No. In this case the build was made on an AWS machine of type m6a.large,
which has 2 vcores. I'm usually including the machine type in the hostname,
so that it may be found in the very first line of the full build log:

sbuild (Debian sbuild) 0.85.0 (04 January 2023) on m6a-large-1701732603

The specs for m6a.large machines are available here:

I think the end user should never have to deal with such "useful information".

If it is possible to detect beforehand that the test suite will fail on a given
system, then the package should probably enclose dh_auto_test inside a
suitable Makefile if/endif block.

Alternatively, if the number "2" at the end of the debian/rules
line saying "export TEST_FLAGS=200 12 2" is the number of vcores
requested for the tests, then the package should probably honor
DEB_BUILD_OPTIONS=parallel=n so that no more vcores than available
are requested.

Thanks.
