如何访问在XCUIApplication中设置的launchEnvironment和launchArguments，在XCode中运行UI测试？ [英] How to access launchEnvironment and launchArguments set in XCUIApplication, running UI tests in XCode?

问题描述

我已经尝试在我的UI测试 setUp（） XCUIApplication 实例中的属性>

I've tried setting attributes in the XCUIApplication instance, in my UI Tests setUp()

let app = XCUIApplication()
app.launchEnvironment = ["testenv" : "testenvValue"]
app.launchArguments = ["anArgument"]
app.launch()

in didFinishLaunch 当我运行我的UITests时，我试图在屏幕上显示这些

in didFinishLaunch I've tried to show these on screen when I run my UITests

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    if launchOptions != nil {
        for (key, value) in launchOptions! {  
            let alertView = UIAlertView(title: key.description, message: value.description, delegate: nil, cancelButtonTitle: "ok")
            alertView.show()
        }
    }

但我似乎无法找到我设置的参数和环境。有人知道怎么抓住它们吗？

But I can't seem to be able to find the arguments and environment I set. Anyone know how to get a hold of them?

推荐答案

如果设置 launchArguments 在UI测试中（Swift）：

If you set launchArguments in a UI Test (Swift):

let app = XCUIApplication()
app.launchArguments.append("SNAPSHOT")
app.launch()

然后使用以下内容在您的应用中阅读它们：

Then read them in your App using:

swift 2.x ：

if NSProcessInfo.processInfo().arguments.contains("SNAPSHOT") {
   // Do snapshot setup
}

Swift 3.0

if ProcessInfo.processInfo.arguments.contains("SNAPSHOT") {
}

要设置环境变量，请使用<$ c分别是$ c> launchEnvironment 和 NSProcessInfo.processInfo（）。environment 。

To set environment variables, use launchEnvironment and NSProcessInfo.processInfo().environment, respectively, instead.
