Conclusion:TDD is a recommended technique for software projects with a long horizon or when it is critical to minimize the number of bugs and achieve high code coverage.īackground: Over recent years, software teams and companies have made attempts to achieve higher productivity and efficiency and get more success in the competitive market by employing proper software methods and practices. Lastly, isolating the Intermediate developers from the Novices had significant impact on the code quality. code coverage has been observed between the Intermediate and the Novice developers - as opposed to TLD, which was easier to follow. At the same time, TDD proved to have a considerable entry barrier and was hard to follow strictly, especially by Novices. Additionally, TDD narrows the gap in code coverage between developers from different competence blocks. Results: Statistically significant advantage of TDD in terms of external code quality (1.8 fewer bugs) and test quality (5 percentage points higher) than TLD. The resulting implementations had LOC order of magnitude of 10k.
Also, it was analysed if there is any difference between the code created by shared efforts of developers with different competences and the code created by participants isolated in the competence blocks.
A separate group of code repositories was used to work without unit tests, to verify that the requirements were not too easy for the participants. The participants developed only business logic and were separated from infrastructural concerns. The resulting code was verified for process conformance. Method: The experiment is based on a randomized within-subjects block design, with participants working for three months on the same requirements using different techniques, changed from week to week, within three different competence blocks: Intermediate, Novice and Mixed. The aim is to evaluate if there is a significant difference in external code quality and test quality between these techniques. Objective: Examine the impact of TDD and TLD on quality of the code and the tests. An empirical comparison is presented, with 19 participants working on an industrial project developed for an energy market software company, implementing real-world requirements for one of the company's customers. Pedagogical implications and instructional techniques which may foster TDD adoption will also be referenced.Ĭontext: There is still little evidence on differences between Test-Driven Development and Test-Last Development, especially for real-world projects, so their impact on code/test quality is an ongoing research trend.
Potential dangers with TDD are identified regarding programmer motivation and discipline. This study demonstrates the viability of teaching TDD with minimal effort in the context of a relatively traditional development approach.

In addition, iterative development approaches that include automated testing demonstrated benefits over a more traditional linear approach with manual tests. Results from this study indicate that TDD can be an effective software design approach improving both code-centric aspects such as object decomposition, test coverage, and external quality, and developer-centric aspects including productivity and confidence. Students in three groups completed semester-long programming projects using either an iterative Test-First (TDD), iterative Test-Last, or linear Test-Last approach. The experiment was conducted with undergraduate students in a software engineering course. This paper describes a controlled experiment that examines the effects of TDD on internal software design quality. Test-driven development (TDD) is an agile software development strategy that addresses both design and testing.
