7.1 Running a test in a subprocess

The following API allows us to run a test function in a subprocess. Example:

static cctests_child_process_function_t child_function;

void
test_1_1 (cce_destination_t upper_L)
{
  cctests_call_in_forked_process(upper_L, child_function);
}

void
child_function (cce_destination_t L)
/* This is run in a subprocess. */
{
  cctests_assert(L, true);
}

Function Prototype: void cctests_child_process_function_t (cce_destination_t L)

Type of function to call in a subprocess.

Function: void cctests_call_in_forked_process (cce_destination_t L, cctests_child_process_function_t * child_function)

Fork a process:

• In the child: call child_function; exit successfully if the function returns; exit with failure if the function raises an exception. The child process is terminated with a call to the standard function _exit(). The child function might terminate the subprocess by itself.
• In the parent: wait for the child termination; assert that the child process terminated successfully.
