In a software development group of IBM Retail Store Solutions, we built a non-trivial software system based on a stable standard specification using a disciplined, rigorous unit testing and build approach based on the test-driven development (TDD) practice. Using this practice, we reduced our defect rate by about 50 percent compared to a similar system that was built using an ad-hoc unit testing approach. The project completed on time with minimal development productivity impact. Additionally… Expand
On the Effectiveness of Unit Test Automation at Microsoft
TLDR
Results indicate automated unit testing is beneficial but additional quality improvements may be realized if the tests are written iteratively, as is done with the test driven development practice, for a similar time increase. Expand
Introducing Test Automation and Test-Driven Development: An Experience Report
TLDR
An approach to software component-level testing that in a cost effective way can move defect detection earlier in the development process and decreases the development lead-time significantly is identified. Expand

Continuous Test-Driven Development - A Novel Agile Software Development Practice and Supporting Tool
TLDR
In this article, the CTDD practice and the tool that is intended to use to support and evaluate theCTDD practice in a real world software development project are described and described. Expand
Evaluation of Test-driven Development - An Industrial Case Study
TLDR
A development project carried out in a company is presented in which some of the claims of the test-driven development approach are found to be valid, but there are also difficulties with applying the approach. Expand
The effectiveness of test-driven development: an industrial case study
TLDR
The results indicate that the TDD developers produced higher quality code that is easier to maintain, although the productivity of the developers did observe a reduction in productivity. Expand
Evaluation of Test Driven Development
This thesis is about a development practice that will help to create clean code that works, called Test Driven Development. Test Driven Development (TDD) is part of the Extreme ProgrammingExpand
A successful application of a Test-Driven Development strategy in the industrial environment

TLDR
The main conclusions drawn from this project are that ATDD contributes to clearly capture and validate the business requirements, but it requires an extensive cooperation from the customer; and that UTDD has not a significant impact neither on productivity nor on software quality. Expand
On the Sustained Use of a Test-Driven Development Practice at IBM
TLDR
A post hoc analysis of the results of an IBM team who has sustained use of TDD for five years and over ten releases of a Java-implemented product indicates that the TDD practice can aid in the production of high quality products. Expand
The Impact of Test Driven Development on the Evolution of a Reusable Framework of Components – An Industrial Case Study
TLDR
An empirical study of a framework of reusable components used in building new applications and provides services to these applications during runtime shows benefits in terms of reduced mean defect density, when using TDD, over two releases. Expand

An initial investigation of test driven development in industry
TLDR
It is found that the TDD developers produced higher quality code, which passed 18% more functional black box test cases, however, TDD developer pairs took 16% more time for development, which supports that TDD has the potential of increasing the level of testing in the industry. Expand
