RFR(XXS) : 8177709 : Convert TestVirtualSpace_test to GTest

[Igor Ignatyev]

Hi Thomas,

1st of all, thanks for looking at it, appreciate that.

it seems we can. there are two ways I can fix that either replace ASSERT by EXCEPT or introduce a text fixture w/ SetUp and TearDown. which do you prefer?
