How to test for exit(EXIT_CODE)?

[yuw444]

Hi, I like to test for the exit code.

Below is a minimum example

#include <criterion/criterion.h>
#include <stdio.h>

void foo(int a)
{
  if(a == 1) exit(1);
  if(a ==2) exit(2);
  return;
}

how to capture the exit code, such as 1, 2? I have try cr_fail(), cr_exit() without luck.

Thanks

Think I'm gonna pass on using criterion after finding out this wasn't added half a year later. Need it right now.

Fellow criterion user here, have you looked at the .exit_code directive?
Here is an example from the criterion source code:

Test(exit, expected_exit, .exit_code = 42)
{
exit(42);
}

The .exit_code directive allows a non zero exit status to be declared as the expected result for a given Unit Test. By default, zero (0) is the normal exit status when executing a Unit Test and a non zero status would fail the test.

where:
.exit_code Is the name of the directive.
= A numeric value indicating the expected exit status for the Unit Test. From the example, the Unit Test is behaving as expected when returning a value of 42 – therefore, the test would not be marked as a failure despite it returning a non zero exit code, since it matches what was declared in the directive. Specifying a zero value for this directive is allowed but not needed, since it is the implied default.

They also discuss this in their documentation, link is:
