Design Patterns in XCUITest

Design Patterns in XCUITest

• Page Object

• Fluent Interface

• Wait until page/element load

• Using check() instead of grab & hope

• Use Launch Argument to Set Up

• Launch Arguments

Launch Arguments

MyAppUITest.swift
...
override func setUp() {
  super.setUp()

  let app = XCUIApplication()
  app.launchArguments.append("ui-testing")
  app.launch()
}
...

MyAppDelegate.swift
...
func setupModel() -> Model {
  let uiTesting = NSProcessInfo.processInfo().arguments.contains("ui-testing")

  let model = uiTesting ? StubModel() : NetworkModel()

  return model
}
...

NSUserDefaults

MyAppUITest.swift
...
override func setUp() {
  super.setUp()

  let app = XCUIApplication()
  app.launchArguments.appendContentsOf(["-ui-testing","YES"])
  app.launch()
}
...

MyAppDelegate.swift
...
func setupModel() -> Model {
  let defaults = NSUserDefaults.standardUserDefaults()
  let uiTesting = defaults.boolForKey("ui-testing")

  let model = uiTesting ? StubModel() : NetworkModel()

  return model
}
...
