Delay/Wait in a test case of Xcode UI testing

I am trying to write a test case using the new UI Testing available in Xcode 7 beta 2. The App has a login screen where it makes a call to the server to login. There is a delay associated with this as it is an asynchronous operation.

Is there a way to cause a delay or wait mechanism in the XCTestCase before proceeding to further steps?

There is no proper documentation available and I went through the Header files of the classes. Was not able to find anything related to this.

Any ideas/suggestions?

Solution

  • Asynchronous UI Testing was introduced in Xcode 7 Beta 4. To wait for a label with the text "Hello, world!" to appear you can do the following:

    let app = XCUIApplication()
app.launch()

let label = app.staticTexts["Hello, world!"]
let exists = NSPredicate(format: "exists == 1")

expectationForPredicate(exists, evaluatedWithObject: label, handler: nil)
waitForExpectationsWithTimeout(5, handler: nil)
