Testing a system call in qemu

I have just started to look into the Linux kernel development. I have a kernel image bzimage and an initrd which works fine on qemu. Now I have compiled the kernel after adding a new sys call to it. I want to test the system call on qemu what is the preferred way of doing this, (if any) ?

syscall() function in unistd.h can be used.

Refer the following blog which does exactly same.
