note you can do 'typedef testing::Test SessionModelAssociatorTest'; if you like.
 Or if you dont think you'll ever need boilerplate (probably not the case here)
you could remove this altogether and just use TEST(...,...) below.

Done.

instead of the extra clause at the end, could we just create a raw pointer here
and immediately push_back on session->windows?

Done.
