If the tests are not present it can be:
 1) the unit tests are not compiling.
 2) the unit tests are not instrumented (should not be the case if part of QtBase)
 3) make check does not execute the unit test.
 4) results are not collected

Let me have a look on it.

Rohan, this analysis is the first one provided, and I you know better than everybody that
maintaining the test suite is not an easy job.
That's why it is important that if something is not correct that the community report it. 
This is the only way to get accurate measurements.
