The issue is that obj_q need be initialized and elements need be
inserted in both testing cases. It is not straightforward or a good idea
to construct the q in a static way. Sharing the structures would make
one test depending on another, since the q needs be torn down and
restored to the uninitialized states after one test, which has to be
manually done. Or we need to add a test to just init the q before these
two tests. That will still create dependence issue.

So I would leave it as it is.

OK, what about sharing wire_q ?
