Sorry, here I wanted to ask:
 Which variant will be selected when LTP_SINGLE_VARIANT is set?
 Is the selected variant the expected one?

Since the order of test variants is not standardized and is determined
by the author while test writing. Once we used LTP_SINGLE_VARIANT
it still does not guarantee the executed variant is the same for all tests.
Unless people only use it in manual debugging mode.
