Briefly summarize the test-driven development process.
Answer: Test-driven development (TDD) is an approach to program development in which you interleave testing and code development. Essentially, you develop the code incrementally, along with a test for that increment. You don’t move on to the next increment until the code that you have developed passes its test. Test-driven development was introduced as part of agile methods such as Extreme Programming. However, it can also be used in plan-driven development processes. One of the most important benefits of test-driven development is that it reduces the costs of regression testing.
