A Case Study of How Test-Driven Development Improves Software Quality

The purpose of this study includes the Test-
driven development (TDD) software development

approach, which involves developing tests before
implementing a feature into a software Application.
With comparisons to Test Last Development (TLD), this
study is focused on examining the effects of TDD on the
productivity and quality of internal and external
software. Results revealed an improvement in the quality
of the internal software and a significant improvement
in the qualityof the external software. In general, TDD
seems to result in the development of software that is
more modular, simpler, and more tested. To properly
comprehend how TDD affects software development,
refer to the case study provided below.
