lcov

Refer to this coverage report . . I know that my test cases are exercising the exception handling, however the lines are still being reported as not covered. . . This has been the case in all of my objective-c projects for a while now. . . . is there a way to fix this? 来源： https://stackoverflow.com/questions/14796711/why-doesnt-lcov-report-exception-coverage

I'm working in a C++ Project with a structure similiar to the following: --- /src |--comms |--utils |--interfaces … CMakeList.txt --- /test |---test1/ |--main.cpp |--CMakelists.txt --CMakeLists.txt I do need to control the coverage of my tests and for this purpose I use GCOV and LCOV in this way: Enable coverage flags in all CMakeLists.txt to let the generation of .gcno files. SET(CMAKE_CXX_FLAGS "-g -O0 -Wall -fprofile-arcs -ftest-coverage") SET(CMAKE_C_FLAGS "-g -O0 -Wall -W -fprofile-arcs -ftest-coverage") SET(CMAKE_EXE_LINKER_FLAGS "-fprofile-arcs -ftest-coverage") Run test, generating the

When I add LCOV_EXCL_START/STOP tags to my C++ code, it does not seem to have any effect on my gcovr report. Does someone know why this occurs? I have the following: $ tree . ├── build ├── include │ └── a.h └── tests └── test_a.cpp and $ cat include/a.h void f (bool x) { // LCOV_EXCL_START if (x) throw 1; // LCOV_EXCL_STOP } and $ cat tests/test_a.cpp #include "a.h" int main () { f (false); return 0; } But line 5 throw 1; is included in the gcovr report, even though it is surrounded in exclude tags: $ g++ -c -O0 -fprofile-arcs -ftest-coverage -fPIC --coverage -I include ./tests/test_a.cpp -o .

I am trying to run coverage on my project, after updating to Ubuntu 16.04. I get Deleted 665 files Writing data to coverage.info.cleaned lcov: ERROR: cannot write to coverage.info.cleaned! CMakeFiles/coverage.dir/build.make:57: recipe for target 'CMakeFiles/coverage' failed make[3]: *** [CMakeFiles/coverage] Error 13 CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/coverage.dir/all' failed make[2]: *** [CMakeFiles/coverage.dir/all] Error 2 CMakeFiles/Makefile2:74: recipe for target 'CMakeFiles/coverage.dir/rule' failed make[1]: *** [CMakeFiles/coverage.dir/rule] Error 2 Makefile:129:

I am wondering if there is the possibility to tell lcov to ignore some lines in a source files, ie. do not report them as unvisited. I am looking for a solution that can be put in the code itself, like: int some_method(char some_var, char some_other_var) { if(some_var == 'A') { if(some_other_var == 'B') { /* do some real stuff here */ } else { LCOV_DO_NOT_REPORT_NEXT_LINE // **<-- this?? ** NOT_IMPLEMENTED("A*") } } else { NOT_IMPLEMENTED("*") } And the necessary background: A big piece of code like the one above is being tested in a series of unit tests, but since this code is still under

I measure coverage for my code using gcov library and I would like to generate coverage report in user-friendly format. I've found lcov utility for that, but it's not compatibile with Windows environment (mainly because of the way the paths are parsed). Does anyone know about actively supported lcov port for Windows? It seems that making it work on Windows would be quite easy (it think it might even be solved by few creative batch/perl scripts that mimic the behavior of unix shell commands), and the tool is quite useful, so I suppose someone might have already done it.
