Running the GCC Coverage Tool

Based on the example from here.

(python3) [siavash@pool5 coverage]$ g++ -fprofile-arcs -ftest-coverage test.cpp
(python3) [siavash@pool5 coverage]$ ls
a.out  test.cpp  test.gcno
(python3) [siavash@pool5 coverage]$ ./a.out 
(python3) [siavash@pool5 coverage]$ ls
a.out  test.cpp  test.gcda  test.gcno
(python3) [siavash@pool5 coverage]$ gcov test.c
File 'test.cpp'
Lines executed:83.33% of 6
Creating 'test.cpp.gcov'

(python3) [siavash@pool5 coverage]$ cat test.cpp
int main(int argc, char**argv) {
  int x = 0;
  if (argc > 1) {
    x = 1;
  } else {
    x = 2;
  }
  return x;
}
