Answer
- D An alternative version serves as a pseudo-oracle whose outputs are compared with those of the system under test
Explanation
In back-to-back testing, the same inputs are fed into the system under test and into a second version of the system, and the outputs are compared. The second version serves as the yardstick (pseudo-oracle). It may already exist or be built specifically for the test.
