This is a common confusion: if you do not explicitly list the 
prerequisite among the tests you want to run, then it will not be run.  
We see prerequisites as purely an optimization: they provide a way of 
skipping some tests if earlier tests do not work the way you think.  
It's possible that this was a bad design decision; it is certainly true 
that you are not the first person to have been confused.  However, it is 
how QMTest presently works.
