Re: [QF-Test] Serialization of Dependencies

Hello Mark,

I guess answering that question is my job... :-)

I'm considering implementing something akin to a 'Call dependency'
node that would let you resolve dependencies from any point in a test.
Perhaps with an option to only roll back the stack up to a given point
without rebuilding it anew.

On the other hand I have not yet been convinced that this is really
necessary. Same for your case. Ask yourself: Why do you need to
restart the application? What's the difference between the
invocations? Let's say it's a parameter for startup. Put that
parameter in a variable and make that variable characteristic for the
"Application started" dependency. That way, if your app is running
with one setting your next 'Test-case' depends on the app being
started with a different setting - meaning the variable now has a
different value, QF-Test will roll back the dependency (i.e. execute
it's Cleanup node which is supposed to stop the application) so that
upon execution of the new Setup it will need to start the app again.

If you really need to stop and restart the app within a single
test-case, move startup and shutdown sequences to procedures which you
can call from the dependency as well as from any other place.

I know, that's not quite the same because it doesn't take care of
proper rollback of the dependency stack.

Further input, anybody?

Best regards,
    Greg
