You might not have a pressure gauge though.
With no pressure gauge the following can be done to give you an idea of how well the system is working. This is no way near as good as actually measuring the pressure...
...but when needs must =>
Jack up the front of the car so that the wheels can move freely - the car doesn't have to be all the way up in the air - just relive the pressure on the tyres. Alternatively sit the front wheels on slip plates so the steering can be turned easily.
Remove the cap on the fluid reservoir
Start the engine
Turn the steering wheel one way or the other
You should be able to see fluid leaving and bubbling back into the reservoir - if it is just shaking with the engine vibrations it probably isn't pumping.
You can often feel the pressure line for changes in pressure whilst the steering is being used
Sometimes you can hear the hydraulic fluid whizzing / wheezing through the lines.
Like I said a pressure gauge is the best measure - but sometimes looking for the obvious gives a rough idea if you need to fit a replacement pump (or not).
