How do I generate coverage reports for fork()'d children using gcov/lcov?

问题 I'm having trouble generating coverage reports for a project of mine -- it seems that the lines in the child process after a fork are never hit, althought they clearly are in reality. Here is the coveralls report of the forking part (The results are the same with lcov+genhtml), and the build logs. The project uses autotools with libtool to build, and packs everything as a static library. (configure.ac, library makefile.am, tests makefile.am) I tried to add the coverage flags to the tests, and

What are your tips for interpreting gcov output in order to improve coverage?

问题 I'm successfully using gcov in my project: I can build my project with gcov flags: -fprofile-arcs -ftest-coverage I link with the -lgcov option I run my unit test program and lots of gcda and gcno files are produced. I run gcov lots of times and lots of gcov files are produced. I summarise the results and produce a list of lines like this: #####: 42: virtual double run_time() const { return 0; } I then go 'doh!' and write a test which calls that missing method. The above example line is quite

gcov creates .gcov files in the current directory. Is there any way to change this?

I'm running gcov/gcc 4.1.2 on RHEL. When I want to specify a directory for the gcov files. Any ideas on how to do this? Run gcov from the directory where you want its files to be created. You'll have to use the -o argument to tell it where to look for the .gcno/.gcda files. See gcov's docs for more info. 来源： https://stackoverflow.com/questions/1759475/gcov-creates-gcov-files-in-the-current-directory-is-there-any-way-to-change-th

Eclipse gcov missing highlighting in code

由 不羁岁月 提交于 2019-12-05 22:15:21
I build my C++ project with "Generate gcov information", I run it under the "Gcov" profiler from the Linux Tools repository, and I get a nice coverage overview in the "gcov" view. But when I double click a file (one with about 92 % for example) the editor view that pops up has no coverage highlighting. I observe this on both x86_64/xenial/Mars and i386/hardy/Luna. What am I doing wrong? 来源： https://stackoverflow.com/questions/37851722/eclipse-gcov-missing-highlighting-in-code

Can I install gcov tool in windows? Or can I take plug-in of this tool in eclipse in windows? I am very new to this tool. I don't have any idea about this tool. Please help me to get the information of this tool. please tell me the requirements to run this tool on my machine. Where can I get more information about gcov and also please provide a link from where I can download this tool. Does gcov tool accepts only c/c++ files or it also takes header files(*.h) as input? Can I install gcov tool in windows? Yes. We use gcc to build QNX projects in Windows. Where can I get more information about

How does one get the actual function names from these output

由 为君一笑 提交于 2019-12-05 03:39:38
I use boost test for unit testing and gcov and lcov for measuring the coverage. Unfortuanlly genhtml generates reports like that for function coverage: I now want to know what the function _ZN7UtilLib11ProgressBarC2EjdRSo actually is. So far I can not correlate this function to any of the class interface of ProgressBar: class ProgressBar { public: explicit ProgressBar( unsigned int expected_count, double updateInterval = 30, std::ostream& os = std::cout); unsigned int operator+=(unsigned int increment); unsigned int operator++(); unsigned int operator++(int i); } Can any one help me how to

Is it possible code coverage of a shared library using gcov?

问题 I try to test an executable which uses OpenCV shared library. When using gcov to know what code lines were covered I only get info about my .cpp files and .hpp of the library. No info is shown about .cpp files of the library. I compiled and linked with -pg --coverage flags. 回答1: Yes, gcov can give coverage information about a shared library. If I remember correctly from the problems I had getting this to work on my project, you're probably not including the --coverage flag on the linking of

Why does gcov report in-class function definitions as not executable?

由 家住魔仙堡 提交于 2019-12-04 18:58:46
It seems like gcov does not report inline definitions of class methods as executable lines. Example: #include <iostream> struct Foo { void bar() {} void baz() {} }; int main() { Foo foo; foo.bar(); } If I compile the above program with g++ -g -O0 -ftest-coverage -fprofile-arcs -o main main.cpp , run it, and call gcov on it, I get the following report: -: 0:Source:main.cpp -: 0:Graph:main.gcno -: 0:Data:main.gcda -: 0:Runs:1 -: 0:Programs:1 -: 1:#include <iostream> -: 2: -: 3:struct Foo { 1: 4: void bar() {} -: 5: void baz() {} -: 6:}; -: 7: 1: 8:int main() { -: 9: Foo foo; 1: 10: foo.bar(); 4:

Is code coverage already working for Swift?

问题 I am trying to setup test code coverage for a Swift application on Xcode 6 Beta 4. I was able to do so in the past using ObjectiveC with Xcode 5, however I think I had to call the void __gcov_flush() method, to trigger generation of the .gcda/.gcno files. I set both properties for instrumentation and code coverage to YES for the app and test targets. However after running the tests, when I look in: DerivedData/some subfolders/i386 all I see are files of type: .d,.dia,.o,.swiftmodule and so on
