode)-\(scriptCode)"
    } else if let regionCode = currentLocale.regionCode {
        localeCode = "\(langCode)-\(regionCode)"
    }
    return (langCode, localeCode)
}

func localizedString(_ key: String) -> String {
    let testBundle = Bundle(for: /* a class in your test bundle */.self)
    if let currentLanguage = currentLanguage,
        let testBundlePath = testBundle.path(forResource: currentLanguage.localeCode, ofType: "lproj") ?? testBundle.path(forResource: currentLanguage.langCode, ofType: "lproj"),
        let localizedBundle = Bundle(path: testBundlePath)
    {
        return NSLocalizedString(key, bundle: localizedBundle, comment: "")
    }
    return "?"
}

通过localizedString(key)

对于具有脚本代码的语言，localeCode将为langCode-scriptCode(例如，zh-Hans).否则，localeCode将为langCode-regionCode(例如，pt-BR). testBundle首先尝试通过localeCode解析lproj，然后回退到langCode.

For those languages with a script code, the localeCode will be langCode-scriptCode (for example, zh-Hans). Otherwise the localeCode will be langCode-regionCode (for example, pt-BR). The testBundle first tries to resolve the lproj by localeCode, then falls back to just langCode.

如果仍然无法获取捆绑包，则返回?"字符串，因此它将在寻找特定字符串的所有UI测试中失败.

If it still can't get the bundle, it returns "?" for the string, so it will fail any UI tests that look for specific strings.
