Testing in iOS

In this talk, I discussed how to test your iOS application in three different ways: unit testing, automated UI testing, and performance testing. Testing is pretty important. You should do it.

I show some basic uses of GHUnit and several things in Instruments.

19. Automated Testing
23. var target = UIATarget.localTarget(); var application = target.frontMostApp(); var window = application.mainWindow(); var view = window.elements()[0];
24. var buttons = window.buttons(); // Check for a button on screen if (buttons.length != 1) { UIALogger.logFail("FAIL: The button is missing."); } else { UIALogger.logPass("PASS: There is a button on the screen."); }
25. // Make sure it's the button we want var button = buttons.firstWithName("Tap Me"); if (!button || button.toString() == "[object UIAElementNil]") { UIALogger.logFail("FAIL: The button is missing."); } else { UIALogger.logPass("Pass: The button is there."); }
26. // Tap the button button.tap(); // Check for the alert var alert = application.alert(); if (!alert || alert.toString() == "[object UIAElementNil]") { UIALogger.logFail("FAIL: The alert was not shown after pressing the button."); } else { UIALogger.logPass("PASS: The alert was shown after pressing the button."); }
