True.

Looks OK, chances of someone making MYTST_VARIABLE is quite small,
and we can always improve that regex if needed.

Couple notes:
- these seem to be missing: TST_DEVICE, TST_MODPATH, TST_CHECKPOINT_*, TST_NEEDS_CHECKPOINTS
- doc page mentions "TST_NEEDS_CMD" and "TST_NEEDS_CMDS", the latter looks like typo.
