Maybe you don't know what the purpose of gcov in the GCC tool set is, maybe you need to adjust the new project at hand, or your

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
The Gtest white Box test tool is used on the embedded platform , which covers the measured function, but does not know the effect of the test, test line coverage, function coverage, branch coverage data. began to study Gcov whether this code
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

C/C ++ has very few statistical tools for code coverage. Compared with Java, there are very few open-source and free tools. It is very rare to use and open-source tools. Finally, we chose gcov-based lcov as the
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.
