> Actually instead of cwd here, it would be nice to have srcdir or testdir. There is g_test_build_filename() in glib 2.38, not sure what we should do without it. Ideas?

Maybe just via environment variables?


We seem to do the same with MALLOC_PERTURB_ already (though there's probably
less options there), and it's consistent with how we control
QGA_TEST_SIDE_EFFECTING currently.

Also, if we default to cwd things should still work for running the test
executable directly.

g_test_build_filename seems to do similar under the covers as well,
though it is a bit more tedious to have to add to every test target we
want access environment variables in. Would be nice if
tests/Makefile.include could do it automatically via common
dependencies, but I'm not sure if that's doable.
