All context variables live in the Context object, which is passed to 
Resource.SetUp() as well as Test.Run(), where you can access as well as 
modify them.

QMTest provides only a weak dependency between tests: By registering 
'prerequisite' tests you can instruct QMTest that a dependent test 
shouldn't be run if a prerequisite failed (for example). However, you 
can still invoke the dependent test only, and it will run happily even 
without the prerequisite test being executed first. This is a mere 
optimization that allows to skip tests if it is clear that they aren't 
even expected to pass if a prerequisite test failed, too.
(see 
http://www.codesourcery.com/public/qmtest/qmtest-snapshot/share/doc/qmtest/html/tutorial/concepts.html#concepts-tests)
For real dependencies you may use a Resource instead.

No. However, resources that a test depends on, will.

Thanks !
