Unit test which test output of a program

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

static void redirect_all_stdout(void)
{
    cr_redirect_stdout();
    cr_redirect_stderr();
}

Test(test_output, test_output_string, .init=redirect_all_stdout)
{
    write(1, "test output\n", 13);
    cr_assert_stdout_eq_str("test output\n");
}

Unit test which test string output of a function

#include <criterion/criterion.h>

Test(test_string_compare, test_string)
{
    char test[] = "test string";

    cr_assert_str_eq(test, "test string");
