How to exclude tests from inspections builds

Hi there,

I'm trying to configure the TeamCity inspection runner to ignore the test
directories, but failed to figure out how, so far.

When running inspections in IDEA one has a checkbox allowing the inclusion/exclusion
of the test sources. Similarly, the server side duplicate finder has the
option to exclude the test sources from that build. How can this be achieved
for an inspection build?

I'm running TC 3.1, BTW.

TIA,
Andrei
