Conclusion
“Let’s face it debugging code is twice as hard
as writing the code in the first place.
Therefore, if you write code as cleverly as
possible, you are, by definition, not smart
enough to debug it.” -- Kerningham
“Testers don’t break things; they like to
dispel the illusion that things work.” -- Kaner,
Bach, Pettichord

iOS XCUITest framework
● XCUIApplication
A proxy for an application that can be launched and terminated
● XCUIElementQuery
For locating UI Elements
● XCUIElement
Gestural interactions such as : tapping, pressing, swiping,
rotating, typing, etc.
● XCTAssert
© @devopsgirls 2019

36.
Implementation
(refer to : developer.apple.com/.../xctest/user_interface_tests)
● Query UIElement -> button, cell, image, text, menu, etc
Eg: XCUIApplication.staticTexts[“Sign In”]
● Interact UIElement -> click, tap, swipe, etc
Eg: XCUIApplication().buttons[“save”].tap()
● XCTest Assertion
Eg: XCTAssertTrue(XCUIApplication.staticTexts[“test”].exists)
