Query: A Longitudinal Cohort Study on the Retainment of Test-Driven Development   Background: Test-Driven Development (TDD) is an agile software development
practice, which is claimed to boost both external quality of software products
and developers' productivity. Aims: We want to study (i) the TDD effects on the
external quality of software products as well as the developers' productivity,
and (ii) the retainment of TDD over a period of five months. Method: We
conducted a (quantitative) longitudinal cohort study with 30 third year
undergraduate students in Computer Science at the University of Bari in Italy.
Results: The use of TDD has a statistically significant effect neither on the
external quality of software products nor on the developers' productivity.
However, we observed that participants using TDD produced significantly more
tests than those applying a non-TDD development process and that the retainment
of TDD is particularly noticeable in the amount of tests written. Conclusions:
Our results should encourage software companies to adopt TDD because who
practices TDD tends to write more tests---having more tests can come in handy
when testing software systems or localizing faults---and it seems that novice
developers retain TDD.
