Can I somehow cancel enabling of my minor-mode?
Example of what I want:
(define-minor-mode test-mode
"documentation"
:init-value nil
(if test-mode
(if some-condition
cancel enabling of test-mode. exit
actions-when-enabling)
actions-when-disabling))

To cancel, you can (setq test-mode nil).

IIUC, it will still run any hook associated with the mode like for any
mode change (+ show the message "Test mode disabled"). Not too bad, but
not exactly like cancelling either. Perhaps some (user-error ...) would
be ok in that case ?
Otherwise, the OP could define a helper function `test-mode-maybe'
which would check and only activate if it's ok.
