How to detect if iOS app is running in UI Testing mode

Question

I would like my app to run special code (e.g. resetting its state) when running in UI Testing mode. I looked at environment variables that are set when the app is running fr

I didn't succeed with setting a launch environment, but got it to work with launch arguments.

In your tests setUp() function add:

let app = XCUIApplication()
app.launchArguments = ["testMode"]
app.launch()

In your production code add a check like:

let testMode =  NSProcessInfo.processInfo().arguments.contains("testMode")
if testMode {
  // Do stuff
}

Verified using Xcode 7.1.1.
