If it is a removable tube it may have black marks inside the tube near the end caps. If you have an electrical continuity tester you should see a current flow through the starter filaments wired between adjacent pins at each end of the tube. This can be done with torch bulb and battery or LED key ring etc. When the stater filaments fail the tube must be replaced

If you have multiple bulbs in the fixture, you can also compare the brightness of the other bulbs to determine if one is burnt out.
