a hole, I know that area is lacking unit tests.Sinkhole by Salim Virji, used under CC BY-SA 2.0(Be careful, the opposite isn't true: Just because some code has been touched by unit test execution doesn't mean it's actually covered. If altering the behavior of the code causes a test to fail, then you know it's covered.)Many people use CoverStory, a a code coverage browser app written by my friend Dave MacLachlan. Others use gcovr to integrate code coverage into their Jenkins continuous integration. Me, I use lcov because it lets me exclude third-party libraries from the measurements before generating an https://bugs.launchpad.net/bugs/1246387 HTML report.When a project is built from the command-line with xcodebuild, it places build artifacts into a "build" folder, kind of like the old days. But I want to measure coverage of unit tests as I run them from Xcode itself. This complicates things because build artifacts go into some obscure DerivedData subfolder. I solve this by having the build process export some of the http://qualitycoding.org/xcode-code-coverage/ project's environment variables to a file. I'll show you where to get the shell scripts I use to do all this.Download the code coverage toolsI have a GitHub repository called XcodeCoverage. You'll probably want to make some per-project changes. So if you use git for your projects, think about how you want to manage your fork - branch - submodule workflow.Place the XcodeCoverage folder in the same folder as your Xcode project.Update: The easiest way to incorporate XcodeCoverage is via CocoaPods, as long as you don't want to customize the exclusion rules.Then download lcov-1.10. Place the lcov-1.10 folder inside the XcodeCoverage folder.Also (if you haven't done so already) go to Xcode Preferences, into Downloads, and install Command Line Tools to get Xcode's coverage instrumentation.Set up your projectFirst, I assume you're using Xcode 4.5. If so, you're in luck: It's easy. (Code coverage used to be a little more complicated in earlier versions of Xcode, as Claus Broch describes in Code Coverage with Xcode 4.2 and Code Coverage and fopen$UNIX2003 Problems.)The first steps are the same, regardless of what coverage tool you use. Select your project, and go into its Build Settings. (I like to

Hi All, I used to run with gcov 4.3.3 and it went very well with lcov 1.7 and when I upgraded to lcov 1.8, one of .gcda file hangs as geninfo is calling now gcov with -a. So I decided to upgrade to gcov 4.4.4 hoping that this will solve the problem but unfortunately lcov doesn't wotk well with it. Attached you will find the test case gcov-4.4.4-test.tar.gz. When extracting you will find two directories "src" and "build" First open file build/linux/vsim/Makefile to put the gcov locations for 4.3.3 and 4.4.4 then do the following: 1- cd build/linux 2- make -C vsim all make: Entering directory `/u/rhino/aossman/test_gcov/build/linux/vsim' rm -rf x.o x.exe x.gcno a.out x.gcda my.info /u/apache/htdocs/qa/ahmed /u/prod/gnu/gcc/20100521/gcc-4.4.4-linux/bin/gcc -m32 -Wa,--32 -Wall -g -fprofile-arcs -ftest-coverage ../../../src/vsim/x.c -o x.exe x.exe 3 is divisable by 3 6 is divisable by 3 9 is divisable by 3 cd ../../..;/u/rhino/lcov-ws/utils/analysis/lcov/bin/lcov -d build/linux -c -o my.info --gcov-tool /u/prod/gnu/gcc/20100521/gcc-4.4.4-linux/bin/gcov Capturing coverage data from build/linux Found gcov version: 4.4.4 Scanning build/linux for .gcda files ...
