Test-Driven Development with the Focus on Inexperienced Programmers: A Literature Review.

University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

Abstract: Test-driven development is a software development practice that prompts developers to write tests before writing source code. Studies report varied results on the effects that test-driven development has on the development process, and how this practice compares to other development practices, such as more traditional test-last development methodologies. There also seems like there has not been a discussion around the possible problems that a developer could encounter when adopting this technique, something that seems relevant to making accurate assumptions on the usability of the practice. A literature review was conducted, where the subject of test-driven development is examined with a focus on how inexperienced programmers interact with the practice and what effect it has on the product, in terms of external quality, productivity, number of test written and test coverage. The results suggest that there are no significant differences in external quality and productivity between TDD and TLD. The results also suggest that divide and conquer and refactoring are skills that ease the process of adopting the test-driven development practice.
