When using gcov, you must first compile your program with —coverage GCC option. The gcov utility does not produce any time-based data and works only on code compiled with the GCC suite. Retrieved February 12, Nanual article speaks solely from the viewpoint of a C programmer working on a Linux PC or similar systems.

Static code coverage analysis is much faster and simpler since the generated object file need not be executed. Detailed coverage report will manuzl available in the lib. How I can add the above flags while making, in such a way that after execution of the projects i need to get coverage of the execution in project source files.

This will mnaual the following files. Function ‘libfn1’ Lines executed: This will generate the following files lib. Static code coverage analysis is done by analyzing the test code and the actual code to primarily estimate the function call coverage.

When the code base grows, manual testing fails to meet the requirements and we have to move into automated systems for testing. The line counts mankal be seen in the first column of the output. All large scale, usable C code is written in the form of blocks of code enclosed in functions. Gcov is a source code coverage analysis and statement-by-statement profiling tool.

To illustrate the usage of gcov, we will consider a very minimal library lib. The program will try to create the needed directory structure, if it is not already present. The percentage of lines of actual code that gets executed when a test code runs is called the coverage of the test code. However, the CI system is only as effective as the test.
