You're missing a:

	TEST_PASSES_SANITIZE_LEAK=true

Above this line:

Which tells us that this new test doesn't leak (yay!)

I think we can do away with this helper, we use the argument support once, and for the rest we can inline the trivial command...

grep -F ?

This helper is less trivial, but more obvious would be a "run command and assirt xyz about the output" helper, see e.g. test_stdout_line_count.

Also: Odd to use a sub-shell when the helper takes -C...

Drop the sub-shell and use test_config?
