Test-Driven Development [chapter]

Hakan Erdogmus, Grigori Melnik, Ron Jeffries
2010 Encyclopedia of Software Engineering  
Test-driven development (TDD) is a software development approach using a growing scaffold of tests that guide and support the production of code. This entry describes TDD, explains the underlying dynamics, provides a small worked example, and offers a theory of how and why it works. It relates TDD to other approaches that employ a similar style of development and presents a summary of the empirical results about TDD's effectiveness. The entry also raises some of the known concerns and

Adopting it takes a great amount of discipline. However, we cannot say whether TDD is right for everyone and for all types of software: this entry should help the reader decide whether to explore further. Encyclopedia of Software Engineering

Perceptions of Agile Practices: A Student Survey [chapter]

Grigori Melnik, Frank Maurer
2002 Lecture Notes in Computer Science  
The paper reports on the results of a recent study on student perceptions on agile practices. The study involved forty-five students enrolled in three different academic programs (Diploma, Bachelor's and Master's) in two institutions to determine their perceptions of the use of extreme programming practices in doing their design and coding assignments. Overwhelmingly, students' experiences were positive and their opinions indicate the preference to continue to use the practices if allowed.

Agile Methods: Crossing the Chasm

Frank Maurer, Grigori Melnik
2007 29th International Conference on Software Engineering (ICSE'07 Companion)  
An armada of emerging agile methods of software development (with eXtreme Programming and Scrum being the most broadly used) is both gaining popularity and generating lots of controversy. This high-level tutorial gives an overview of agile methods and provides background to understand how agile teams are addressing modern software engineering challenges. Analysis of empirical evidence is used to discuss strengths and limitations of agile methods in various contexts. The participants are

Introducing Agile Methods in Learning Environments: Lessons Learned [chapter]

Grigori Melnik, Frank Maurer
2003 Lecture Notes in Computer Science  
This paper describes the experiences of introducing agile methods in four different academic programs (Diploma, Applied Bachelor's, Bachelor's and Master's) in two institutions during two academic years. It contains suggestions and techniques for bringing agile methods into curriculum. Based on overwhelmingly positive students' experiences this report should encourage other academics that are considering introducing agile methods in their software engineering courses.

Tests and Requirements, Requirements and Tests: A Möbius Strip

Robert C. Martin, Grigori Melnik
2008 IEEE Software  
Surprisingly, to some people, one of the most effective ways of testing requirements is with test cases very much like those for testing the completed system. -Donald C. Gause and Gerald M. Weinberg W hen Donald Gause and Gerald Weinberg wrote this statement, 1 they were asserting that writing tests is an effective way to test requirements' completeness and accuracy. They also suggest writing these tests when gathering, analyzing, and verifying requirements-long before those requirements are

Examining Usage Patterns of the FIT Acceptance Testing Framework [chapter]

Kris Read, Grigori Melnik, Frank Maurer
2005 Lecture Notes in Computer Science  
Executable acceptance testing allows both to specify customers' expectations in the form of the tests and to compare those to actual results that the software produces. The results of an observational study identifying patterns in the use of the FIT acceptance testing framework are presented and the data on acceptance-test driven design is discussed.

Impreciseness and Its Value from the Perspective of Software Organizations and Learning [chapter]

Grigori Melnik, Michael M. Richter
2004 Lecture Notes in Computer Science  
When developing large software products many verbal and written interactions take place. In such interactions the use of abstract and uncertain expressions is considered advantageous. Traditionally, this is not the case for statements which are imprecise in the sense of being vague or subjective. In this paper we argue that such statements should not only be tolerated but, often, they can be very useful in interaction. For this purpose we relate abstraction, uncertainty and impreciseness to

The introduction of degrees of i mpreciseness leads to the question of finding an optimal level. This is interpreted as a learning problem for software organizations . The success can be measured in terms of different cost factors. The design of evaluation experiments is shown as an interdisciplinary task.

Comparative Analysis of Job Satisfaction in Agile and Non-agile Software Development Teams [chapter]

Grigori Melnik, Frank Maurer
2006 Lecture Notes in Computer Science  
Software engineering is fundamentally driven by economics. One of the issues that software teams face is employee turnover which has a serious economic impact. The effect of job dissatisfaction on high turnover is consistently supported by evidence from multiple disciplines. The study investigates if and how job satisfaction relates to development processes that are being used and the determinants of job satisfaction across a wide range of teams, regions and employees. A moderate positive

The evidence suggests that there are twice as many members of agile teams who are satisfied with their jobs (vs members of non-agile teams). The ability to influence decisions that affect you, the opportunity to work on interesting projects, and the relationships with users were found to be statistically significant satisfiers.

Suitability of FIT User Acceptance Tests for Specifying Functional Requirements: Developer Perspective [chapter]

Grigori Melnik, Kris Read, Frank Maurer
2004 Lecture Notes in Computer Science  
The paper outlines an experiment conducted in two different academic environments, in which FIT tests were used as a functional requirements specification. Common challenges for functional requirements specifications are identified, and a comparison is made between how well prose and FIT user acceptance tests are suited to overcoming these challenges from the developer's perspective. Experimental data and participant feedback are examined to evaluate whether developers can use requirements in

A cross-program investigation of students' perceptions of agile methods

Grigori Melnik, Frank Maurer
2005 Proceedings of the 27th international conference on Software engineering - ICSE '05  
Research was conducted on using agile methods in software engineering education. This paper explores the perceptions of students from five different academic levels of agile practices. Information has been gathered through the collection of quantitative and qualitative data over three academic years, and analysis reveals student experiences, mainly positive but also some negative. Student opinions indicate the preference to continue to use agile practices at the workplace if allowed. A way

On the success of empirical studies in the international conference on software engineering

Carmen Zannier, Grigori Melnik, Frank Maurer
2006 Proceeding of the 28th international conference on Software engineering - ICSE '06  
Critiques of the quantity and quality of empirical evaluations in software engineering have existed for quite some time. However such critiques are typically not empirically evaluated. This paper fills this gap by empirically analyzing papers published by ICSE, the prime research conference on Software Engineering. We present quantitative and qualitative results of a quasi-random experiment of empirical evaluations over the lifetime of the conference. Our quantitative results show the quantity
