Automating the Gaps of Unit Testing Mobile Apps

2 744 vues

Publié le

Apple has provided an orchestra of instruments for developers to use to fine tune their apps and create the best user experience possible. At compile time, within the simulator, on the device and in the field. Apple offers some solid advice to offer developers on how to make their apps the best they could possibly be. This session will look at the series of tools available from using static analyzers, to knowing when to use the simulator, and when using the device is required to collect the data necessary to understand just how an application is performing. It will also show how to gather information from testers that are testing the app live in out in real world scenarios rather then just in the team room.

Leaks The Leaks profiling template uses the Allocations and Leaks instruments to measure general memory usage in your app and check for leaks— memory that has been allocated to objects that are no longer referenced and reachable. https://developer.apple.com/library/ios/documentation/DeveloperTools/Conceptual/InstrumentsUserGuide/FindingLeakedMemory.html iOS Developer Library - Instruments User Guide

  23. 23. Allocations The Allocations profiling template uses the Allocations and VM Tracker instruments to measure general and virtual memory usage in your app. However, to track down abandoned memory that’s been allocated but isn’t needed again, you’ll focus strictly on the Allocations instrument. This instrument measures heap memory usage and tracks allocations, including specific object allocations by class. https://developer.apple.com/library/ios/documentation/DeveloperTools/Conceptual/InstrumentsUserGuide/FindingAbandonedMemory.html iOS Developer Library - Instruments User Guide
