C ++ code coverage profiling with GCC/gcov

The coverage analysis with GCC/gcov includes three following steps
* Instrumented application build-libraries, executable (s), and profiling artifacts (*. gcno files) are created* The application test run (s)-the runtime c
Gcov is a code coverage tool that can be used in C/s + +, and is a built-in tool for GCC. Here's how to use Gcov to collect code coverage information.To collect code overwrite information with Gcov, you need to add these 2 options "-fprofile-arcs-ftest-coverage" when GCC compiles the code, and compile this simple program
Gcc-fprofile-arcs-ftest-coverage
Add gcov to cmakeCodeCoverage test support
(Jinqing's column)
Add the enable_gcov option to root cmakelist.txt:
Option (enable_gcov "enable gcov (debug, Linux builds only)" Off)
If (enable_gcov and not Win32 and not Apple)Set (cmake_cxx_flags_debug "$ {cmake_cxx_flags_debug}-fprofile-arcs-ftest-coverage ")Set (cmake_c_flags_debug "$ {cmake_c_flags_debug}-fprofile-arcs-ftest-coverage ")Set (cmake_exe_lin
The unit test coverage rate means that each line of code should be covered by unit tests. Therefore, it is necessary to write a unit test for each method. In addition, if there are many if statement branches in this method, it should also be covered in unit test.
In the world of C, we can use the gcov tool to calculate the coverage rate. It moves every unit test and then counts the execution of each line of code.
Execute the cunit program, generate two XML files, xxxx-Listing.xml, xxxx-Results.xml and so on (/usr/local/share/cunit/) and put them in the same directory, in this way, you can use IE to open these XML files and see the UT execution.
Gcov usage:
GCC compilation options:-fprofile-arcs-ftest-coverage, connection options-lgcov
Generate file *. gcno during compilation
The gcda file is generated for each source code file during execution,

However, if the project is a mingw project, although it can be compiled using the mingw GCC, it cannot be compiled using gcov, even if the-fprofile-arcs-
