Stubs and test-driven development

TDD stands for “test-driven development”

Everything your program needs to do is turned into a test case. You write the tests first, before writing the program! When the tests pass, you can be reasonably confident that it works fine (assuming you made very thorough tests).

A stub a piece of code used to stand in for some other programming functionality. In this class it will be used as a temporary substitute for yet-to-be-developed code.
