What does that say about the minimal collection of gear required in a test 
lab?

If you had a lab with plenty of gear, what tests would you run?

How many different tests would it take to give reasonable coverage?

This is called "the modem testing problem" (:-))  The usual answers are

  1. just my own brand
  2. the most popular, plus mine
