These are discharge lamps so they do not contain a filament. Attempting a simple test, like continuity using a DVM, will always show open circuit even with a good lamp.
These lamps need a large potential across the electrodes to operate, so, there isnt any real way to test them other than in a test jig using the correct control gear .... or substitute a known good lamp into a suspect fitting.

You either need to make up a test rig board with the correct control gear and lamp holders for each type of lamp you ish to test or the easy way is
to buy a device called a lamp tester city electrical factors do them and a few places sell them online.
cost around £50 ish its like a probe you touch onto the lamp and of the lamps good it will ignite the gas inside

thought that maybe the case so will wait till an old fitting comes along...cheers
I first seen a lamp tester demonstrated by a sales rep from CEF last April we where having issues with brand new fittings not working this tester proved the CDMT lamps where ok so eventually the cause was found to be the control gear was not suitable.
A good source for old sodium lamp gear trays is your local councils street lighting depot, they only have to break the old ones up for recycling anyway.
Theres some quality lanterns going to scrap as the the PFI schemes roll out the new LED lights.
