About Me

I am currently an Associate Researcher at Department of Computer Science and Technology, Nanjing University. I am also part of the Group in Software Testing (GIST). My current research interest lies in the area of software testing and maintenance, where I am interested in solving software development problems by techniques that exploit artificial and human crowd intelligence.

I received my PhD degree from Nanjing University in June 2018, under the supervision of Professor Changhai Nie. I have been a visiting student at CREST of University College London (UCL), from September 2016 to August 2017. My supervisors in CREST are Professor Justyna Petke and Mark Harman.

我们招收博士、硕士以及南京大学本科生，欢迎对智能软件测试感兴趣的同学随时邮件联系 :-)

Teaching

Software Testing (Autumn)
This course is concerned with concepts, techniques, and applications of software testing, which especially covers a broad range of popular and powerful testing techniques. The desired learning outcome is to be able to use multiple (automated) testing techniques to effectivelly test and evaluate given software systems.

Projects

Combinatorial Testing Repository

Combinatorial testing is a potentially powerful testing technique to reveal software failrues. This repository aims to provide a full coverage of the publications in the literature of combinatorial testing.

CCAG

CCAG (Constrained Covering Array Generation) is a reference implementation of constrained covering array generation algorithms, which supports the substitution and comparison of different constraints handlers.
