You probably need to define what you mean as "complete unit test".
Are you refferring to the motor as well? What about the pipework and motor starter?
What tests you can do will depend on the instrumentation you have and the pump configuration.
Likewise what is the role of the pump? For example if it was on a fire control system the testing might be different to what you would do for a pump on a municipal water supply.

Hydraulic performance test, mechanical run test, hydro pressure test????

Errr,
1) Put all the bits together (motor, pump, auxiliaries)
2) Plug the motor in or put fuel in it
3) Connect the inlet and outlet piping to suitable pipes and valves
4) Turn it on
5) Do some tests
6) take off the piping and dry the pump
7) unplug the motor
8) Get lots of people to sign the test certificate, especially the client
8) Take it to site
job done
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

LittleInch: you forgot to add,
Install it onsite
Run the pump
Discover the pump doesn't perform as expected
Log onto eng-tips and tell us something wrong with the pump
Etc.

Complete Unit Test is a test aimed at checking mechanical integrity of the pump when assembled as a complete unit with all auxiliaries. As such, regardless of the pump type (split casing or otherwise), please note salient features of Complete Unit Test :
- It is carried out with contract drivers, contract coupling, contract mechanical seals, contract lube oil system skid (as applicable), contract seal support system skid (as applicable), contract vibration and temperature monitoring system components (probes typically).
- It is not the intention of checking hydraulic performance of the system, which is usually carried out through Performance Test. In this test, bearing vibration, seal leakage and noise are usually checked.
- All contract components are mounted and assembled at pump manufacturer's shop and then this machine is run for 4 hours or so.

Consider referring to HI 14.6, Appendix D for the various factory tests and what are included (e.g., performance, hydrostatic, NPSHr, mechanical) along with what instances in which they are generally recommended. From this thread, it sounds like the original poster may have been inferring hydrostatic and mechanical, but that is merely an inference. Certainly all are good.
