test-in-container: Moving a test to a particular location *before* execution?

[Carlos O'Donell]

DJ,

In developing tests for dynamic string token substitution
in DT_RUNPATH, DT_PRATH and LD_PRELOAD etc, I found that
$ORIGIN is hard to test because I want this kind of behaviour:

(a) Create the chroot.
(b) Move the test into the chroot into the $ORIGIN expected location.
(c) Run the test in the container.

The (c) part doesn't work like I expect because test-container
is running the binary relative to the build path.

I think I might need some kind of env var like TEST_RUN_FROM=/path/
where the binary is copied into the path and then the $filename is
executed from that path.

Does that make sense?

For DSOs and other files I can move them all into the chroot by
using the setup script, but the executable can't be moved like
that because the target of execution is given to test-container by
the makefile target.

Carlos.
