Can't inflate my bike tires
Even easier tests:

hold your thumb over the end of the hose and pump.  You should feel pressure build.
visit your local bike shop - many of them have a self-service air pump somewhere outside for the convenience of customers.
visit a bike repair stand in your city, if you have one
visit a bike cooperative
ask a fellow cyclist if they can loan you a pump because yours isn't working
visit your local service station/gas station/petrol station.   With care, you can use a car tyre inflater.   It will only take a second so don't overdo it.
