But it makes sense to keep them separate, in some cases.
Furthermore, it's up to the person developing the tests to write them
as a single program or multiple ones, so he can choose what better
suits his needs. (For an example see src/regress/sys/fs/tmpfs; I
think those different test programs make sense, and collapsing them
all into a single one could be confusing.)
Anyway, that doesn't mean that code is duplicated among the tests.
I'm keeping all the infrastructure centralized so that the test
program's code is minimal. Test programs written in C/C++ rely on a
shared library, and test programs written in sh include a file that
lives in share.

I'm not sure I understand you here. The current layout I have looks
