It's according to what specification you request.
For example , if ANSI/TIA/EIA 568B.2 was specfiy to test Unshielded Category 5e erally, They will test DC Resistance , Mutual Capacitance Attenuation , NEXT , FEXT , Return Loss, Input Impedance .......
They will also test Attenuation Skew... @ 40 0C & @600C
