Function Coverage
Function coverage measures which functions are called during test.
It is the most lightweight instrumentation mode regarding the overhead to the program
execution. There is no analysis how the function’s internal program flow has been
exercised, hence this is a rather weak measure. Function coverage serves to give a
rough, compact overview of the thoroughness of the test cases.
Note: Function coverage
is available
- as instrumentation mode with the ctc command
-i f
, - with ctcpost with the option
