Easiest way, is to place pump in a vice, taking care not to use too much pressure and soft-wood blocks to protect case....

Plumb up the system with the lift-pump, a small fuel-filter, to the IP inlet, the return to a Clean supply of fuel..

Attach a H.P. line and a spare injector to the first outlet. Prime up the system by using the primer, until bubble-free return flow is observed.

Using a spanner on the pump drive, rotate the shaft. A good pump will deliver fuel, even at hand speed--(It doesnt go much faster when engine is cranking on the starter...).--and a really good pump will deliver at very slow hand speed....

Take care with the spray from the injector, the vapour is dangerous if inhaled and could penetrate skin if directed near it....--

Best direct it into a jar, with a rag around the injector to act as a catcher for the spray/vapour

Try each outlet in turn.

This test will not tell you that the volume of fuel delivered is right, but at least it will tell you that the pump is capable of supplying fuel at the pressures needed, so at least will run an engine if fitted....
