If you run

make test VERBOSE=1

you'll see that the command line used to execute all the tests is a call to ctest.

If you run

ctest -R alkimia-alkinvoice

then only the failing test will be run.

If you run

ctest -R alkimia-alkinvoice -VV

then only the failing test will run and all of its output will also be displayed.
