GCOV
GCOV is a tool you can use in conjunction with GCC to test code coverage in your programs.
...
Build
For building with coverage support you need to add some flags to gcc/g++ compiler and linker:
| Code Block | ||
|---|---|---|
| ||
g++ -fprofile-arcs -ftest-coverage #Or simply --coverage, which includes the previous flags g++ --coverage |
...
| Code Block | ||
|---|---|---|
| ||
#Build ACS cd ACS MAKE_GCOV=1 make build $Build#Build a single module cd <some_module>/src MAKE_GCOV=1 make clean all install |
As a result, you will have a .gcno file for each compiled .o file in your object directory.
...
Execute
The execution is the same as always, you don't need to use a wrapper application or pass any special flag or environment variable. You can either run an executable manually or use an automated testing system such as TAT.
