Test-driven strategies help you develop highly usable software. In this course, you'll explore a number of test-driven development strategies, including test-driven development, test first development, acceptance test-driven development, traditional software testing, and unit testing. You’ll start by examining the TDD cycle, TDD best practices, and the TFD process. You’ll then examine the similarities and differences between TDD and TFD, as well as TDD and test last development. Next, you’ll learn about the ATDD process and how TDD compares with ATDD. You’ll look at unit testing, including its purpose, best practices, characteristics, and testing tools. Lastly, you’ll see how to perform unit testing with frameworks.
