Abstract
Test-Driven Development, known by its acronym TDD, is one of the many development approaches to have gained traction through the Agile software development movement. It is based on the idea of developing software using a test-first perspective: first, a failing executable test is written; then production software is written capable of passing the test. Accordingly, as its name suggests, the development of production software is being driven by the test. This chapter explores TDD.

In the context of computer science, an argument can be made that a binary integer value of zero is a positive number because its high-order bit is 0, just as it is for all positive integers. Even more absurd is the argument that can be made for packed decimal numbers: that a value of zero is positive when the low-order nibble of its final byte is the binary equivalent of hexadecimal value “A” or “C,” negative when that low-order nibble represents hexadecimal “B” or “D,” and unsigned when representing either “E” or “F.” Here we will simply agree that a value of zero is to have neither a positive nor negative sign.
