Wrote an Android App to help practice this - has a bunch of different matching games similar to what you described. Settings for 4,5,6 string basses.

I developed a free Android app to help memorize the notes on the fretboard called "Fretboard Learn". The app has a bunch of game modes which let the user practice matching the name of note to a position on the fretboard (identifying the highlighted note, finding note X on string Y, and finding all X notes on the neck). It's helped me a lot using it while I worked on it. Try it out and let me know what you think (any features or options I should add?)
