See runtests and the respective phpt tests in the php releases or in
cvs (php-src module). It is possible to emulate file upload using the
CGI sapi (I'm not sure if we have tests using this feature). It is
even possible to emulate almost all http behavior (from a server point
of view) with it.

However, as far as I remember phpunit does not "fork" php and uses the
current instance and that will not allow you to use the phpt method.
If it is not the case, then it should be relatively easy to port the
phpt system to phpunit (or use phpt :).

It is not the ideal solution if you use phpunit, but it may already
give you something to test or use.
