iNVASIVECODE - Blog • Flags: very useful when debugging with... There is a very nice feature in Instruments that helps you to point your loupe to a very precise spot in your code. I am writing an app that process images captured by the camera in real-time. I am using GCD to launch different queues both in asynchronous and synchrous mode and when it is time to debug, it’s a mess. Most of the time I need to know extactly what is doing what and where something is executing. Using the breakpoints interrupting the execution and analyze the status of your variable, it is not always useful in a multi-threaded environment, because you alter the real flow of your application.

Performance Session To use this feature, you need to add to your Xcode project the DTPerfomanceSession.framework and #import into the class you want to analyze. Now, wherever you need to send a signal to Instruments from your app, you just add this line of code: Geppy. iPhoneUnitTesting - google-toolbox-for-mac - How to do iPhone un. For a long time, Apple didn't provide a way to do iOS unit testing, so Google Toolbox For Mac helped fill that gap by providing all the support to write tests with SenTest just like you could for OS X. But as of Xcode 4.x, Apple has supported unit testing iOS and taken it even further than before with Xcode integration for controlling what tests are run, debugger support, etc. Google Toolbox For Mac on iOS now supports both the older Google Toolbox For Mac only way (building a App and GTM does everything) and working in parallel with Apple's support (like Google Toolbox For Mac does for OS X testing; using the Apple provided testing frameworks, just adding additional functionality).
This is now the suggested way to using Google Toolbox For Mac for unit testing on iOS. Basic Project Setup Start by follow Apple's UnitTesting documentation. That's it, you'll get the added support the GTM provides to test cases using the stock Apple supported SenTest.
