gtest custom print display expected value obtained value

[nicola-lunghi]

Hi,
I have a set of test that measure performance that needs to be in a custom range of values to be ok -> if the value is too low or too high other problem could be happening

so I have to check that a value is in an expected range (or tollerance)
for example : I need to have 1Gb/s throughput +-10% on one test.

1. what is the best way to implement this test?
2. there's a way to customize the print and print other than pass/fail also the measured value like:
   RESULT | Expected value | tollerance | Measured value
   PASS | 1Gb/s | 10% | 1.01Gb/s

Any idea?
Thanks,
Nick
