Yes, this is what is done in the classes that already have a constructor argument, the tests do use it and use hard coded funny constants to seed the generator. > > In Mahout, we did this by having a static method in a utility class for > getting a standard generator for either testing or normal operation.

Doesn't that induce problems when new tests are included which change the running order of the tests or when only one test is run ? In these cases the current state for the generator will not be the same in each situation. Do tests reseed the generator when they start ?
