In the initial days of software development, software testing was considered a phase in the software development life cycle. As software development methodologies are evolving, the importance of including testing in multiple phases of the project has increased. Software testing is the process of finding bugs in the software and making the software bug free. It plays an important role in software development, to assess and expand the quality, reliability, and performance of the product.

Test-driven development has two levels, namely Acceptance test-driven development (ATDD) and Developer test-driven development (DTDD). The following diagram represents the steps involved in this process...
