You could force this by let-binding system-type, like

--8<---------------cut here---------------start------------->8---
(let ((system-type 'gnu/linux))
  (rgrep-default-command "search" "*" nil)
  ...)

(let ((system-type 'darwin))
  (rgrep-default-command "search" "*" nil)
  ...)
--8<---------------cut here---------------end--------------->8---

In the windows-nt case, the function w32-shell-dos-semantics is called,
which does not exist on other systems. So you must mock it up to return
either t or nil:

--8<---------------cut here---------------start------------->8---
(let ((system-type 'windows-nt))
  (cl-letf (((symbol-function #'w32-shell-dos-semantics) #'always))
    (rgrep-default-command "search" "*" nil)
    ...))

(let ((system-type 'windows-nt))
  (cl-letf (((symbol-function #'w32-shell-dos-semantics) #'ignore))
    (rgrep-default-command "search" "*" nil)
    ...))
--8<---------------cut here---------------end--------------->8---
