HWUT：命令行参数

Question

在命令行提示符下，是否可以将参数传递给 hwut 命令，例如，为了使用该参数作为标识符来打开特定的串行端口？

Answer 1

I guess, the easiest way is to use environment variables. Let's say your test is written in "C", then do

   set MY_VARIABLE=4711    # DOS
   export MY_VARIABLE=4711 # Unix & Co
   hwut my-test.exe

where the file "my-test.c" is the source of "my-test.exe" and contains

   #include <stdlib.h>
   ...
   int main(int argc, char** argv)
   {
       ...
       const char* MyVariable_str = getenv("MY_VARIABLE");
       int         my_variable;

       my_variable = MyVariable_str ? atoi(MyVariable_str) : -1;
       ...
   }

The propper solution, of course, is to have some configuration file which is configured globally and parsed by the test applications. The overhead for that, however, might not always be justified.
