These are (fairly rare) good use-cases for `cl-letf`:
(cl-letf (((get 'cus-edit-tests--obsolete-option-tag 'saved-value) '(t)))
(customize-saved)
(should (search-forward cus-edit-tests--obsolete-option-tag nil t)))

Indeed. I didn't know about cl-letf, thanks.
BTW, C-h f cl-letf RET
shows a link to the info node (cl) Function Bindings. Maybe a better
link is (cl) Modify Macros.
