No. It tries to do the simplest thing, which is to allow test conflicts,
but at least make them obvious. It's then up to the developer to resolve
them, or to explicitely reset globals between tests.

Here, of course, you want to do the opposite of normal behaviour. You
actually want to maintain a global between tests (why?). This should be
fine. Something odd is happening.

Unless each test is executed in it's own process, this is impossible.
Right now that kills performance, although it will in future be added as
an explicit option for particular test cases.

This is to give the illusion that file scope variables will still be
visible in the test methods )I think - can't remember). It imports these
variables, but does not reset any other globals.

Could you see if your variable is visible in get_declared_vars().
