We compare the effectiveness of two methods of random test generation: with and without replacement of test patterns. Expressions for test length and test confidence for both methods are given. Determination of random test length is simpler when tests are generated with replacement, yet most practical random test methods produce tests without replacement. The conditions are obtained such that testing without replacement can be approximated using the simpler approach.
