How to generate coverage test reports (Xcode 4.5 edition)

1. cd to your Xcode project and type

   git clone git@github.com:j4n0/XcodeCoverage.git
   cd XcodeCoverage
   wget http://downloads.sourceforge.net/ltp/lcov-1.10.tar.gz
   tar -zxvf lcov-1.10.tar.gz
   

2. Set the following build properties on both your main target and your SentestKit target, but only for the Debug configuration (expand the node, there are Debug and Release entries):

   Generate Profiling code       Yes
   Generate Test Coverage Files  Yes
   Instrument Program Flow       Yes
   

3. Install Xcode command line tools: Xcode > Preferences > Downloads > Command Line Tools.

4. In your main target, add a “Run Script” build phase to execute ./XcodeCoverage/exportenv.sh

5. Build your application, and run the tests.

6. Generate the coverage report from the XcodeCoverage typing: ./getcov
   Upon completion, the script will launch a browser with the html output.

If reports are not generated try this:

• Edit the plist of your application and add the following:

  UIApplicationExitsOnSuspend
  
  

  Then run your application and press Home. This will quit cleanly and generate the gcda files.
• If it still doesn't work, try using the iPad simulator instead.
