Well, basically by hand.

I think that Ralf was just saying that, since I'm familiar with the
automake testsuite and interested in extending it, since I presently
have definitely more time to do so than Ralf has, and, above all,
since there's no other regular contributor to automake ATM, if someone
is able to add proper testing for the new feature, that's either me or
the original contributor of the feature (Valentin David).

But it's not like I have a "silver bullet" to write proper tests
which attain complete branch coverage; I just proceed by "common
sense", trying to maximize such coverage.  That's all, sadly.
