9. C. Test-driven development focuses on writing
code that allows a previously written test (that

should operate.
11. B. unittest.TestCase is a special class that is used
to access the unittest module’s capabilities.CHAPTER 6
1. A. Southbound APIs send information down to
devices within the network.
2. A, B. Because asynchronous APIs do not have to
