Previous studies have researched how developer experience affects code quality, but difficulty was ignored although experienced developers are more likely to work on more complex parts of a project. We examine work difficulty by focusing on revised files. Using product metrics, we evaluate file complexity for each type of file origin. Specifically, we analyze three large commercial projects (each with about 250,000 LOC) executed by the same organization to analyze the relationship between previous project experience and developer’s work. Although experienced developers do not necessarily work on more complicated files, they introduce fewer defects, especially if the difference in work difficulty is not significant.

SIGCSEは、米国で開催される最大規模のACM主催会議The SIGCSE Technical Symposium on Computer Science Educationを指し、コンピュータサイエンス教育における最難関のトップカンファレンスである。世界の研究者や実務家は、トップカンファレンスを目標として計画的に研究・実践し、投稿し、採否によらず参加し、議論し、影響を与え、ネットワークを広げる、ということを50年間積み重ねてきている。日本もそれに倣うべきである。本稿では49回目の開催にあたるSIGCSE 2018の様子を報告するとともに、トップカンファレンスの重要性を述べる。
10 new students (incl. 2 international course students from Indonesia) have joined our lab. Welcome! 昨日10名の学生(うち2名はインドネシアからの国際コース学生)が新たに鷲崎研究室に入りました。ようこそ!
3月27日に、広尾学園にて開催の第1回東京国際教育祭 Learn for Life 2018にて齋藤助手が小学生向けのワークショップ「Aliceで3Dアニメなどを作りながらプログラミングを学ぼう」を実施。学習効果調査も実施しました。多くのご参加、有難うございました。渡邊君、南雲君が手伝ってくれました。
On March 24, there were graduation celemony, doctoral degree celebration for D3 Daisuke Saito kun, Wedding Party of Alumunus Koji Tsumura kun, Farewell party, and Get-together for Naoko Shinohara-san’s graduation!
Prof. Washizaki gave a lecture course on Software Quality Assurance at IIITDM-J in Jabarpul, India from Mar 18 to 21. Also he had some research meetings with Prof. Atul and his team.
Thomas and Elayne from the team of Prof. Anthony, University College Dublin visited us on Mar 8 to discuss Mutation Testing and Chatbot. Thank you for comming!

Yuper Lay Myint, Hironori Washizaki, Yoshiaki Fukuzawa, Hideyuki Kanuka, Hiroki Ohbayashi, “Test case reduction based on the join condition in pairwise coverage-based database testing,” 5th International Workshop on Software Test Architecture (InSTA 2018), April 13, 2018, Västerås, Sweden, conjunction with ICST 2018
Testing database applications correctly and effectively remains an issue. This study improves Selected Pairwise Coverage Testing (SPCT), which is a pairwise coverage-based test method for database applications that can discover bugs not detected by conventional methods. Because SPCT considers only selected columns in the SQL query and the conditions in the simple WHERE clause, achieving full pairwise coverage has some redundancies. In this work, we propose a new pairwise coveragebased test method by considering the condition in the JOIN clause to further reduce the redundant parameter combinations. The experimental results are evaluated to confirm the effectiveness of proposed test method compared to SPCT.
